Tomboyish Name

"Mamma Jacobs: What did you say your name was? Brandon? Butch? Chuck: Chuck? Mamma Jacobs: Chuck! I knew it was something unladylike."

- Pushing Daisies, "Girth"

Basically, a girl has a boy's name. Frequently used to indicate some form of masculinity in the character; if not, expect the character to be very feminine and lament her name.

One commonly offered explanation for a girl having a Tomboyish Name is that her parents wanted a boy.

Many Japanese names are equally appropriate for men and women; tomboyish characters will frequently have one of these. At least two characters named "Megumi" were once boys, for example.

If the character is appearing for the first time, the others may have Pronoun Trouble, where everyone expects this Charlie Somebody person to be a guy, and are surprised when she isn't.

This can become An Aesop if said Charlie Somebody is in a traditionally male-oriented profession; for instance, the Step by Step episode where J.T. immediately dismisses female mechanics, before handing his car over to "Sam", who is apparently the best mechanic in town. The message can quickly get Anvilicious if done more than once in a series. Though you can hardly blame someone if the name means "male"/"man" or include "son" (see: Andrew, Charles. Benjamin).

Sometimes a variation of the Embarrassing First Name. Can potentially lead to Actually, I Am Him, and a good way to help disguise the fact that Samus Is a Girl until the right moment. The Super-Trope is Gender Blender Name.

General

 * Sam
 * There are girls named Sam on Whos the Boss?, Bewitched, Danny Phantom, Without a Trace, Stargate SG-1, Doonesbury, Reunion, Totally Spies, My Sister Sam, Dreamfall and Red Faction (yes, even in video games). Usually shortened from Samantha, in which case it can be taken as an indication that the character wants to have a Tomboyish Name.
 * Sam Carter from Stargate SG-1 also got a Samus Is a Girl moment in her first appearance. When an alien asks what the name means, she replies "My dad wanted a boy."
 * In Quantum Leap, Sam Beckett 'leaped' into a Samantha, who all the other characters addressed as 'Sam'.
 * Without a Trace's Samantha doesn't like being called "Sam" (or at least didn't at first), in no small part because her last name is Spade.
 * Fresh Sam(antha) sighting: Monster Buster Club. (And it's [partially, at least] from the same company as Totally Spies, too.)
 * Metroid bounty hunter Samus Aran could fit the trope as well. Of course, the manual for the original game says she's male (the decision to make her female came about halfway through the game's development), but Samus Is a Girl.
 * Salome Fredericks in Tad Williams' Otherland gave herself the nickname "Sam" to fit in better with the boys online. This fact causes Orlando Gardiner to undergo some angst when he seeks his buddy "Sam" out in Real Life and accidentally uncovers the truth.
 * There's no reason to believe the dog in I Am Legend is a girl until it gets revealed that "Sam" is actually "Samantha."
 * Sam of iCarly
 * One also shows up in American Gods. Shadow asks her if she's a boy Sam or a girl Sam, because they were in the dark when she introduced herself and her voice was deep enough that he thought she could have been a preadolescent boy.
 * The English dub of Medabots had Samantha as the tough-as-nails leader of the Screws Gang.
 * Sam from Danny Phantom. God help you if you dare to use her full name, Samantha.
 * Samanya from Red Faction: Guerilla is normally called Sam for short.
 * In The Perks of Being a Wallflower, Sam is Charlie's love interest/Odd Friendship.


 * Alex:
 * Totally Spies also has a girl named Alex.
 * The Secret World of Alex Mack. Alex is a girl.
 * Law and Order SVU had Alex Cabot and Law and Order: Criminal Intent had Alex Eames. Granted, though, they were named after series creator Dick Wolf's niece or grandchild or something who had the name Alex(andra).
 * Walker, Texas Ranger had DA Alex Cahill.
 * Alexandra Margarita Russo in Wizards of Waverly Place.
 * Degrassi the Next Generation had a lesbian character named Alex.
 * Alexandra Roivas. Likely chosen because Alexander means "I defend"+ "man".
 * Alex on Lost, whose gender was not given until the first season finale. When we first learned of her, Rousseau simply said, "Alex was my child." In season 5, we learned she'd have been Alexander if she'd been a boy.
 * Alex D from Deus Ex Invisible War. The name is purposefully ambiguous so that the player can choose to play a male or female character without needing voice actors to re-record their lines with a different player name.
 * The player's girlfriend in the Neverwinter Nights module series The Bastard of Kosigan is Alexandra de Velan, who prefers Alex and serves as the brains behind an attempt to overthrow the leadership of the most important district of the duchy of Burgundy and have it defect to the French.
 * Alyx from the Half Life Series.
 * When Alex Meade on Ugly Betty had a sex change, she changed her name to Alexis, which makes no sense at all since both names are androgynous. Then again, "Alexandra" wouldn't have the same classic soap connotations.
 * In the Swedish 1950 film Girl With Hyacinths, the protagonist is trying to find out why a young girl killed herself. The only clue is the name of a lover, Alex. At the end of the film, the protagonist is rather stunned to discover that Alex is a woman.
 * Semi-plot point in Building 12.
 * Alex Forrest from Fatal Attraction; feminist criticism points out that the film has her punished for infiltrating environments traditionally reserved for men, with her name itself being an example.
 * Ashes to Ashes has DI Alex Drake. Gene Hunt had been expecting a male DI when he first saw her paperwork.
 * Wen Spencer's fantasy novel Tinker centers around a girl named Alexander Graham Bell. She prefers to go by her (also tomboyish) nickname, Tinker.

