* ''Literature/{{Quarters}}'': ''Fifth Quarter'''s plot is sparked when Gyhard, Bannon and Vree's target, does this to the latter. Bannon finds himself in Aralt's dying body, having to [[SharingABody share Vree's]].

* Sir Creator/ArthurConanDoyle's short story "The Great Keinplatz Experiment."

* In ''Literature/TheShapeChanger'', Lafayette O'Leary finds himself swapping bodies with a series of strange people for reasons he doesn't entirely understand. It starts with a local thief named Zorro, but soon after, he finds himself swapping with people from other worlds. It's an unusual variant where the minds stay where they were, and the ''bodies'' change places.

* ''Dragon Princess'' by S. Andrew Swann: Main character Frank is [[StandardHeroReward offered the hand of the princess]] if he can [[DragonsPreferPrincesses rescue her from the dragon]], but it turns out to be a trap by the Royal Wizard who intends to use a Body Swap spell to steal Frank's body and marry the princess himself. Only the spell goes wrong and [[GenderBender Frank ends up in the princess's body]], the dragon ends up in the wizard's body, and the princess ends up in the ''dragon's'' body! After the dust clears [[spoiler: Frank had to kill the wizard (in his old body, so Frank could never return to it) to save the princess (in the dragon's body), while the dragon (in the wizard's body) was forced into servitude for TheFairFolk to cover his enormous gambling debt (which was why he'd kidnapped the princess in the first place). And thanks to the ExactWords of the kingdom's law, the princess (in the dragon's body) is forced to marry Frank (who's in her old body).]]
* ''Literature/FearStreet'' has ''Switched'', where a depressed girl named Nicole is offered to switch bodies with her friend Lucy. [[spoiler: Subverted when it turns out that this was all in her mind, as Lucy died a while ago and Nicole couldn't cope with it]].
** It's sister series, ''Literature/GhostsOfFearStreet'' had ''Body Switchers from Outer Space'', where a klutzy boy named Will switches with the popular kid, who turns out to be an alien.
* In Beatrice Gormley's ''Fifth Grade Magic'' protagonist Gretchen and her rival Amy spent most of a day in each other's bodies as the result of an overly-enthusiastic {{Fairy Godmother}} wannabe.
* Mary Rodgers' 1972 novel ''Literature/FreakyFriday'', on which the film adaptations are based and for which the trope is directly or indirectly named, switched a mother and a daughter.
** The sequel, ''Summer Switch'', swaps the other members of that family, the father Bill and the son Ben (a.k.a. Ape Face).

* Happens to two of the protagonists of Creator/EstherFriesner's ''Harpy High''; since one of them has a physically abusive father, the other one acquires a little more understanding than he wanted.

* Occurs in Paul Collin's ''Jelindel Chronicles''. Zimak tricks Daretor into swapping bodies, after saving him from a prince who was trying to do just the same. Daretor by this point is getting truly frustrated, as already his sword skills were magically stripped from him, and now he had to deal with being in a much weaker body after being a tank. And in these books, changes tend to be permanent.

* In ''The Mirror'', by Marlys Millhiser, the titular family heirloom swaps Brandy [=McCabe=] (in 1900) and granddaughter Shay Garrett (in 1978) on the eve of each woman's wedding.

* Anton and Olga switch minds in ''[[Literature/NightWatchSeries The Night Watch]]'' as part of a plan to draw out a plot by the Day Watch. The scene also averts NoPeriodsPeriod by having Olga tell Anton that he's lucky this isn't happening a few weeks later, or she'd have to instruct him on the use of tampons. In a DeadpanSnarker manner, Anton replies that he knows what needs to be done: he needs to pour some blue liquid on the tampon and the squeeze it in his fist, like all the commercials show. Anton's reply is absent in the English translation (possibly because women use pads now).
** The film version has this swap occurring in the second movie, ''Day Watch''.

