[[caption-width-right:250: One of the most infamous examples of incestuous ShipMates in the history of literature.]]

When a pair ([[OneTrueThreesome or more]]) of characters who are given the {{Shipping}} treatment are related to each other.

Incest is a serious taboo among human beings--most cultures have an incest taboo[[note]]Now, the sticking point and source of ValuesDissonance is that while all these cultures agree that incest is wrong, most of them have different ideas of what constitutes incest--but further exploration of this topic is better suited to your anthropology textbook[[/note]]. Despite this, [[ForbiddenFruit or perhaps because of it]], there is a significant amount of people interested in it, [[RuleThirtyFour and this being]] [[TheInternetIsForPorn the Internet]], they can't wait to share their {{shipping}} theories with you.

Even with the taboo, they might have an easier job than the HoYay [[{{Shipping}} shippers]], since normal family members are often so close to each other, both physically and emotionally, that with any other partner it can easily be interpreted as romantic and/or sexual. Just pick up any dialogue between relatives, [[SelectiveObliviousness ignore the obvious intentions]], and Ta-da! you have subtext. There's also a good chance that you have [[NoYay disgusted, repelled, or otherwise alienated the entire rest of the fandom]]--but if the fandom is big enough, there's a chance you'll find like-minded company anyway.

This is a subpage for fandom theories. When the same effect is featured in the work in question that is actual IncestSubtext. See also HoYayShipping and FoeYayShipping for other shipping tropes that are based on fan-speculation, and IncestIsRelative page for a collection of other incest-related tropes.



