The All-Concealing "I"

First-person narration has something of a dual nature. On the one hand, it carries an inherently tight coupling to the protagonist. As such, it's a great way to really get inside their head, showing the reader exactly what they're thinking and why.

On the other hand, the structure of English grammar also makes it easy to use a first-person narrative to avoid mentioning basic facts about the narrator. These facts may include the gender, the name, and even the very identity of the narrator. This is a frequent way to achieve a Tomato Surprise.

The extent to which this is possible or necessary is very language-specific, especially when the datum to be concealed is a gender. For example, Japanese generally has separate male and female first-person pronouns, so Gender Neutral Writing isn't much easier in the first person than in the third person. In fact, because people outside of family and friends are often referred to by last name alone, it can be easier to surprise the reader about the gender of a third person than it would be to surprise the reader about the gender of the narrator. Similarly, many languages (notably both Romance and Slavic languages) have enough grammatical gender markers other than pronouns that this trope becomes a practical if not a definitional impossibility. Conversely, a number of languages lack gender in the third person, permitting gender-neutral writing without resorting to first person.

In principle, you could accomplish the same thing using Second Person Narration, although you don't see that done very often.

Comic Books

 * The first miniseries for the comic book Shadowhawk was written in first person to both keep the hero's identity secret even from the reader and to immerse the reader further in the story. It was a great success, but future issues spoiled it by switching to third person.
 * About halfway through the graphic novel Enigma, the narrator reveals he's a character within the story. To this point the narrator commented on events with an unusually sardonic and cynical eye, questioning his own perceptions of things and upending the reader's expectations, so it felt very much like he was an extra character in the story, though not necessarily integral to the plot. That changes with this reveal, and the narrator himself is not shown until the very end.

Commercials

 * This Australian commercial.

Fan Works

 * This is used in the Fanfic Sleeping with the Girls to conceal the protagonist's name as the work is an affectionate parody of a Self-Insert Fic.
 * Used in the Pokémon fanfic Ashs Return to maintain for the readers the Ontological Mystery caused by the narrator not remembering his/her own identity.
 * Used in the My Little Pony: Friendship Is Magic fanfic, My Little Dashie. We know the protagonist is a young man, but that's about it.

Film

 * The Message is a 1976 film about the life of the prophet Mohammad. Since Islam forbids images of him, the director shot all the scenes containing him from the first person.
 * Fallen:

Literature

 * Book 4 of 2666 by Robert Bolano runs on for about 40 pages before it starts to drop subtle hints that the main character Oscar Fate is . Because much of the story up until that point has dealt with it lends some events a new significance and explains why Oscar went mental at another character's comment earlier. Although he is full mental anyway.
 * In Toni Morrison's short story Recitatif the narrator, Twyla, reminisces about her childhood best friend, Roberta. Significantly, since the story is set during the height of the Civil Rights Movement, one girl is black and the other white, but the narrative never reveals which.
 * The Culture novels by Iain M. Banks have several examples:
 * In The Player Of Games, first-person narration is used to disguise the identity of the narrator.  The Reveal is the very last word in the book.
 * Use Of Weapons manages to achieve this  without the wording seeming awkward. Although the drawn-out nature of The Reveal in this case almost completely counter-acts the use of this trope if you had figured it out 100 pages earlier.
 * Though not a Culture novel, The Wasp Factory uses a First Person Narrator to avoid mentioning that . Something of a subversion though, as thanks to an accident (and some severly messed up parenting), the narrator is unaware that this is the truth.
 * In Blood and Iron by Elizabeth Bear, one of the main characters magically gives up her name. From then on, all the sections from her perspective are written in the first person.
 * Bone Dance by Emma Bull uses first-person narration to conceal the fact that the main character is.
 * In Sarah Caudwell's Hilary Tamar mysteries, the gender of the title character / narrator is never specified.
 * The secret concealed by this trope in Agatha Christie's The Murder of Roger Ackroyd provoked considerable outrage, including the possibly apocryphal reaction by the Queen, "Oh, Agatha, how could you?"; in this book, possibly the pinnacle of Christie's mystery-writing career, the narrator and de-facto assistant to the detective.
 * In Marele Day's The Life and Crimes of Harry Lavender, first person narration conceals the fact that the Hardboiled Detective protagonist is a woman.
 * At least one Goosebumps used this for effect. "My Best Friend Is Invisible" waits until the titular character is made visible to reveal that the
 * In The Gone-Away World by Nick Harkaway, first-person narration is used to conceal the fact that the protagonist, because he's actually.
 * Ralph Ellison uses this device in Invisible Man to conceal the narrator's name and any physical description of himself apart from the fact that he is a black male.
 * Most of Thierry Jonquet's La Bête et la Belle (The Beast and the Beauty, literally) is narrated by, but it's only suggested through subtle clues.
 * The Outsider by H.P. Lovecraft..
 * It has also been made into a flash game -link here- for those who prefer a more visual approach.
 * Beatrice Mosionier's Spirit of the White Bison. The title character is also the narrator, and there are only two small, easy-to-miss hints in the novella that it's actually a cow bison. Yup, the narration is quite interesting.
 * Rather poorly done in E. Nesbit's The Story of the Treasure Seekers, but justified as the narrator him/herself is a child and is only concealing their identity as a game for the reader.
 * Although Salman Rushdie's The Satanic Verses is written mostly in the third person, it does have a narrator who intrudes on a few occasions. He is never explicitly identified, but it's heavily implied that he is.
 * In Louis Sachar's There's a Boy in the Girls' Bathroom, Bradley does a report on a book written in the first person, and only realizes while writing the report that the narrator never gives a name or gender.
 * The Thief by Megan Whalen Turner is one of the more successful examples, managing even to conceal that anything's being hidden at all. The best part about it is, all the clues you need to figure it out are barefaced and obvious. But because you don't realize there's any secret at all, you don't pick up on the fact that they are clues until The Reveal.
 * In The Time Machine by H. G. Wells, first person is used to conceal the main character's name when he's telling his story to the narrator in flashback. The narrator also conceals his identity in third person by just calling him the Time Traveler.
 * Bernard Werber plays with this in some of his short stories (L'arbre des possibles -The Tree of Potentialities). One narrator turns out to be ; another is.
 * Illuminatus! has occasional bits of first-person narration; at the end of the book, many of them are revealed to be from the perspective of . Maybe. You know it's a Mind Screw when the protagonists instantly start commenting why The Reveal makes no sense, and suggest more outlandish theories, instead.
 * Hardboiled Wonderland And The End of The World by Haruki Murakami has an variation on this that is possible thanks to a quirk of the Japanese language. In the original the identity of the narrator(s) is concealed by using "watashi" in the main story and "boku" in the other. The English translator felt "boku" to be more intimate and used the present tense for that section.
 * In Bernard Beckett's novel Genesis, the narrator at first appears to be a female, human student of history. The book details the 'history' of her era (22nd and + centuries) and as her recount of history goes on, we discover that, in short,
 * The Elegance Of The Hedgehog by Muriel Barbery is written in the first person from two different perspectives. For a while, at the beginning, this means it's not entirely clear whether the two perspectives are two separate people or the same person at two different stages of life (unless you read the inside cover flap, at least). Even after this is resolved,