* The 1931 novel ''Turnabout'' by Thorne Smith (see above for the 1940 film adaptation), in which suburban couple Sally and Tim Willows have their bodies switched by the statue of a minor deity in their house who becomes fed up with their constant bickering. Sally now has to take over her husband's job in an advertising agency and on a drunken night manages to impregnate Tim, who in chapter XVIII "was delivered of his child and became by virtue of the achievement the first male mother on record."

* OlderThanRadio: Used in F. Anstey's 1882 novel ''Vice Versa'' to swap a father and son. This may have inspired Mary Rodger's 1972 novel.
* In Marghanita Laski's novel ''The Victorian Chaise Longue'', a modern woman buys a Victorian couch at a bargain price because it has an old dried bloodstain that can't be removed. Falling asleep on the couch, she wakens on the same couch in Victorian times, inhabiting the body of the couch's original owner. The couch is now new and unstained, and the woman suspects (correctly) that her impending death will cause the bloodstain.

* This is the focus of Franny Billingsley's ''Well Wished''. Nuria tries to trick her town's JackassGenie of a wishing well into giving her crippled friend Catty the ability to walk, and ends up wishing that "[[ExactWords Catty would have a body just like mine]]." The result is the girls spending the holiday season in each other's bodies. Nuria undoes the switch by [[spoiler:sneaking a new wish into Catty's lines in their play.]]
* In Creator/AlexandreDumas's ''The Wolf Leader'', the protagonist uses his pact with the (magical) wolves to switch bodies with a local baron for 24 hours, in order to sleep with a countess having an affair with the baron. He is discovered and mortally wounded by the countess' husband, but just then, the 24 hours elapse and the protagonist switches back to his own body... [[spoiler:which turns out to be trapped inside a house set on fire by angry villagers fed up with his dark powers]].

* ''Literature/FearStreet'' has ''Switched'', where a depressed girl named Nicole is offered to switch bodies with her friend Lucy. [[spoiler: Subverted when it turns out that this was all in her mind, as Lucy died a while ago and Nicole couldn't cope with it]]. It's sister series, ''Literature/GhostsOfFearStreet'' had ''Body Switchers from Outer Space'', where a klutzy boy named Will switches with the popular kid, who turns out to be an alien.

* In ''Literature/WhyImAfraidOfBees,'' Gary, the main character, stumbles upon a ''service'' that switches you with whoever you want. However, he accidentally ends up in the body of a bee. [[HilarityEnsues Horror ensues]].

* In the ''Literature/{{Goosebumps}}'' book "Why I'm Afraid of Bees", Gary, the main character, stumbles upon a ''service'' that switches you with whoever you want. However, he accidentally ends up in the body of a bee. [[HilarityEnsues Horror ensues]].

* In Creator/DianaWynneJones's book ''Literature/TheOgreDownstairs'', a mystical chemistry set leads (among other things) to two kids in a recently blended family switching bodies for a day. This is the first step towards the two sets of children actually getting along. The swap is discovered after two ''not himself'' situations.

* ''Literature/MagicByTheNumbers''': This happens to the male heroes of ''Riddle of the Seven Realms'', as a side effect of a time/space-warping magical weapon. Unusual in that it's done neither for social commentary ''nor'' comedy; rather, it gives the djinn hero a chance to experience life as a human, and vice versa.

* The basis of Creator/PGWodehouse's novel ''Literature/LaughingGas'', in which Reginald, third Earl of Havershot, and Joey Cooley, child film star and the Idol of American Motherhood swap bodies while under sedation at the dentist. Reggie's narration makes clear that this was already a well-worn trope by the 1930s, as Reggie is familiar with the idea and muses about how in fiction, the people who fall victim to this are never believed.
* OlderThanRadio: Used in F. Anstey's 1882 novel ''Vice Versa'' to swap a father and son. This may have inspired Mary Rodger's 1972 novel.