[[folder:Anime & Manga]]
* The anime for ''Manga/DotHackLegendOfTheTwilight'' was notorious for this to the point that it's what a lot of non-fans of the series in general tend to know it for. The manga it was based on, on the other hand, was vague about it at best.
* ''Manga/AngelSanctuary'' could not be more blatant about Setsuna and Sara, but some see this between Rociel and Alexiel as well.
* ''Manga/AxisPowersHetalia'':
** The very ship-happy fandom naturally has much of this. Switzerland and Liechtenstein, Russia and Belarus (though that one's canon [[{{Yandere}} on Belarus' side]]), China and Korea, etc.
** [[IdiosyncraticShipNaming Germancest]] (Germany/Prussia) is a really popular pair, even more popular than canon or plausible couples like Prussia/Hungary, Austria/Hungary or Finland/Sweden. Prussia's behavior around Germany is borderline on flirting, but this is quite normal anyway, because it's ''[[MemeticMolester Prussia]]''.
** The NotBloodSiblings cases, like England and America, or China and Japan. Though England and America look so much alike it seems to some of the fandom like a case of ScrewYourself.
** Norway and Iceland shipping ''increased'' somewhat after the revelation of their relation came out because it attracted shippers who liked the "forbidden" appeal.
** Many fanfics featuring England's brothers (namely Scotland, Ireland, Wales and sometimes Northern Ireland) really love to play up the sibling rivalry setup for all the FoeYay it is worth.
** Veneziano Italy and Romano Italy are, in fact, half-brothers, similar to the situation with Norway and Iceland. Naturally, following along the Germancest lines (or perhaps predating it), together they're called Itacest.
* Ichigo / [[spoiler:Uryuu]] is a relatively common ''Manga/{{Bleach}}'' {{Yaoi}} pairing. Later chapters of the manga revealed that [[spoiler:Uryuu's father and Ichigo's mother were first cousins, making the boys second cousins]], so this is also a case of SurpriseIncest. The revelations have not much dampened enthusiasm for the ship. [[spoiler:Ryuuken and Masaki had a failed ArrangedMarriage in canon, so clearly the cousin thing isn't an insurmountable barrier. While very much a minority pairing as it contradicts canon 'ships, there's also some fandom for Ryuuken/Masaki as well.]]
* ''Anime/CodeGeass''. It's just all over the place in that show, it even has its own BrotherSisterIncest page.
* ''Manga/DGrayMan'' has Komui and Lenalee Lee. Komui's rather intense sister complex does nothing to disprove this.
* From ''Anime/DragonBallZ'' there are some people who ship opposite-sex twins Androids 17 and 18 together. Also, there's the pairings of "Son-cest" (various incestuous pairings within Goku's family) and Vegeta/Trunks or Vegeta/Future Trunks. There's not a lot of it but Vegeta/Bra exists too.
* Agon and Unsui of ''{{Eyeshield 21}}'' is THE incest pairing of the fandom. It's not all that hard to see why, Agon is (without a doubt) the most important person in Unsui's life and Agon's a sociopathic playboy and {{memetic molester}} whose feelings for his brother are left ambiguous.
* ''Manga/FullmetalAlchemist'':
** Brothers Edward and Alphonse are one of the most popular shipping targets in the fandom, with the [[Anime/FullmetalAlchemist 2003 anime]] infamous for showing how close the brothers really are. Acommon saying amongst fans of the relationship is that 'they broke so many taboos already, what's one more?'
** A case of SurpriseIncest happened in the 2003 anime. Edward and [[spoiler:Envy]] are a popular pair due to the FoeYay between them however near the tail end of the series there's a twist: [[spoiler:Envy is Ed's half-brother]]. Instead of abandoning ship a lot of fans only saw this as making the pairing more interesting.
* [[BrotherSisterIncest The Nishizumi sisters]], [[TheHero Miho]] and [[ByronicHero Maho]] from ''Anime/GirlsUndPanzer'' are a surprisingly popular pairing among the fandom, since there are no male characters who are the girls' ages, and relatively little LesYay. This is only reinforced by the revelation in ''Little Army'' that Maho [[spoiler:in contrast to her initial impression as an AloofBigSister, loves Miho enough to live up to being Nishizumi heiress so that Miho will not have to]].
* ''Anime/KillLaKill'' has [[spoiler:Ryuko/Satsuki]]. They were already a pretty popular ship because of the FoeYay, but then they were revealed to [[spoiler:be sisters]] and then it skyrocketed. To add even more fuel to the fire, the ending has the two [[spoiler:[[ItMakesSenseInContext embracing while naked.]]]]
* ''Manga/{{Naruto}}'':
** The number of Itachi/Sasuke fans would surprise newbies, and the size of the fandom only seemed to ''increase'' when [[spoiler:Itachi died and Sasuke learned that Itachi had done everything--including killing the rest of his family--for Sasuke's sake]].
** [[KissingCousins NejiHina]] is the second most popular incest pairing, though it bears mention that Japan has less of a taboo regarding relationships between cousins than Western nations do.
** Naruto and [[spoiler:Kushina]] boomed in popularity due to the blushing and compliments, along with [[spoiler:Kushina]] being comparable to [[spoiler:Naruto's crush, Sakura]].
* The brothers Ace and Luffy are a fairly popular pairing in the ''Manga/OnePiece'' fandom. And since the flashbacks to their childhood there is also now [[spoiler:Sabo]]/Luffy, Ace/[[spoiler:Sabo]], and [[spoiler:Sabo]]/Luffy/Ace {{OT3}} shipping. In a looser definition, Ace is also often shipped with his crew mate Marco, who is as much of a brother to him as Luffy is.
* ''LightNovel/{{Oreimo}}'' is built on this, with a fanbase largely formed of people who want to see Kousuke and Kirino together. [[spoiler:They do in the end.]]
* Hikaru and Kaoru Hitatchiin from ''Manga/OuranHighSchoolHostClub'' make this easy, deliberately playing up the {{Twincest}} angle for the benefit of their fans. Their actual relationship is left ambiguous, but real life fans love it as much as the fictional ones.
* ''PandoraHearts'': Gil's younger brother, Vincent, is [[{{Yandere}} extremely possessive]] of him.
* ''Anime/PantyAndStockingWithGarterbelt'' has plenty of fans that ship the title sisters together. Their evil counterparts, Scanty and Kneesocks, also have this going, though in their case it's also canon.
* In ''Manga/PeacemakerKurogane'', Tatsunosuke's overprotectiveness over his younger brother Tetsunosuke sometimes causes this.
* ''{{Manga/Saki}}'' and Teru Miyanaga sometimes get paired despite canonically not being on good terms, as Teru is unwilling to speak with Saki. Some shippers take Teru's [[IHaveNoSon denying having a sister]] to mean that Teru is ''in love with'' Saki.
* ''Anime/SgtFrog'' has Giroro and his elder brother Garuru which is the most popular Giroro-oriented ship aside from Gironatsu and Girokuru for the Japanese fandom especially. This is most likely due to the lengths Garuru goes to ensure Giroro remains on his mission as well as Giroro's admiration for him/frantic, embarrassed reactions when he's near. The Hinata family is shipped together sometimes as well.
* ''Anime/TengenToppaGurrenLagann'' fandom has not insignificant sect of Simon/Kamina shippers, who call each other their brother.
* In ''Manga/{{Touch}}'', Yuka Nitta is, at least at first, very protective of her older brother and a bit too concerned at the prospect of him having a love life.
* In ''Manga/ToLoveRu'' many fans love pairing Mikan and Rito. Even Momo In-Universe would include Mikan in The Harem Plan.
* ''Manga/VampireKnight'' had Zero and Ichiru. And the [[spoiler:Kuran]] family has a history of incest, as seen in the current generation between [[spoiler:Kaname and Yuuki.]] Many people do ship them.

[[folder:Comic Books]]
* Leonardo and Raphael of ''Franchise/TeenageMutantNinjaTurtles'' fight in such a way half the time that it comes off more like BelligerentSexualTension than actual SiblingRivalry. This is especially noticeable in the recent 2007 film.
* Wanda and Pietro Maximoff, aka ScarletWitch and {{Quicksilver}} from the ''Comicbook/{{The Avengers}}'', were seen in this light, especially Pietro and his overprotective instincts. In the alternate universe title ''TheUltimates'', [[BrotherSisterIncest however...]]
* ''ComicBook/PowerPack'', being a sibling team, gets this a lot. In the all-ages version, Jack and Katie get this from some fans due to their constant bickering. [[http://asylums.insanejournal.com/scans_daily/21731.html A sweet moment between their future selves]] doesn't help due to the [[DoesThisRemindYouOfAnything way]] [[RelationshipWritingFumble it's drawn]].
* ComicBook/{{Daken}}'s private thoughts about little "sister", ComicBook/{{X 23}}, upon seeing her in action once their various conflicts, double-crossings, and manipulations are put aside so they can focus on dealing with Colcord are out of the way, can easily be read with a romantic subtext. And considering this ''is'' [[AnythingThatMoves Daken]] we're talking about...it certainly puts fuel into the fire among some of the fans and makes Daken one of Laura's [[LauncherOfAThousandShips many fandom pairings]].