 * Chasm City by Alastair Reynolds uses first-person narration to conceal
 * Sally's brother in The Cat in the Hat narrates the story, making some small children insist that his name is actually I.
 * According to the live-action movie starring Mike Myers, the boy's name is Conrad, and in The Cat in the Hat Knows a Lot About That!, the boy (who is now black via Race Lift) is instead named Nick.
 * Bad Monkeys, by Matt Ruff, makes use of this. The story-within-a-story, first-person narration by the main character is done to hide
 * Isaac Asimov used this trope in many of his short stories in order to illustrate that parts of humanity (and life in general) that are automatically ascribed to one type of being can fit with another if you just give it a chance.
 * One short story has a surgeon trying to talk his patient out of replacing his failing heart with a completely artificial metal construct, as opposed to an organic replacement instead. He speaks at long length about retaining personal identity and how this will be but one more step in blurring the lines between humanity and robot, and even though he has nothing against either humans or robots, it is important that they remain separate and not try to merge. It is only in the last paragraph that we learn that the surgeon, who argued long and hard against the patient becoming closer to a robot,
 * Another Asimov story involves time travel, and is narrated by the assistant of the group of scientists who invent the time machine, and is also  He then takes measures to avoid changing this future.
 * Yet another Asimov story (written at the height of the Cold War) features two astronauts sent to repair a malfunctioning satellite. About halfway through the story, the narrator is revealed to be a woman —and Russian, to boot. This is entirely incidental to the story, but it underscored Asimov's beliefs in gender equality and human cooperation.
 * In the book Someone Like Me by Elaine Forrestal, it is revealed (or rather confirmed, as there are hints throughout) at the very end that the narrator Tas Kennedy is.
 * In Orca, Kiera the Thief guest-stars as the narrator. And, in the process, expertly manages to cover up the fact that . Vlad's Unreliable Narrator tendencies have got nothing on that. (It makes sense in-universe; she's narrating to Cawti, who doesn't know her secret, so naturally she has to tell the story in such a way as to conceal it.)
 * The first-person narration in Neil Gaiman's Holmesian pastiche "A Study in Emerald" is used to conceal the fact that
 * The Printer's Devil by Paul Bajoria will surprise the crap out of most readers about halfway through when the narrator reveals, well, something that shouldn't be that surprising, if you think about it. Especially in the context of this trope.
 * Jonathan Barnes' The Somnambulist doesn't reveal ANYTHING about the narrator other than the fact that he is male, until near the end.
 * The Turbulent Term of Tyke Tiler by Gene Kemp is written so as to make it natural to assume that Tyke is a boy, thanks to Gender Neutral Writing and her tomboyish character.
 * Doorways in The Sand, by Roger Zelazny, pulls this trick with a reveal coming only at the last sentence:.
 * The Repossession Mambo, by Eric Garcia, is written in the first person. You may not notice until it is mentioned in the Making Of essay at the back of the book.
 * The narrator of The Best Christmas Pageant Ever never gets a name, and it's only apparent she's a girl because her best friend is one, and she says something about not wanting to be Mary in the pageant.
 * Bill Pronzini's Nameless Detective series has used this for 36 books and counting.
 * In First Among Sequels in the Thursday Next series.
 * In the novel "What I was" by Meg Roseff, we don't find out the name of our protagonist, a 16 year old boy, until near the end of the book, where Finn uses his name as a disguise:
 * In the short story "Just Good Friends" by Jeffrey Archer, the female narrator who goes home with a guy she met in a bar turns out to be.
 * In The Left Hand of Darkness, one essay that ruminates at length on gender politics, and the effect that a lack of gender has had on the people of Winter, finishes with the off-hand revelation that the author of the essay is
 * In People Of The Book, most of the flashback narrations are in third-person, as opposed Hanna's unifying narration in first person. That is, up until the first-person, Muslim,  illuminator of the Sarajevo Haggadah.
 * In the novel Then We Came To The End, the whole thing is written in the first person plural. The narrators are positioned as people who work in the office in which the characters work, but it is never made clear whether any of the named characters are included in "we". It is surprisingly effective.
 * Joanne Harris's Gentlemen and Players is narrated by two characters, one the protagonist and the other the antagonist. The antagonist's first-person narrative effectively hides the character's name and identity
 * This is common practice in the more psychological breed of mystery thrillers, where it is used to provide brief glimpses into the mind of the killer without providing identifying characteristics such as name and gender. The Various Haunts of Men by Susan Hill is a good example.
 * In the Jorge Luis Borges short story "The House of Asterion," the eponymous, unworldly prince describes his isolated life, lack of education, and limited social interactions. His terminology and allusions become increasingly bizarre. He expresses longing for a prophesied saviour who will one day come to free him from his lonely, infinite house.
 * Brooklyn Burning by Steve Brezenoff uses this and Second Person Narration to hide the genders of the two main characters.