Anime and Manga

 * One of the oldest examples is Ryuunosuke Fujinami from Urusei Yatsura, Also one of the original Bifauxnen and a Wholesome Crossdresser to boot. As a rule, -suke is masculine, it's almost like -son (Jacobson, etc) in English. This is due to the fact her father is one of the most extreme examples of 'wanted a boy' in fiction - he forces her to act, talk, dress and pretend to be a boy when she wants to be feminine but can't manage it because of her upbrining.
 * There's a very boyish-looking girl named Edward on Cowboy Bebop, a very odd person who chose her own name (in full: Edward Wong Hau Pepelu Tivrusky IV).
 * According to her father, her real name is Françoise, which is nearly an androgynous name--it's exclusively female, but easily confused with its male counterpart François unless you know how French pronunciation works.
 * At least, it might be. Her father was a bit unhinged and thought she was a little boy when he was re-introduced to her.
 * Last Exile has a girl named Al (short for Alvis), and another named Alistair.
 * Jo on Burst Angel may count as such, especially because she's a Stoic Badass Action Girl and also a mecha pilot.
 * Nagisa in Futari wa Pretty Cure, Itsuki in Heartcatch Pretty Cure and Hibiki in Suite Pretty Cure.
 * Nagisa in Chou Kuse ni Narisou... which turns out to be a blessing, as she spends much of the series disguised as a boy.
 * Makoto and Haruka in Sailor Moon, the latter of whom is actually mistaken for male by much of the cast.
 * The English dub weirdly averted this by renaming Haruka "Amara," a very feminine name which still leads to her being mistaken for a guy.
 * In some supplemental material that preceded the dub, Haruka was called Alex, which made more sense.
 * Another Makoto, this time in Kanon, is called out on having a "boy's name".
 * Another Makoto...kinda the other way. Mizuhara Makoto (japanese name placement =P) from El Hazard. His problem is that he looks just like the rather tomboyish Fatora, who is missing and he has to pose as.
 * Nachi in Mugen Densetsu Takamagahara Dream Saga is a transsexual, but in the parallel world, was born female and still has her masculine name.
 * Fujioka Haruhi of Ouran High School Host Club is mistaken by most people to be male, partially due to her tomboyish personality and speaking style (and short haircut) but also because "Haruhi" is a Gender Blender Name.
 * Gunsmith Cats has a female character named Riff. Not to mention "Larry" Vincent.
 * In Gundam0080, the female pilot for the Gundam is Christina Mackenzie, which commonly is shortened to Chris in-series. The Gundam itself has a Tomboyish Name, Alex, but given that it is a robot, it doesn't invoke the trope.
 * Claes (a common boys' name in Nordic countries) from Gunslinger Girl was so named because her Handler didn't want to make his relationship with her "personal" by giving her a girl's name.
 * Petrushka and Rico are also boy's names, given to two other girls.
 * Oscar François de Jarjayes from Rose of Versailles - her father very much wanted a son and decided to name and raise her as a boy.
 * Elliot Chandler from Mai-Otome 0[[S.ifr]].
 * Baccano! inverts this by giving a major male character the distinctly female-sounding name, Claire. This doesn't make him any less Badass.
 * The Day of Revolution has a brother and sister named Makoto and Mikoto (Makoto is the girl.)...and a Gender Bender protagonist named Megumi as well, though in this case she actually pronounced her name "Kei" when she was a boy. (Isn't kanji fun?)
 * In Fruits Basket, Tohru is our main character. In a flashback, her grandfather wonders about her masculine name, and Kyoko says that Katsuya, her father, picked it to 'bring out her hidden flavor', like adding salt to something sweet to enhance the flavor. Indeed, Tohru is something of a Yamato Nadeshiko (if a bit more clumsy and child-like than the norm). Also  has a man's name.
 * Expounding on this, Tohru is often referred to by other characters with the suffix "-kun", which is usually reserved for males. It's not a hard-and-fast rule, but it's worthy of mention.
 * Actually it isn't reserved for males, "-kun" is used for girls as well to show a degree of familiarity between the formal "-san" and the more familiar "-chan"
 * Ukyo, from Ranma ½, is often mistaken for a boy when people first meet her. Her name doesn't help since it's male (although very old, so people might not know)
 * Ayumu from Life has a male name, which she hates for that reason and thinks doesn't fit her. She has short hair for most of the manga and can easily pass as a boy a lot of the time, but she's actually very feminine.
 * In Pokémon Special, while "Yellow" (Japanese pronunciation, ierou) is by no means a real name in any language, it sounds very masculine to Japanese ears, as "ie" and "rou" are both common suffixes to male names. Fittingly, Yellow goes around masquerading as a boy for the first two arcs she appears in.
 * Seth of Trinity Blood. "Did your parents want a boy?" "I have two older brothers, you'd think they'd had enough."