* ''Disney/{{Frozen}}'' fans love shipping the sisters Elsa and Anna. Even though she has a male love interest, Anna spends the entire movie wanting to see Elsa, wanting to spend time with Elsa, worrying about Elsa more than anyone else, and risking her life to save Elsa, fulfilling the "prince rescuing the princess" role. For her part, Elsa's fear of showing off her ice powers to anyone and hurting her sister has an [[DoesThisRemindYouOfAnything "in the closet" subtext thing]] going on. And in the end, the movie subverts the trope of [[spoiler:TrueLovesKiss by having the love that saves Anna be her sisterly love of Elsa]].
* ''Disney/MeetTheRobinsons'' has some fans who ship Wilbur and [[spoiler:Lewis, his father]]. The 'ship is aptly referred to as "Timecest".
* ''Disney/BigHero6'' is getting a lot of Tadashi/Hiro slash.
* Arrow and Rudolph is a pretty popular pairing for fans of ''WesternAnimation/RudolphTheRedNosedReindeer The Movie'' due to their rivalry making for good FoeYay. Most fans do not notice they're cousins.

* In ''Film/RepoTheGeneticOpera'', Luigi and Amber. Particularly the bit where she knees him in the groin and licks his ear at the same time. According to their brother Pavi's myspace page, ''he'' and Amber are also rather unhealthily close. And a surprising number of fans [[FoeYay ship Luigi and Pavi]] (or [[PortmanteauCoupleName "Pavigi"]]).
* In a director's-cut scene from ''Film/TheLordOfTheRings: The Two Towers'', a lot of what we'll call Stewardcest fangirls point for evidence to this moment that's very subtle, but oddly difficult-to-explain-otherwise when you notice it: Denethor dismissively comments about his younger son, Faramir, "I know his uses. They are few." Now think about the implications of the word "use." And rewind and look at Boromir's expression again: It's not "oh, dad, you're so mean", it's ''embarrassed''.
* The ''Franchise/{{Halloween}}'' fandom really likes the Michael/Laurie pairing even though he wants to kill her.
* Film/{{Thor}} and Loki may be the most popular ship in the Franchise/MarvelCinematicUniverse, which is saying a lot.
* The most popular pairing in the fandom for ''Film/HanselAndGretelWitchHunters'' by far is Hansel/Gretel.
* In ''Film/PacificRim'', two (or in one case three) member teams pilot giant robots using the techno-telepathic Drift. Between the very intimate memory sharing and emotional connections, special "drift compatibility" needed between pilots (and the one successful Drift compatibility trial seen on screen being described as akin to a sex scene by the director) and the fact that a pretty large number of teams seem to be related, incest is a pretty common in the PR fandom. The most prominent example is the lone parent/child team of Herc and Chuck Hansen, which also happen to be one of the most shipped pairings in the fandom. Probably helped that other characters comment on Chuck's "daddy issues", that supplemental material and WordOfGod states that Herc never remarried after Chuck's mum died and that Chuck never dated at all, and that the age gap between their actors is only a bit more than a decade.
* Not only did a lot of ''Franchise/StarWars'' fans ship Luke and Leia back in the day, but so did a lot of merchandise, advertising and spin-off material (most infamously ''Literature/SplinterOfTheMindsEye'', published before ''Film/TheEmpireStrikesBack''). Nowadays, you have to look to find it, but it's still around.