Music

 * In It's a Mistake by Men At Work, World War III (accidentally) breaks out and shortly thereafter the victorious military has "got the bad guys on the run". In the next verse we learn that the victorious military has just captured Ronald Reagan.
 * The music video for Smack My Bitch Up by Prodigy is shot from the first-person perspective. The twist comes in the end, when we learn the hard-drinking, hard-partying, drug-addicted, violent womanizing protagonist is.
 * On a lighter note, the song "Christmas Isn't Christmas Without You" seems like a typical jazzy song about a woman who's sad that the man she loves can't be with her on Christmas Eve. In the end, it's revealed that the woman is Mrs. Claus.

Tabletop Games

 * Shadowrun:
 * In the sourcebook Aztlan by Nigel Findley, the material is interspersed with a chat log between various parties who can be identified only from details included in their conversations (e.g. 'the Big D' is revealed to be the dragon Dunkelzahn).
 * Orange Queen, a Shadowland site regular whose first-person comments appear in various articles throughout the sourcebooks, is eventually revealed to be.
 * Rare second-person example: In the Kalamar D&D setting, the main holy book of the god of pain is an account of someone lost in an icy wasteland, trudging barefoot over sharp rocks and then falling through a frozen lake. It's written in the second person, apparently to make it creepier.

Video Games

 * Adam Cadre's work is full of this.
 * 9:05 lets you fulfill the daily life of a salaryman
 * Shrapnel combines this with Time Travel to set the player as
 * Photopia once again pulls the You Never Asked thing to reveal
 * Text adventures in general will give you evasive responses to "examine me" such as "You look the same as you always do." Or "You look like yourself."
 * Slouching Towards Bedlam deliberately avoids the second person pronouns that are traditional in Interactive Fiction... but you might not notice at first. It's an eerily subtle symptom of something much bigger going on with your character.
 * Umineko no Naku Koro ni:
 * In a variation, the original visual novels regularly switch between first- and third-person in a rather confusing way. The first-person sections are narrated by the protagonist -- usually—but it's not until later that we find out the third-person sections are also being narrated- by the Game Master, who is always interested in tricking you. It can sometimes even be hard to spot when the POV switches. Unreliable Narrator ahoy!
 * Episode 6 has a case of this. The difference from the series' normal use is that there are no sprites showing which character it is and the character in question is locked in a room from which s/he can't get out of. It quickly becomes very creepy.
 * In the visual novel Ever 17, the player can choose to play as either Takeshi or the Kid. You play with a first-person POV from the selected character, meaning you can only see Takeshi when playing as the Kid and can only see the Kid when playing as Takeshi. Taking it even further, once you've made the choice, lines spoken by your controlled character are not voice acted, denying you even the knowledge of what you sound like. All of this is crucial to the final act's Mind Screw plot twist:
 * The Marathon series has an odd variation of this - you play a Heroic Mime character that is treated like a tool by most other main characters, and as such the only dialogue you get is overheard conversations in which you aren't mentioned or someone talking to you giving you orders. Aside from a short, vague prologue in the manual there is no background for your character, and he is never seen. Plenty of hints are in the game, with mention of military cyborgs and soldiers made from the reanimated dead, but arguments still go on as to what exactly he is.
 * In Silent Hill: Shattered Memories, the first-person therapy sessions are actually
 * Done beautifully in one of the text sections in NieR. One villager's dream is written like a Lovecraftian classic, sanity slipping away as you trek through halls of wanton gore. Once you navigate your way out of the dungeon, the narrator mentions their  but he hides it well."