Comic Books
"Cyclops: Excuse me, I'm looking for Captain Lee Forrester. I heard he was hiring crew. Woman: My name is Lee Forrester -- Aletys to my relatives -- and you heard right."
 * Michael Tree in the Ms. Tree comics.
 * In Archie Comics' Dilton's Strange Science, Teen Genius Dilton Doily invites a fellow prodigy named Danny to his house. True to the trope entry, he experiences Pronoun Trouble when he opens the door and discovers that his guest is a girl named Danni.
 * Come to think of it, Veronica's nickname also fits this trope, as "Ronnie" can be short for "Ronald".
 * Yukio in Marvel's X-Men books. That the ronin good friend of Storm uses a boy's name has led to speculation that it is not her real name. In the limited series Wolverine: Soultaker, her other good friend Logan wonders if her actual name might not be the similar-sounding, but unambiguously feminine "Yukiko".
 * After the death of Dark Phoenix, Cyclops left the X-Men for a time, and decided to apply for employment on a ship. The first person he sees aboard is a pretty young woman.

""Like Butchi or Hanki or Gregori?""
 * In the 1980s Captain America fell in love with and for a time was engaged to Bernie (short for Bernadette) Rosenthal.
 * Parodied in Preacher (Comic Book) with Tommi Ryder, a 'supermodel-turned-lawyer with a dangerous secret' protests that the 'i' makes her name feminine. Amusingly, her (male) love interest's name is Jody.
 * Said Jody also makes fun of said statement.

Fan Fiction

 * In The Show That Never Ends, a Harry Potter fanfic, one of Harry's coworkers is a woman who goes by Diz. It is later revealed that her full name is Disraeli Taylor; her mother was a historian. In fact, her sisters' names are Churchill and Dickens, and her brothers are Tennyson and Darwin.
 * Charlie Duncan of Sapphire Eleanor Rose Suzette De Mont vs. Canon. Her full name is Charlotte, but no one ever calls her that--very fitting of an Action Girl.

Film

 * Sidney of Scream.
 * The titular character in the movie and the series La Femme Nikita.
 * A semi Tomboyish Name starts all the trouble in EuroTrip: The protagonist Scotty freaks out when his German pen-pal Mika Mieke comes on to him. Scotty reacted poorly because he thought Mika Mieke was a male name (along the lines of Mike/Michael), but it's actually a female name, roughly equivalent to Michelle.
 * Watts from the movie Some Kind of Wonderful. At the end of the first draft of the screenplay it's revealed that her first name is actually Susan, but this never happens in the finished film.
 * The Film of the Book Stephen King's IT has a girl named "Daniel Huxton" mentioned as having been killed off-screen by Pennywise the Dancing Clown.
 * In the 1966 film This Property Is Condemned, one of the characters is a young girl named Willie (her parents wanted a boy).
 * In the comedy film But I'm a Cheerleader, one of the main characters is girl called Graham. Fits the stereotype by being a rather butch lesbian.
 * Randall "Randy" Dean, the butch teenage lesbian of ''The Incredibly True Adventures of Two Girls in Love", probably named after Operation Rescue founder Randall Terry by her very pro-life/anti-abortion mother.
 * The Howard Hawks/Leigh Brackett Western El Dorado (1966) has the very tomboyish Joey MacDonald (full name: Josephine), played by Michele Carey.
 * Inverted in Casino Royale 1967 with Peter Sellers' character Evelyn Tremble.
 * Evelyn as a male name wasn't completely unknown in the mid-20th century (most obviously, Evelyn Waugh), but it was pretty uncommon.
 * Arguably, Saavik in the Star Trek movies: there was a definite pattern to Vulcan names in TOS (men are called Spock, Sarek, Surak etc.; women are called T'Pau, T'Pring, T'Lar etc.) and she had a name that fitted the male pattern. (Since then, we've seen Vulcans whose names don't fit either pattern, but at the time...)
 * The character was originally conceived of as male, and wasn't switched to a woman until later drafts. They kept the name, though.