* ''Literature/HarryPotter'':
** Many fans think that Bellatrix and Narcissa fit the bill for this and write extensive fanfics about it. WordOfGod confirmed that Bellatrix loves Voldemort above all else; some fanfics manage to get around this fact.
** Fred and George have a veritable library of slash work dedicated to them, even though [[http://i29.tinypic.com/zwib29.jpg their actors are disgusted by it all]].
** Ron/Ginny. Ron is quite annoyed by the fact that Ginny dates Dean and he silently interferes between her and Harry at first, but he relents later and becomes more accepting of their relationship.
* ''Literature/TheChroniclesOfNarnia'':
** Sibling protagonists [[ShipMates Peter/Susan and Edmund/Lucy]] get a considerable amount of [[FanFiction fanfics]]. One of the reasons may be that the first book (and movie) implies they're the only humans that live there, without mentioning the fact that there are other lands around Narnia in which reside other people. (Although the first book ''does'' state that the kings of countries beyond the sea have sent ambassadors asking for Susan's hand in marriage. No word on whether or not they were human.)
** Peter and Susan get some, although it's mostly [[Film/TheChroniclesOfNarnia the movie versions]], due to the actors' chemistry and close friendship that has been interpreted in the wrong way. And there's a whole lot of Peter/Edmund, too.
* ''Literature/TheLordOfTheRings'':
** Merry and Pippin are first cousins and are often shipped together by fans. Sometimes Frodo, more distantly related to both of them, is thrown into the mix as well. See ''FanFic/BagEnders'''s "Random Slashy Interludes" for a prime example.
** Perhaps one of the most popular pairing in ''Literature/TheSilmarillion'' is Maedhros/Fingon; these two share a grandfather, Finwë. As do Celegorm and Aredhel, also paired rather often. And then the house of Finwë as a whole is very popular and more generally EveryoneIsRelated.
** Most fanfic treats the canon [[BrotherSisterIncest Túrin/Niënor]] pairing as tragic, like the book in which they're the title characters--but there's fanfic.
** As soon as the first ''Film/TheHobbit'' movie came out, there was an explosion of Fíli/Kíli slashfic. Many (but not all) of them operate from the canonical statement that dwarves love only once, and assume that the brothers have bonded to each other. Reactions of those around them vary from complete acceptance to revulsion.
* ''Literature/WarriorCats'':
** Hawkfrost/Brambleclaw, which has its own [[IdiosyncraticShipNaming ship name]]: Brothershipping. They're half-brothers, which is probably the only reason it isn't banned from discussion on Website/WarriorsWish.
** The reveal that [[spoiler:Firestar and Scourge]] are half-brothers means [[spoiler:Altershipping]] also falls under this trope.
* ''Literature/PercyJacksonAndTheOlympians'':
** Percy and Annabeth. Despite being closely related via their respective parents, Poseidon and Athena, [[spoiler:they like each other romantically and get together by the end of the series]].
** Some fans pair Percy and/or Annabeth with their demigod [[KissingCousins cousins]], including Thalia (Zeus's daughter) with Percy and Annabeth with Luke (Hermes's son). Annabeth also has a crush on Luke early in the series.
** Since shipping any demigods together is both incest and not[[note]]gods don't have DNA, so the only people in camp who are off-limits incest-wise are those with whom you share a godly parent, but all the gods are related somehow, so all campers are part of the same family[[/note]], technically any ship between campers both falls under this trope and doesn't.
* ''Literature/ASeriesOfUnfortunateEvents'' had a small Violet/Klaus fandom that got quite a bit larger after the release of the movie adaptation.
* A strict NoHuggingNoKissing policy during the original run of ''Literature/TheHardyBoys'' (alongside the stressful adventures giving the boys a very powerful brotherly bond) led a lot of people to acknowledge that Frank and Joe seemed very indifferent to their respective girlfriends Callie and Iola and way more interested in each other.
* Despite them being mortal enemies and having strong canon pairings with people of no blood-relation to them, Sam and Caine have been shipped together in the ''Literature/{{GONE}}'' fandom, and it's actually pretty popular. The ship is known as "Saine"...or "{{twincest}}".
* ''Literature/TheDresdenFiles'' fanbase commonly ships Harry with his half-brother, Thomas (usually ignoring the fact that both of them have serious female love interests). This is probably because Thomas is an [[CharmPerson incubus]], who naturally arouse sexual feelings in those around them, and because it was several books before said relation was revealed. The fact that Thomas masquerades as a gay hair dresser and they were MistakenForGay as a couple at least once in series (which they would later use to their benefit) doesn't help matters.