* ''Literature/MagicByTheNumbers''': This happens to the male heroes of ''Riddle of the Seven Realms'', as a side effect of a time/space-warping magical weapon. Unusual in that it's done neither for social commentary ''nor'' comedy; rather, it gives the djinn hero a chance to experience life as a human, and vice versa.
* Creator/JackChalker uses this trope in so many books, a character in the round-robin novel ''Literature/TheRedTapeWar'' [[BreakingTheFourthWall breaks the fourth wall]] to complain that he's overdone it and ask the other authors why they don't rein him in.
* In the ''Literature/{{Goosebumps}}'' book "Why I'm Afraid of Bees", Gary, the main character, stumbles upon a ''service'' that switches you with whoever you want. However, he accidentally ends up in the body of a bee. [[HilarityEnsues Horror ensues]].

* ''TabletopGame/MagicTheGathering'': In ''Literature/AgentsOfArtifice'', Jace Beleren accidentally induces a flip between [[spoiler:himself and his friend Kallist]]. The swap is so thorough that neither party even realizes anything has changed--each goes about his own business as usual, believing himself to be the other.
* In Beatrice Gormley's ''Fifth Grade Magic'' protagonist Gretchen and her rival Amy spent most of a day in each other's bodies as the result of an overly-enthusiastic {{Fairy Godmother}} wannabe.

In "The Case of the Rich Woman", a rich widow named Abner Rymer comes to Parker Pyne requesting help with her boredom since she has buckets of money and nothing enjoyable to do with it. He hires a doctor who manages to switch her body with an IdenticalStranger farmgirl named Hannah. Things seem to go wrong almost immediately when Abner reads a newspaper suggesting that Hannah was locked in a mental institution for claiming she wasn't Abner. [[spoiler:It turns out to be a subversion. "Hannah" never existed and the newspaper was fake. This was all part of a plan to give Abner happiness. It works.]]
* The premise of the Todd Strasser book ''Literature/HelpImTrapped in My Teacher's Body'', as well as most, but not all, of its sequels.
* Near the end of book six of ''Literature/CaptainUnderpants'', Mr. Krupp and Melvin Sneedly accidentally swap bodies. Getting them to swap back takes up much of the plot of book seven.

* One of several {{Gamebooks}} based on ''VideoGame/ClubPenguin'' (the "Pick Your Path" books), "The Great Puffle Switch", is based around the viewpoint character (a penguin, obviously) swapping bodies with their pet Puffle (i.e. small fuzzy limbless creatures kept as pets on Club Penguin for the uninformed) after a [[LightningCanDoAnything lightning related]] mishap at the Night Club.

* In ''Literature/MyBrotherIsASuperhero,'' Zack and Luke switch bodies in the fourth book, meaning that Luke [[AscendedFanboy finally has a chance to experience having superpowers]].
* In kid's picture book ''A Twisted Tale'' by Carolyn Fisher, the animals that live on a farm belonging to the Tarbell family end up apparently switched around this way after getting sucked up by a tornado, resulting in the cow crowing every morning while the duck moos, the cat barking at and chasing the screeching dog, and the oinking chickens wallowing in mud while the quacking pig wades in the water and wrinkles up like a prune. After numerous failed attempts to return the animals to normal, the farmer's daughter solves the problem by going to the fair and loading up herself and the animals onto a tornado-themed roller coaster. The ride returns the animals to normal, but [[NotQuiteBackToNormal with the side-effect of]] turning the daughter into a wind-swept, noodle-limbed nut.
* ''Literature/FearStreet'' has ''Switched'', where a depressed girl named Nicole is offered to switch bodies with her friend Lucy. [[spoiler: Subverted when it turns out that this was all in her mind, as Lucy died a while ago and Nicole couldn't cope with it]]. It's sister series, ''Literature/GhostsOfFearStreet'' had ''Body Switchers from Outer Space'', where a klutzy boy named Will switches with the popular kid, who turns out to be an alien.