Literature

 * In the Airhead series by Meg Cabot, the main character is geeky high-schooler Emerson Watts. She goes by the name of Em, mostly anyway.
 * George from The Famous Five (shortened from Georgina, in the first book she uses it as part of a Something They Would Never Say ploy)
 * George from the Nancy Drew books, who is proud of her unusual name but is not a Tomboy.
 * Maybe not anymore (since the series has been updated several times), but she certaily used to be. Many fans would go so far as to say she was a lesbian.
 * The character Jo in the book Little Women, who was also a Tomboy, and who makes this Older Than Radio.
 * In Radclyffe Hall's 1928 novel The Well of Loneliness, the lesbian heroine's first name is Stephen.
 * Literary example: Karrin Murphy of The Dresden Files goes by her last name.
 * True in the TV series as well, although there she's a Connie rather than a Karrin. The change was made because Chicago's real-life police department contains an officer whose actual name is Karen Murphy.
 * Haruka in .hack//AI buster.
 * Doctor Who companions in the Expanded Universe include Bernice "Benny" Summerfield (Virgin novels), Samantha "Sam" Jones (BBC Books novels), Isabelle "Izzy" Sinclair (DWM comic strip) and Charlotte "Charley" Pollard (Big Finish audios).
 * This happens quite a bit in the Canon too, with Ace (real name Dorothy), Josephine "Jo" Grant and Melanie "Mel" Bush.
 * In Charlotte Bronte's book Shirley, the title character is given the name Shirley by her father, who wanted a son. This led to the name becoming a female name, and consequently modern readers need to be reminded of this. In fact, the book is the reason Shirley became a popular girls' name.
 * Inverted to amusing effect in Connie Willis's Uncharted Territory. A group of explorers learns they're getting a new intern named Evelyn Parker. The men are all excited to have a new woman in the group. Turns out that in Britain Evelyn can be a man's name, and Ev's parents were traditionalists. Cue disappointment from the men and snickers from the women, especially when it turns out Ev is young, handsome, and single. And straight.
 * The heroine of Robin McKinley's novel The Blue Sword insists on being addressed as Harry. It's not until halfway through the book that her real name is revealed as Angharad.
 * In Laurie King's mystery novels about police officer Katarina Cecilia Martinelli, she determinedly uses the nickname "Casey" on the job. Personal friends can call her Kate, though.
 * Max Ride is a girl. But you sure wouldn't know it if you watched her fight...
 * In one Berenstein Bears book, Sister Bear is being bullied by a classmate named Tuffy. Brother Bear heads off to give Tuffy a piece of his mind, is flabbergasted when he sees Tuffy coming out of the girls' bathroom, and quietly slinks away with her taunting him for not doing anything to her because he can't bring himself to beat up a girl.
 * Scout from To Kill a Mockingbird, which is her nickname - her full name is Jean Louise Finch. Needless to say, you only find that out in scenes where her aunt is trying to put her in dresses or other "formal" settings are happening.
 * Discworld mentions the "oops, we wanted a boy" version with reference to the name Nigella.
 * Also inverted with the wizard Denephew Boot, so called because his 'simple country folk' parents wanted a girl, who they were planning to call Denise.
 * Sets up all the action in Swedish tween book "Dårfinkar och dönickar" (which translates roughly as "idiots and crazies", only the words used are very uncommon). Simone (French female name) is forced to move when her single mother finds a new man. Angry about it, she cuts off her hair. The next day, her new teacher introduces her as "the new boy, Simon". She runs with it.
 * Gabriel Landry in All That Glitters by V. C. Andrews. This appears to be a rather odd Retcon, since the other books in the series name her as "Gabrielle."
 * Jack Starbright, housekeeper to Alex Rider (and the closest thing he has to family after his uncle dies). The first book mentions that Alex wonders what it's short for, but he never asks.
 * Never commented on, but Beldaran in the prequels of the Belgariad. To explain it comes in two parts. The male disciples of the god Aldur get the prefix 'Bel' meaning beloved attached to their names while females disciples get the femenine form 'Pol.' Secondly the name without the prefix 'Daran' is used by her son and several of her descendants as a perfectly serviceable masculine name.
 * Tom Gay (real name Lucinda Muriel) in the Chalet School books. And Joey Bettany, of course.
 * The Malory Towers has both the series' heroine, Darrell Rivers, and late arrival Bill (short for Wilhelmina) Robinson, a very horsey tomboy who has six brothers and who quicky becomes best friends with the somewhat girly girl the Hon. Clarissa Carter.
 * Inverted in Enid Blyton's The Faraway Tree trilogy, the main characters are two sisters and their older brother called Jo - traditionally a girl's spelling. In later editions, it has been altered to Joe.
 * Inverted in Enid Blyton's The Faraway Tree trilogy, the main characters are two sisters and their older brother called Jo - traditionally a girl's spelling. In later editions, it has been altered to Joe.