[[folder:Live-Action TV]]
* This is referred to by the ''Series/{{Firefly}}'' fandom as "CSI" or "Crazy Space Incest", seeing this between River and Simon Tam. Creator/SummerGlau's [[http://www.youtube.com/watch?v=9JCvpFG-Ll4 opinion on the matter at 0:35]]. Creator/SeanMaher seemed to approve, though.
* Justin and Alex in ''Series/WizardsOfWaverlyPlace'', to the point where the pairing used to have a separate Incest Yay page until it was sent [[http://fetishfuel.wikia.com/wiki/Incest_Yay%3AWizards_of_Waverly_Place here]].
* Quite common in ''Franchise/KamenRider'' series. Especially ''Series/KamenRiderKiva'' and its many bathing scenes. However, "Kivacest" typically refers not to Wataru and Otoya, despite their ''epic'' TimeTravel-enabled bath scene (with back scrubbing!), but to Wataru and [[spoiler:Taiga]], who turns out to be his brother.
* ''Series/{{Supernatural}}'':
** The Wincest shippers see this between brothers Sam and Dean Winchester. During the early seasons, it was unquestionably ''the'' [[FanPreferredCouple most popular pairing]] in the fandom[[note]]for the first few seasons, slash-ship options were pretty much limited to incest or RPF, and het-shipping would require characters who were either dead, not mentioned beyond one episode, or generally reviled by the fanbase. The ridiculous chemistry the two main actors have only contributed[[/note]]. It's died down some since Castiel showed up[[note]]the current FanPreferredCouple is Dean/Castiel, but Sam/Castiel and Dean/Sam/Castiel have their fans as well[[/note]], but the Wincest fanbase is still significant.
** Since all of the angels are canonically siblings, shipping any of them together falls under this. It's sometimes called "angelcest" or "wingcest" within the fandom. The most popular of these pairings is probably [[ArchangelMichael Michael]]/[[{{Satan}} Lucifer]].
* ''Series/{{Heroes}}'':
** Maya and Alejandro Herrera are twins who seem to be a little too close to each other; even their powers require physical connection. You didn't need to ask the fans twice.
** Peter and Nathan Petrelli are brothers who are extremely close, despite an age difference of at least 13 years. There is a reason they're the most popular slash pairing in the show. Not helping is how friendly Adrian Pasdar and Milo Ventimiglia are in real life.
** Peter and Claire seem to be closer than one would expect of uncle and niece, and their shipping fandom only slowed down slightly after that little revelation. Then there's [[CastIncest Milo and Hayden's off-screen relationship]].
* ''Series/{{Dexter}}'':
** Dex naturally gets much shipping with [[spoiler:his brother Rudy/Brian]], what with all the [[DoesThisRemindYouOfAnything sexual symbolism]] the show blends with his murdering.
** The show runners tried to keep the [[CastIncest Michael C. Hall and Jennifer Carpenter marriage]] quiet for a while specifically to avoid this trope. It didn't work. They clearly changed their minds, though--as of Season 6, Deb lusting after her brother is canon.
* ''Series/{{Chuck}}'' was [[WhatCouldHaveBeen originally intended]] to have an extra character in the main cast, a love interest for the titular hero. After it was decided she overcomplicated things, she was cut, and all her important lines given to Chuck's sister. The slightly flirty dialogue, coupled with the siblings' chemistry, made this stand out to more than one fan.
* When ''HomeAndAway'' revealed that sisters Charlie and Ruby Buckton were actually mother and daughter, one website brilliantly proclaimed that it made shipping them feel even more wrong. They even seem to have acquired their own couple portmanteau, even if it is mostly used in a familial context.
* ''Series/{{Revolution}}'' has a small, but devoted sector of Charlie/Miles shippers. They are niece and uncle, and possibly father and daughter considering Miles affair with Rachel, but share a lot of tropes usually reserved for romantic interests. A RelationshipWritingFumble may have also happened since they have a lot of BelligerentSexualTension that turns into UST later. They also have their fair share of heartwarming moments.
* ''Series/{{Glee}}'':
** Hummelcest between Burt and Kurt Hummel, a rare example of a father/son incest. Considering that they cannot have a scene without declaring their love for each other, it shouldn't be a surprise.
** After Blaine got brother who is [[MrFanservice even more handsome]] than he is, we have Andercest. Not at all helped (or immensely helped, for those who like this sort of thing) by the line "We're not just brothers, right?" said while standing with their [[AlmostKiss faces mere inches apart]].
* ''Series/{{Angel}}'': There ''are'' fans who have written Darla/Connor and Angelus/Connor stories.
* ''Series/TheBorgias'': [[ParentalIncest Rodrigo]]/[[DaddysGirl Lucrezia]] and [[SiblingRivalry Cesare]]/[[FoeYay Juan]] shippers exist in abundance.
* The ''Series/{{Frasier}}'' fandom has some Frasier/Niles shipping, otherwise known as "Cranecest".
* The ''Series/LifeWithDerek'' fandom give us [[NotBloodSiblings Derek and Casey]] aka [[PortmanteauCoupleName Dasey]].
* There's a huge and passionate faction of Klaus/Rebekah shippers in ''Series/TheVampireDiaries'' and later ''Series/TheOriginals'' fandoms. Joseph Morgan and Claire Holt's chemistry and dialogs straight out of dark romance novel? Check. Eye sex and tension? Check. Jealousy, obsessiveness, highs and lows? Check. Makes Klebekah the royal couple of the show and one of the most popular ships.
* ''Series/TheWaltons'', a much-loved Depression-era drama from the 1970s, contains several examples, mostly because it features seven siblings of similar ages. John-Boy and Mary Ellen, the eldest siblings, were infamous in the early seasons for being [[IncestSubtext a little too close]]. John-Boy tells Mary Ellen that her breasts will grow, gives her flowers because he wanted to be her 'first', and frequently dances with and consoles her. Basically, there's plenty of [[UnresolvedSexualTension sexual tension]] to go around. Jason and Erin, younger siblings, also seemed very fond of each other, though this was most likely because of actor chemistry.
* ''Series/{{Arrow}}'':
** Right from the pilot, fans already commented that Oliver has more chemistry with his sister that with his ex-girlfriend. Doesn't help that by giving her the nickname "Speedy" the writers seem to have destined her to be his sidekick, and that despite a slight name change the character is clearly based on comics character Mia Dearden (their first names sound similar, she was shown having a trophy for archery in her room in the pilot, and her middle name was eventually revealed to be "Dearden") whom comics Oliver has shown romantic interest towards in the past. And then after Thea came back from Corto Maltese she asked him to move in with her.
** In hindsight, turns out anyone who shipped [[spoiler:Tommy/Thea]] inadvertently fell into this trope.
* ''Series/{{Skins}}'' has a lot of subtext between [[BrotherSisterIncest Tony and Effy Stonem]] and between [[{{Twincest}} Emily and Katie Fitch]] (or, at least, one-sided from Katie to Emily). In the case of the former, it's made "Stonemcest" a surprisingly popular ship in the fandom.
* Deliberately invoked in-story by Richard III in the BBC/Starz series ''The White Queen'', as per his explanation to his wife Queen Anne that he is not actually having an affair with his niece Elizabeth, but that he just wants everyone to think he is, since she is betrothed to his political rival Henry Tudor, and that [[DeliberateValuesDissonance by cuckolding Henry, he will cost him political support]]. Turns out he actually is having an affair with his niece, and his explanation was rather a lie.
* More than a few people have mistaken Zelda and Hilda from ''Series/SabrinaTheTeenageWitch'' for a couple. The issue comes mostly from mistaking Sabrina calling them "aunts" as referring to one of them being her bio-aunt and the other her lover.

