A Long Running Book Series, beginning in 1927, for kids and teens created by the legendary Stratemeyer Syndicate under the pseudonym Franklin W. Dixon. They follow the adventures of Frank and Joe Hardy, a pair of brother detectives. Frank is the logical, calm one, and Joe is the more impulsive, instinctual one. The series (alongside their Distaff Counterpart and frequent Crossover partner Nancy Drew) invented or popularized most of the Kid Detective tropes.
Originally created by the Stratemeyer Syndicate, a prolific group of ghostwriters under the direction of Edward Stratemeyer (and his daughters, who took over when Edward died in 1930) that put out many successful children's books. Canadian writer Leslie McFarlane was the original writer of the first 16 books, writing them only to pay his bills and feed his family (getting ~$100 US for each book, with no royalties), and dreaded having to write the books (referring to the books in his diary as "the damn juveniles"), and by the mid-30s other writers began to write the books as well (such as John Button, whose books are infamous for their use of sci-fi elements, inconsistencies, and strange plots), leaving McFarlane free to forget about the books and write his own stories.
In the late 1950s until the early '70s, the first 38 books were revised and rewritten to update the stories (terms like "chum", "roadster", etc.), remove politically incorrect terms and stereotypes ("Negro", "swarthy foreigner", "Chinaman", "colored", etc.), as well as shortening the books from 25 chapters to 20 chapters. Newer books were also made, with the "original" series coming to an end in 1979 with #58. The original editions can be recognized by having dust jackets and plain brown (and later, tan "tweed") covers; the revised versions, beginning in 1961, have the cover picture printed directly on the book to better withstand being used and abused by kids.
After the books were acquired by Simon & Schuster (which took control of Grosset & Dunlap in the 70s after a lawsuit), the series was continued as "Digests". Later on, the Darker and Edgier Casefiles series was added and ran concurrently with the Digests. Both series have since been discontinued, the Casefiles in 1998 and the Digests in 2005. The series has since continued under the Undercover Brothers subtitle, which reinvents the brothers as agents working for an all-teen secret agency; there is also a corresponding graphic novel series.
The Hardy Boys have also appeared on TV several times, originally courtesy of a serial running on the Mickey Mouse Club. They shared a show with Nancy Drew on ABC in The Seventies, and had a series of their own, produced by Nelvana, in the The Nineties. They also (whew!) had a 1969 Saturday Morning Cartoon series.
- Aloof Ally: in the Casefiles series, the Gray Man and, by extension, the Network he works for.
- Animated Adaptation: CBS had a cartoon version which ran 34 episodes from 1969-1971.
- Big Eater: Chet Morton, but both Hardy Boys seem to qualify as well. Joe sometimes rivals Chet's, and Frank, well...
Callie: We polished off a huge pie at Mr. Pizza's. And I only had two slices.
- Born Detective
- Brains and Brawn: respectively, Frank and Joe themselves are often compared to each other like this.
- Chekhov's Hobby: Chet Morton and his loads of hobbies that seems to change for each book.
- Frank and Joe are both guilty of this too.
- City of Adventure: A lot of stuff seems to happen in good ol' Bayport. Also averted, since the brothers travel all over the world when they stumble into mysteries.
- In the Hardy Boys, it's slightly justified. Bayport was a port city (duh), so some smuggling was expected. It makes less sense in Nancy Drew's hometown River Heights (although both were suburbs of cities which were known for mafia activity, New York and Chicago.)
- Choose Your Own Adventure: The "Be a Detective" series, which ran for six books and was a Crossover with Nancy Drew.
- Classy Cat Burglar: Charity in the Casefiles. Fiona Fox in the '88 Super Mysteries.
- Cliff Hanger: One almost every chapter.
- Cool Bike: In the most recent series of books
- Cool Boat: the Sleuth in the original series. Who knew that a term for a detective would be a good name for a boat?
- Their friend Tony's boat, the Napoli, also qualifies, as it's used to help them out on a number of occasions.
- Cool Car: Several of them
- Subverted in the original books, where their car was described by Chet as looking "like a million dollars but drove like thirty cents", and can barely make 15 miles an hour.
- Crossover: With Nancy Drew in the "Super Mystery" series and Tom Swift in the "Ultra Thriller" books.
- Darker and Edgier: The newer Hardy Boy Casefiles series. Iola Morton, Joe's long-running girlfriend in the original series, is blown up by terrorists shortly before the opening scene of the first book.