Live Action TV

 * One genre that is RIPE with this trope involve shows where a female is in an occupation that is typically considered a man's job (female cops, firefighters, soldiers, etc.) One of the most common is contrasting the incredibly girly Mackenzie with the very masculine nickname Mack.
 * The ultimate example would have to be Joey from Dawson's Creek, who played the Tomboy angle straight for the first couple seasons and grew increasingly girly as time went on.
 * This is directly related to the Jo in Little Women, as this character is Joey's (and her mom's) favorite and the reason she's called Josephine like the girl in said book.
 * In the TV sitcom Step by Step, there is Al (short for Alicia).
 * And, as mentioned above, yet another Sam.
 * All of Bryan Fuller's shows seem to have female protagonists with male names/nicknames:
 * Dead Like Me has a girl named George (Georgia), and her sister, Reggie (Regina). Maybe their parents had a thing for feminine names with masculine short forms?
 * In Pushing Daisies, leading lady Charlotte Charles is called Chuck (which is a derivative to Charles meaning "man"...), which is a Tomboyish Name and a Punny Name put together.
 * Wonderfalls has a female main character named Jaye.
 * The female main character on Dark Angel was named Max. This was also an Only One Name.
 * One season 2 episode also had a girl named Ralph.
 * Sisters had a whole family of masculine girl names: Alex, Teddy, Frankie, Georgie, Charley. However, this was not used to indicate masculinity, but that their father always wanted a boy.
 * Devon King, from Midnight Caller
 * In Blackadder II, Nursie is revealed to have the first name "Bernard". She also has sisters named Eric, Basil and Donald. Nursie is not particularly tomboyish, but certainly is insane, so this all could be her imagination.
 * "Bob", however, is tomboyish. Or tries to be. Of course, her name probably isn't really Bob.
 * Jo on The Facts of Life; while Jo-with-no-E is a girl's name, she was mistaken for a boy in the first episode, and is based off Jo from Little Women.
 * Eureka also has a Jo, who gets surly when people call her Josephina.
 * "Doctor Mike," a.k.a. Dr. Michaela Quinn, on Dr. Quinn Medicine Woman There's actually a purpose to this, though. The writers felt it was necessary to explain why the townspeople accept the woman who is coming to be their doctor: they thought she was a man. Communication being what it was, her name was telegraphed to them, as telegraphs were, with no spaces, upper and lower cases, or punctuation. They're expecting "Michael A. Quinn." If her name had been Alice, or something, the viewer is meant to presume they would have cabled back saying "Forget it."
 * Sara "Mac" Mackenzie of JAG, an officer in the US Marine Corps.
 * Reversed in The Young Ones, with a male character named Vyvyan. When they go to the pub, where Vyvyan's mum is working behind the bar, Rick jumps at the chance to ask "Why did you give him a girl's name?" At which point Vyv smashes a bottle over Rick's head.
 * Elliot Reid on Scrubs. But let's not also forget that J.D. usually ends up sleeping with girls with androgynous names, including Alex, Dani, Jamie, Jordan and Kim. Might have something to do with the "lanyards" he made with his bunkmate at summer camp.
 * Kim?
 * Kim can be a boy's name too. Just ask Rudyard Kipling.
 * Jayma Mays played girls named Charlie on both Heroes and Ugly Betty in the same season. Not much chance for confusion, though, since while the UB Charlie, the Heroes Charlie
 * Adding to the heroes example: her full name is Charlene
 * Alex Taylor, a female firefighter on Third Watch who hates being treated differently due to being female.
 * MAD TV airhead Dr. Kylie Johnson was the victim of a typo at least once, or rather at least one of her patients was a victim of such.
 * Somewhat parodied in Extras where Andy Millman goes to Ian Mackellen to audition for his new play. It ends up being a play about homosexual loves, something that is not apparent to him until "Fran" is revealed to be a man. Everyone in the audition room other than Mackellen and Andy appear to have tomboyish names if they are female or girl names if they are male. Things get ridiculous when one of the women in the room is referred to as "George".
 * Winifred "Fred" Burkle from Angel. In one episode, her name causes an old guy in Angel's body to mistake Angel for gay. Refreshingly, Fred is not sassy or conspicuously empowered (that role is taken by a character named Cordelia, itself an inversion of this trope).
 * Alex Drake runs into the Pronoun Trouble variant in the very first episode of Ashes to Ashes; none of her outrageously sexist 1981 coworkers had ever met their new DI before she wound up in their station slightly unhinged and dressed as a hooker for totally plot-related reasons...
 * ADA Alex Cabot, and her replacement Casey Novak, both from Law and Order Special Victims Unit.
 * Power Rangers SPD takes this to absurd levels. Of the two primary female rangers on the show, one is "Z" (short for Elizabeth, well, it's All There in the Manual, if I recall correctly) and one is "Syd" (short for "Sydney"). They were a rather tough Tomboy and Girly Girl duo (with Z as the Tomboy and Syd as the Girly Girl), in some cases tougher than the boys, and Z is extremely tomboyish, Mama Bear regarding Sam  issues aside. It gets worse: On the A-squad, the end credits reveal its  Ranger, female, to be named Charlie, and she's tougher still, and extremely tomboyish in mannerisms while still something of a . She's either the best thing to happen in feminism in the franchise, or a Straw Feminist, depending on who you ask.
 * The Vicar of Dibley had a female vicar called Geri (short for Geraldine), leading to confusion with traditionalist parishioners expecting a male vicar.
 * How I Met Your Mother has Robin Charles Scherbatsky, Jr., who practically embodies the "my dad wanted a son" excuse.
 * South of Nowhere has a Spencer.
 * Skins has Franky, short for Francesca.
 * The live-action segments of Disney's "One Saturday Morning" block originally starred a girl named Charlie.
 * Charlie Benford in Flash Forward 2009 (we haven't been told whether that's short for something more traditionally feminine)
 * Somewhat related: in Mad About You, the characters Paul (male) and Jamie (female) are often referred to as "Paulie" and "James".
 * Picket Fences had officer Maxine "Max" Stewart (Lauren Holly).
 * Aaron Sorkin's shows usually have one of these among the main characters: Dana (Sports Night), C.J. (The West Wing), Jordan (Studio 60 On the Sunset Strip).
 * In Good Luck Charlie, Charlie and Teddy are used as names for girls. It's even lampshaded in one episode.
 * Flashman's Pink Flash is named Lou!
 * Married... with Children: Gary, the owner of the shoe store where Al Bundy works, is a woman. Al spent his first twenty years of work at the shop believing she was a man. (He never met her until being told she'd come to inspect the shop. In fact, he once considered the possibility of Gary not even existing.)
 * Superhuman Samurai Syber-Squad: One of the main characters is a girl named Sydney and she was at least once expected to be a boy because of her name.
 * Sydney Bristow, the main character of Alias. Her friends even call her "Syd".
 * In the BBC series Sherlock, John Watson's sister is called Harry. Having learned her name and the fact that she used to be married to a woman, Sherlock makes an almost accurate series of deductions regarding John's "brother".
 * In Full House, there is DJ, who is the oldest daughter but the abbreviated initials are at best gender-neutral, if not leaning towards being boyish-sounding. It stands for Donna-Jo (not Joanna, not Josephine, just Jo).
 * Dylan from The Secret Life of the American Teenager
 * In an inversion, The Mentalist, Patrick Jane, is generally referred to as Jane.