* ''Theatre/{{Hamlet}}'''s [[OedipusComplex subtext with his mom]] inspired a whole ''profession'' of this trope. Doesn't help that [[AgeLift he]] is often older than [[PlayingGertrude her]].
* ''Theatre/RichardII'' (particularly as presented in ''Series/TheHollowCrown'' and/or the RSC version starring Creator/DavidTennant) has [[FoeYay Richard/Bolingbroke]], as well as [[UnequalPairing Richard/Aumerle]] (who share a [[KissingCousins lengthy kiss]] in the RSC version), all cousins. (Specific to the Hollow Crown version of ''Theatre/HenryIVPart1'', the sight of Creator/JeremyIrons slapping Creator/TomHiddleston caused a few [[ParentalIncest fandom ripples]].

[[folder:Video Games]]
* Alfred and Alexia Ashford in ''VideoGame/ResidentEvilCodeVeronica''.
* ''Franchise/FireEmblem'':
** The king and queen of this trope would be [[VideoGame/FireEmblemJugdral Eltoshan and Lachesis]], while the prince and princess would be [[VideoGame/FireEmblemTheSacredStones Eirika and Ephraim]].
** The romance system in ''[[VideoGame/FireEmblemJugdral Genealogy of the Holy War]]'' allows for KissingCousins, of which two pairings are actually half-sibling incest[[note]]Because Aideen and Briggid are identical twins, any children they have are genetic half-siblings. This does not preclude the pairings of Lana/Faval and Lester/Patty[[/note]].
** The romance system in ''VideoGame/FireEmblemAwakening'' allows for cousin marriages as well, although the NA/PAL releases {{Bowdlerize}}d this slightly by referring to such pairings as "[[PlatonicLifePartners companions]]" rather than husband and wife. However, they failed to do this for the ''aunt/nephew or uncle/niece'' pairings that are possible by pairing Chrom with either Maribelle or Olivia and then pairing one of the resulting children with the Avatar and the other with Morgan.
* Fraternal twins Anna and Mihael in ''VideoGame/DragonValor''.
* ''Franchise/FinalFantasy'':
** Faris/Lenna from ''VideoGame/FinalFantasyV'' has some popularity. The general interpretation for this pairing is that Faris' BigBrotherInstinct[[note]]technically ''sister'', but this is Faris[[/note]] towards Lenna is actually romantic interest.
** From ''[[VideoGame/FinalFantasyX2 FFX-2]]'' we have [[KissingCousins Yuna and Rikku]].
** Due to the nature of "[[{{Subtext}} Subtle Romance]]" of ''VideoGame/FinalFantasyXII'', some fans decided to assume that Basch has no eyes for anyone but his twin brother Noah/Gabranth and vice versa.
** And in ''VideoGame/FinalFantasyXIII'', there is Lightning and Serah.
* ''Franchise/MetalGear'': Solid Snake and Liquid Snake. It only gets worse once Liquid possesses Ocelot, who had a big gay crush on their father.
* ''VideoGame/GoldenSun'':
** The most obvious is Felix and Jenna, who are siblings (and appropriately dubbed "[[SurpriseIncest Oopsie-shipping]]" by the fans). Then ''The Lost Age'' introduces Karst, who is absolutely ''obsessed'', easily to a [[ClingyJealousGirl Clingy Jealous]] {{Yandere}} degree, with her (late, by that point) older sister Menardi. Fans also like to pair up [[FoeYay Alex and Mia]], who were confirmed to be cousins by ''Dark Dawn''.
** A 4koma doujinshi, ''Golden Sun Gag Battle'', has Ivan [[PowerPerversionPotential trying out his new Reveal power]] on [[spoiler: Hama and Feizhi's clothes.]] To be fair, ''Gag Battle'' was published before ''The Lost Age'' outed [[spoiler:Hama as Ivan's sister]], making this a rather meta case of SurpriseIncest.
** ''VideoGame/GoldenSunDarkDawn'' brought several new sets of relatives to the table, with the (in)appropriate reaction from the {{Shipping}} fans. Nowell and Rief are treated as a joke couple in most cases, but shipping either of them with [[spoiler:Amiti]] is fair game...and, technically speaking, a distant enough relationship to be legal even by American standards.
* In the ''VideoGame/{{Touhou}}'' fandom every pair (or trio, in the case of the Prismrivers) of sisters is paired with each other to some degree. The Scarlet sisters are by far the most popular target, with the Komeiji sisters being second and working down from there, though shipping the Aki sisters with each other may simply be because they have such a small fandom shipping them with anyone else is rare.
* Hawke/Bethany has a surprisingly strong following in ''VideoGame/DragonAgeII.'' Isabela and Merrill weren't everyone's cup of tea, and Aveline wasn't a love interest. Cue a large amount of people shipping Hawke with his/her younger sister. There's also a considerably smaller, but still noticeable amount of shipping for Carver/Hawke.
* In ''VideoGame/TalesOfSymphonia'', [[spoiler:Kratos and Lloyd]] seemed awful subtexty to a lot of people. Some of them didn't [[AbandonShipping Abandon Ship]] after [[spoiler:it was revealed that [[LukeIAmYourFather Kratos is actually Lloyd's real father]]]].
* Toad and Toadette of ''Franchise/SuperMarioBros'', but it's possible that the fandom doesn't know they're brother and sister and Nintendo [[FlipFlopOfGod can't make up their minds]] about whether they're siblings, friends, or what.
* This was bound to happen with Mario and Luigi themselves since they're the main characters and considering that they live together, do practically everything together and share a pretty strong brotherly love from the fact they have a tendency to [[ManHug hug each other]] in the ''VideoGame/MarioAndLuigi'' games and Luigi, in particular, is more obvious in his admiration for Mario.
* Likewise, [[ThemeNaming Rock and Roll]] (or VideoGame/MegaMan and Roll in the West), whose actual connection varies in their [[VideoGame/MegaManLegends various]] [[VideoGame/MegaManBattleNetwork incarnations]]. The same applies to [[HoYay Rock and Blues]] ([[MarketBasedTitle Mega Man and Proto Man]] in the west).
* ''VideoGame/BioShockInfinite'':
** It's near impossible to find a Lutece fan who doesn't ship them together. In fairness they're not really siblings, but [[spoiler:ScrewYourself]] isn't much better.
** [[spoiler:Booker and Elizabeth]] have an enormous fandom despite the whole [[spoiler:father and daughter]] thing that was kind of an important revelation.
* Considering that they're half-sisters, there's a surprisingly large amount of ''VideoGame/DeadOrAlive'' porn that features Kasumi/Ayane.
* ''VideoGame/{{Blazblue}}'':
** Brothers Ragna the Bloodedge and Jin Kisaragi are possibly the most popular yaoi pairing, and doubly supported by the [[FoeYay two's fierce rivalry.]] What really sells it is Jin's rather unhealthy obsession with killing Ragna, and the creators seem to love to play with it in the various Gag Reels.
** Ragna and Noel Vermillion, whose fandom weren't impeded at all by the revelation [[spoiler:Noel is a clone of Ragna and Jin's sister Saya]].
** Ragna/Nu ([[spoiler:who is also a clone, like Noel]]). Nu is a full blown {{Yandere}} for Ragna, and all of her interactions with him have very [[InterplayOfSexAndViolence overt overtones.]]
* In ''VideoGame/DevilSurvivor'', the second most popular pairing for the protagonist his cousin Naoya. Most of this comes from Naoya's strange obsession with him, but, interestingly, the revelation that [[spoiler:Naoya and the protagonist are also brothers, and in fact the reincarnations of the original Cain and Abel, respectively]] only seems to have made the pairing ''more appealing'' to the fangirls.