- Not to mention that some cases would place tension between the brothers, which would often lead into not-so-friendly brawls between them. Later, it also modifies their relationship with the police (which is scarcely a problem in the original series), with an Ascended Extra of sorts in Con Riley as the only officer that takes their skills seriously. And then there are the Assassins, the terrorist group responsible for Iola's aforementioned murder, and are also the most frequently recurring villains in the series who, well...do exactly what you might expect.
- The original edition of "The Sinister Signpost" features a vaguely middle-European villain named Vilnoff who tries to destroy Bayport, and kills himself via electrocution to avoid arrest.
- Dude in Distress: Both of them, also Fenton and Chet on occasion.
- Doppelganger: In a Casefiles book, body doubles of the boys are made once they're captured. They play Spot the Imposter. It turns out Iola kept a diary, so when Joe asks her questions, in standard trope fashion, "only she would know the answer to"...
- Eagle-Eye Detection
- Fat Best Friend: Chet Morton is the best friend of The Hardy Boys, and has been described as fat, plump, chubby, stout, heavy-set, etc. He has a huge appetite, and vacillates between types A, B and C as the plot dictates.
- Friend or Foe
- Girl of the Week: Happens pretty often in the Casefiles series, although they usually tended to go for Joe; the ones who would have eyes for Frank would have to be let down gently in the end because he's with Callie, of course.
- Guile Hero: Especially at the Casefiles books when they are almost always have to fend for themselves to outwit their enemies. Frank in particular can be a very efficient chessmaster, but even Joe can pull a few tricks of his own.
- Hard Head
- Have a Gay Old Time: Done intentionally by the most prolific of the authors, as a way of injecting humor into a job he didn't care for much. See more details here.
- South Park picked up on it.
I'm getting a raging clue right now.
- Kid Detective/Amateur Sleuth
- Live Action Adaptation: The Mickey Mouse Club adaptation in the 1950s; The Hardy Boys Nancy Drew Mysteries, which ran from 1977-1979, and the short-lived The Hardy Boys in 1995.
- There have been rumors for a long time about "The Hardy Men," a live-action movie starring Ben Stiller and Tom Cruise as the Hardy Brothers as adults.
- Long Running Book Series
- Made of Iron: Joe, who takes most of the punishment due to him being the "athletic" one.
- The Meddling Kids Are Useless: Former Trope Namer, due to the fact that in the early books, the Hardy brothers would often find out who did what, but at the same time the police were doing the same. Essentially, the had grand adventures but didn't affect much in the long run. This was later changed.
- Not Now, Kiddo: The Hardys met with this in a lot of the early books. Eventually, Chief Collig and Con Riley figured out they should probably listen to them once in a while...
- Odd Couple
- Put on a Bus: The majority of the Hardy's circle of friends have slowly faded away as time has gone by. Chet is still a regular, Biff Hooper and Tony Prito make rare appearances, but Phil Cohen and Jerry Gilroy seem to have completely disappeared.
- Recycled in Space: The 1969 animated show featured the Hardy Boys...as a hip groovy rock band!
- Sibling Team
- Spin-Off: There have been several:
- The Hardy Boys Casefiles: Darker and Edgier and Hotter and Sexier series designed to appeal to teen audiences by removing the previous roadblocks of the parent series (No Hugging, No Kissing, Never Say "Die", etc.) Although it played up the violence and played down the romance compared to its Distaff Counterpart The Nancy Drew Files. Might qualify as a Quietly Performing Sister Show since it had a successful run of 12 years (1986-1998) and 127 issues.
- The Hardy Boys are: The Clues Brothers and The Hardy Boys Secret Files: Spinoff Babies series which both involve 8 and 9-year-old versions of Frank and Joe solving mysteries in the vein of missing pet cats.
- Hardy Boys: Undercover Brothers: Considered a continuation of the original series by the publisher, it hovers somewhere between the Originals and the Casefiles in terms of storytelling (less graphic than the Casefiles, but also more liberal than the Originals.)
- Both the Casefiles and Undercover Brothers spin-off had their own spin-off, a Crossover series with Nancy Drew. Interestingly, they were both titled Nancy Drew-Hardy Boys Supermysteries. (Fans tag them '88 and '07 for the sake of avoiding confusion.) Both shared a lot of similar traits, including hinting at Nancy/Frank and Bess/Joe relationships.
- Sudden Sequel Death Syndrome: Iola in the first chapter of the first Casefiles book.
- Tap on the Head: Frank & Joe have both been knocked out by getting hit in the head so often that, in real life, the two should be vegetables in permanent coma in the hospital.
- Teen Genius: Frank
- Wham! Episode: the very first Casefiles book, with the death of Iola in the opening chapter.
- Working the Same Case