Music

 * A rather famous inversion: Johnny Cash's Boy Named Sue. The original poem was written by Shel Silverstein.

Newspaper Comics

 * In one Homer, the Reluctant Soul strip, Homer (who has been incarnated as the daughter of an Irish couple en route to Ellis Island) is about to be given a Tomboyish Name suggested by her Father... but her Mother, being more sensible, names her Honor (Homer's name during a female incarnation). Honor thinks to herself, "Drat. I kind of liked 'Fisk'".

Professional Wrestling
"Bobby Heenan: Mike?! What's her brother's name - Sally? Gorilla Monsoon: I don't know... maybe her father wanted a boy. Bobby Heenan: Looks like he almost got one..."
 * WWE wrestler Mickie James is a former Women's Champion. Granted, this is wrestling, and stranger things have happened than a man holding a women's belt, but she is a woman.
 * Former WWE ring announcer Mike McGuirk (real name Michelle).

Theatre

 * In the musical Once Upon a Mattress, Winnifred tells the Prince he can call her by her nickname. He guesses, "Winnie?" She corrects him, and a minute later, he's summoned everybody to hear his "Song of Love": "I'm in love with a girl named Fred!"
 * The title character of the George M. Cohan musical Billie. She and her show would be completely forgotten if George M! hadn't reused the title song, in which she divulges that her parents had wanted a boy.