[[folder:Visual Novels]]
* ''VisualNovel/AceAttorney'' caters to this trope, but, when you think about it, it's not that surprising: there's shippers for Mia×Maya, Lana×Ema, Jake×Neil, Edgeworth×Franziska, and even [[spoiler:Apollo×Trucy]], all of which have a fair bit of subtext to them. The two incestuous pairings that are by far the most popular in the fandom are [[spoiler:Dahlia/Iris]], from ''Trials and Tribulations'' and Kristoph/Klavier, from ''VisualNovel/{{Apollo Justice|Ace Attorney}}''.
** To be fair, many fans shipped [[spoiler:Apollo and Trucy]] before they knew they were siblings, and [[SurpriseIncest they themselves never found this out]].
* In the visual novel ''VisualNovel/{{Morenatsu}}'', it's not uncommon for fans to ship [[BigFun Tatsuki]] with his father [[PervertDad Tappei]].

[[folder:Web Comics]]
* Since Creator/JayNaylor's webcomic ''Webcomic/BetterDays'' contained actual {{Twincest}}, readers have been joking about something similar happening on its sequel ''Webcomic/OriginalLife'' ever since it got started. And early in the series there were definite undertones of [[BelligerentSexualTension BST]] between Janie and a [[KissingCousins cousin]].
* ''Webcomic/{{Homestuck}}'':
** John/Jade and Dave/Rose--confirmed ecto-siblings with a rather large shipping base. More on the latter, though.
** The amount of Bro/Dave shipping is unsettling when you find out that [[spoiler:Bro is not only Dave's brother, but he was also Dave's ecto-father]]. According to Google Trends, "Stridercest" (Dave/Bro, or sometimes Dave/[[spoiler:Dirk]]) got ''much'' more popular after Act 6 began, which was when [[spoiler:the post-Scratch versions of the Guardians were introduced]].

[[folder:Web Original]]
* Lenny and Elizabeth Priestly of ''Roleplay/SurvivalOfTheFittest'' v3 are seen by most handlers as having an...[[{{Twincest}} interesting relationship]], due to Lenny's protectiveness of her. Some handlers also ship Reiko and Reika Ishida (twins), and Rosa, Frankie, and Ilario Fiametta (triplets).
* In ''Blog/CinnamonBunzuh,'' an ''Literature/{{Animorphs}}'' ReviewBlog, reviewer Ifi ships Ax and Tobias (who are uncle and nephew) [[ScrewYourself while the latter is morphed into the former]].
* In a [[http://agrissas.tumblr.com/post/69590441030/the-rwby-s1-fandom-survey-results poll]] of 817 ''WebAnimation/{{RWBY}}'' fans, 23 said their {{OTP}} was Ruby/Yang, who are sisters.