Video Games

 * Reversed (sort of) in the Dating Sim X-Change Alternative, with main character Kaoru. Since he is rather short of stature, rather pretty and... not blessed down below, it seems a little cruel of his parents to have given him a girl's name. Later on, it's revealed that he's genetically intersexed, so it's assumed his parents were just hedging their bets. Meanwhile, he's been gender bent...
 * The Bifauxnen bouncer/bartender from Art of Fighting and The King of Fighters goes by the name of "King" (no last name).
 * Ken Marinaris in Zone of the Enders: The 2nd Runner but her large breasts make it clear that she is very much a woman.
 * Atlas, the controller of Model F from Mega Man ZX Advent, is actually a girl.
 * Also inverted in the same game; Thetis, who shares a name with Achilles' mother in Greek lore, is a male who controls Model L, the only female biometal.
 * The first Ratchet and Clank game has three mechanics who can upgrade Clank. Their names are Al, Bob, and Ed. Guess which one's the girl?
 * After acquiring all eight badges in Pokémon Ruby and Sapphire or Emerald, a player can find an older women named Jay on the second floor of Meteor Falls.
 * Inverted in the Viridian Gym in the Pokémon HeartGold and SoulSilver versions, with male trainers named Arabella and Bonita.
 * The female protagonist of Crystal is called "Kris", which sounds like "Chris". It's never specified in the games if this is short for anything, though a few adaptations put it as short for "Crystal".
 * Suikoden IV has Wendel, who gets mistaken for a guy by Nico, your ship's lookout. This is notable mainly because Nico's vision and perception are praised almost every time the subject comes up -- in fact, Wendel has been trying to become Nico's apprentice because of his fantastic eyesight.
 * Ridley Silverlake from Radiata Stories. When Jack runs into her in his Radiata Knights trial at the beginning of the game, he's dismayed to learn that she's a girl.
 * Since there were several "Makoto"s mentioned in the Anime & Manga section, there should be at least some mention of the one from Street Fighter III 3rd Strike. Her VA is also named Makoto, as well.
 * And yet another Makoto, from the IdolM@ster series, who becomes an idol in order to find a more feminine side of herself.
 * And Makoto from Blaz Blue! Maybe this one's gaining ground as a girl's name.
 * Kairi. Though it is technically a gender-neutral name in Japan, it is really rarely used as a girl's name. Yet, the main Damsel in Distress of the game Kingdom Hearts has this name, and she displayed a somewhat tomboyish personality during the periods in which she was conscious.
 * For a male example, Axel's true name before turning into a Nobody was Lea.
 * Actually, it was just a variation of "Lee," which is usually masculine.
 * Harold Berselius of Tales of Destiny 2, who is in fact often mistaken as a man by people who have yet to meet her.
 * And then there's Corrine, the summon spirit in Symphonia. Corrine is typically a female name, and the spirit itself has a high-pitched, feminine voice. However, there are some instances Corrine is referred to as male, . This is even more confusing as what Corrine's relation to   is never agreed upon in Symphonia's many iterations.
 * In Mass Effect 2, one of the teammates that Shepard must pick up is a convict named Jack. When you release Jack from cryo-stasis, the other party members are surprised to find a shaven young woman of a smallish frame covered in tattoes and little else... Who proceeds to single-handedly go on a Roaring Rampage of Revenge across the ship and tear it to pieces.
 * The original Mass Effect also has Ashley "Ash" Williams.
 * One of Mana Khemia 2's playable characters is the tomboyish Et, short for Etward. As a child, she decided her little brother's name was better and forced him to switch with her. The fact that this typifies his relationship with her and he grew up as Enna (short for Ennarcia) is only the start of the poor kid's problems.
 * Chromie from World of Warcraft is a bronze dragon who preferred lesser form is a female gnome. While most female bronze dragons have names ending in "ormi" her full name is Chronormu, and "ormu" is the ending associated with male bronze dragons. This led many to speculate that she was in fact a male dragon who preferred to take femmale shape (which, given the game, would be wholly appropriate) but Word of God eventually clarified that she just had a Tomboyish Name.
 * Elias from the original Panel De Pon.
 * Yuugi Hoshiguma from Touhou. The name means "a game", as in chess or go (or cards), and it has a masculine tone to it. She looks and acts masculine too, and in fan works is usually contrasted against the girly Green-Eyed Monster Parsee for effect.
 * Shou Toramaru. Not only is her given name masculine, her surname uses a male suffix!
 * Grand Theft Auto brought us a female disc jocky named Toni.

Visual Novels

 * The Fujibayashi twins, Kyou and Ryou, in Clannad.
 * This was actually a plot point in the final case of Phoenix Wright: Ace Attorney: Justice For All.

Web Comics

 * Three of the four (formerly male) main characters in Cheer! have gender-ambiguous names (Sam, Jo and Alex), even though these are all different from their original male names.
 * Parodied in Schlock Mercenary: when Captain Tagon decides to hire a new medical officer, the first thing he notices are her rather large physical assets. He only notes that her name is 'Edward' (due to her incredibly stupid parent's poor choice of names) after deciding to hire her (but before actually looking at her professional credentials). To be fair, when she was conceived, her parents (who could not legally have natural-born children due to their deficient intelligence and appearance) had her genetically engineered to have a Nobel-laureate brain in an exotic dancer's body.
 * Parley from Gunnerkrigg Court isn't very tomboyish at all, but her first name is George. She's deeply embarrassed by this name, although there's a pretty good story behind it.
 * Misfile has Ash Upton. Word of God has it her full name (at least in this timeline) is Ashley, which isn't much of an improvement. Of course she used to be a boy anyway.
 * Ariel from Drowtales, ironically, she is send to a boys school (because of exceptional circumstances) and one of her (male) classmates is more effeminated than her.
 * Wapsi Square has Bud, which is luckily a nickname. Her actual first name is Acacia, which doesn't shorten well, so she goes by a shortened version of her last name (Budur).
 * In Two Guys and Guy, a webcomic featuring Two Guys and a Girl, "Guy" is the girl.
 * In Two Guys and Guy, a webcomic featuring Two Guys and a Girl, "Guy" is the girl.

Web Original

 * Billie Wilson, who actually is a Tomboy, in the Whateley Universe. Since she also hangs with Toni Chandler and Nikki Reilly, this could cause problems if they weren't all hot superheroines. And Sam Everheart, extremely-competent female security officer at Whateley Academy, with her own secret to hide.
 * Not really a true example since all four of these characters are former boys who chose feminized versions of their former male names or nicknames as the case may be.
 * Codex from The Guild has the real name Cyd. She specifies that it's not short for anything.
 * from Red vs. Blue. With a logical reason for the name. (Somewhat.)

Western Animation

 * Frances "Frankie" Foster in Foster's Home for Imaginary Friends. Similarly, Frankie Stein in Monster High.
 * Rocket Power has a girl named Reggie (short for Regina).
 * You mean Reggie wasn't her legal name? Huh; that's weird; I knew a girl whose legal WAS Reggie.
 * In Disney's Famous Five On The Case, George's daugheter is named Jo (shortened from Jyoti).
 * The Secret Keeper on Batman Beyond was also named Max (short for 'Maxine').
 * The leader of the Guardians in W.I.T.C.H., Will Vandom, is a girl like the others. Depending on the source, it's short for Wilma, or Wilhelmina.
 * Subverted in Recess with Spinelli, a tomboy who goes by her last name because she's embarrassed about her "girly" first name, Ashley. It's especially "girly" on this show because there's a club consisting entirely of girls with this name (who seem to equate the name with popularity), and one episode was about the consequences when the Ashleys found out her real name and forced her to join their club. Ironically, Ashley was once considered a boy's name (such as in Gone With the Wind), and some well-known guys do have Ashley as a name (like Ashley Cole). Sometimes, they go by "Ash".
 * Sam and Alex from Totally Spies. However Alex is the only Tomboy.
 * Izzy from Total Drama Island, which may or may not be short for Isabella. Revenge of the Island has Jo, who is a straight-up tomboy, disliking anything even remotely girly and is often confused for a guy by Dumb Jock Lightning.
 * In an episode of What's New Scooby Doo, the guys on the gang are excited about meeting a pair of male roller-coaster designers called Chris and Terry, while the girls are unimpressed...until they turn out to be sisters called Chris and Terri.
 * In an episode of Batman: The Animated Series, Poison Ivy appears to have gone straight and gotten married. Batman observes some heartwarming interactions between Pam and her stepsons, Chris and Kelly, but realizes something's up when Robin says he knows the "husband" and his daughters.
 * King of the Hill: Kahn, Hank's Asian neighbor, named his daughter after him. Kahn Junior told Bobby that was because he wanted a son. However, she often goes by Connie.
 * Applejack, from My Little Pony Friendship Is Magic. It sounds like she has a boy's name, which led to a considerable amount of gender confusion back in G1 where she had a low pitched voice.
 * Also, Rainbow Dash. Her name sounds feminine, but is often shortened to just "Dash", which sounds somewhat masculine.
 * Inverted with Mandark from Dexter's Laboratory, whose real name is "Susan".
 * Michelanne "Mike" Mazinsky.

Real Life

 * Actresses with Tomboyish names include Billie Piper, Hayden Panettiere, Michael Learned, Glenn Close, James "Jamie" King, Jamie Lee Curtis, Glen Close, Christopher Norris andSean Young.

 * Michael Learned, from The Waltons.
 * Her birth name was "Michael Michele Williams". Even better: she was named after her mother's best friend, a woman named "Michael."
 * Barack Obama's mother, who went by her middle name Ann, was named Stanley after her father. Probably where this reporter's confusion came from.
 * Anne Rice was for some time Howard Allen O'Brien.
 * A bizarre twist on this trope: over the last hundred years, Ashley has gone from being a male name to a female one. (Not to anyone who has seen Gone with the Wind)
 * As has Meredith, though that could be more the transition from Wales to the U.S. than time...
 * Not to mention Madison; the name's popularity as a female name has been credited to its appearance as a name chosen by the mermaid in Splash.
 * As mentioned above, Shirley was a distinctly male name until 1849, when a book came out featuring a female protagonist who had been named Shirley (because her father had wanted a boy), thereby popularizing the name for girls instead.
 * Andrea is a very common men's name in Greece (Shares a root with Andrew) and a not-very-common-but-not-unheard-of girl's name everywhere else. The root of the name? Greek for "man"...
 * "Lee" and any names that end in "-lee" or a variation thereof were at one point exclusively male.
 * When Howard Hawks hired Leigh Brackett to co-write the screenplay for The Big Sleep (with William Faulkner), he was surprised at their first meeting to find the writer he hired was a woman.
 * There's a well known human rights lawyer in Britain called Gareth Peirce, although she changed her name legally. "Gareth" was originally her middle name.
 * Born a Stephanie, Stevie Nicks has gone by Stevie for most of her life. She had difficulty pronouncing her name when she was young, and the nickname stuck.
 * An inversion occurs in the nickname of a West German striker who played in the 1966 World Cup final, Lothar "Emma" Emmerich.
 * Brett Anderson. No, not the guy who sings for Suede, but the girl who fronts The Donnas.
 * Porn actress Daryn Darby.
 * Former White Zombie bassist Sean Yseult.
 * Actress Jennifer Jason Leigh. Her first name isn't, but her middle name definitely is.
 * Cayman Ilika.

 * ESPN Sportscenter anchor Chris Mc Kendry is a woman as is MSNBC anchor Chris Jansing.
 * Chris Evert counts too