[[folder:Western Animation]]
* ''WesternAnimation/AvatarTheLastAirbender'':
** The Azula/Zuko shipper fandom was always significant, but the creators surely aren't making it too difficult with [[http://www.youtube.com/watch?v=k-eWsMMJwZ4 such scenes]] (appropriate music added). They have even (jokingly?) shipped Zuko's alter ego with Azula at a convention. On the flip side, Azula acts that way toward [[TheVamp just about everyone]].
** A lot of people give Zuko an [[ParentalIncest Oedipus Complex]], especially after ''[[ComicBook/AvatarTheLastAirbenderTheSearch The Search]]'', often with the idea that their familial affection doesn't overpower any sexual attraction due to years of separation.
* ''WesternAnimation/TheLegendOfKorra'':
** There's a Mako/Bolin fandom. Korra is ''usually'' in the [[{{OT3}} tangle]], but not always.
** [[spoiler:Tarrlok and Amon/Noatak]] became very popular after the season 1 finale, thanks to the buckets and buckets of angst. Who cares if [[spoiler:they both died]]? That's what {{Fix Fic}}s are for.
** Desna and Eska are a pair of CreepyTwins, so this comes into play naturally (again, Bolin is usually in the tangle, but not always). There's even an in-series joke about how ThereIsOnlyOneBed in their hotel suite, though Desna apparently sleeps in the bathtub.
* Lemongrab and his clone, Lemongrab 2, from ''WesternAnimation/AdventureTime'' are one of the most popular ships in the fandom, even after the two actually referred to each other as "brother" in the episode "Another Five Short Graybles". Alternatively, some shippers see this simply as clones and relationship companions, but not necessarily siblings.
* Yin and Yang from ''WesternAnimation/YinYangYo'' have a lot of this going on, especially since they're, you know, [[OppositesAttract opposites]].
* ''WesternAnimation/PhineasAndFerb'':
** In the early days, the title characters seemed to be the most popular ship, though that's ''mostly'' died down. Pairing one of them with their older sister Candace (biological for Phineas) is rarer but still done. [[http://www.youtube.com/watch?v=U872E53BnOk "Gitchee Gitchee Goo means 'I love you'"]]. Riiiiiiiiiiight...
** Suzy's attitude towards her brother is absolutely creepy even for fans of this trope.
* Occurs in some segments of the ''WesternAnimation/{{Animaniacs}}'' fandom, though probably more because there aren't very many other shipping options.
* In ''WesternAnimation/{{Rugrats}}'' and ''WesternAnimation/AllGrownUp'', some people ship Chuckie and Kimi together. On the other hand, Phil and Lil probably have more shippers and they're {{twin|cest}}s.
* Papa Smurf and Smurfette in ''WesternAnimation/TheSmurfs'', while not biologically related, get constantly shipped together in this fashion. It doesn't really help that [[{{Ephebophile}} Papa Smurf even has]] [[PervertDad that type of interest in Smurfette]]. This is fortunately averted in Sony Pictures' ''Film/TheSmurfs'' film series, as Papa Smurf treats Smurfette like a daughter.
* Cousins Ben and Gwen from ''WesternAnimation/{{Ben 10}}'', thanks to many AwLookTheyReallyDoLoveEachOther moments and meeting many of the requirements for BelligerentSexualTension. Indeed, the pairing is so popular that it's widely speculated the two getting StrangledByTheRedString in the first SequelSeries was an attempt at ShipSinking.
* ''Franchise/TeenageMutantNinjaTurtles'' get this treatment quite a lot, which is known as "turtlecest" in the fandom. The [[WesternAnimation/TeenageMutantNinjaTurtles2003 second animated series]] and the 2007 CGI movie are probably to blame, since they introduced a more complicated dynamic between the mighty foursome and, by the {{rule|ThirtyFour}}s of shipping, any tension can be interpreted in a [[UnresolvedSexualTension sexual]] way.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Twilight Sparkle and her brother Shining Armor were very close when Twilight was a filly. In addition, Shining Armor is introduced in the episode where he is getting married. Twilight takes the news...poorly.
--->"[[DoubleEntendre Like two peas in a pod, we did everything together]]."
** One {{Wild Mass Guess|ing}} is that Applebloom is the ''daughter'' of Applejack and Big Macintosh instead of their sister. This is not helped by the packaging of one toy declaring that Applejack lives on Sweet Apple Acres with her husband, Big Macintosh (and her daughters, Apple Bloom [[CriticalResearchFailure and Granny Smith]]).
** Celestia/Luna, a.k.a. "[[IdiosyncraticShipNaming Princest]]", is the third most popular ship involving the princesses[[note]]The first and second being [[MentorShip Celestia/Twilight]] and Luna/[[LauncherOfAThousandShips Twilight]][[/note]]. Granted, they're [[PhysicalGod goddesses]]--incest is pretty common no matter [[Myth/ClassicalMythology what]] [[Myth/NorseMythology pantheon]] you're looking at.
* ''WesternAnimation/GravityFalls'' has a following for the Dipper/Mabel pairing, due to Dipper constantly being worried and protective of his sister, particularly when it comes to her romantic endeavors. That the twins share a bedroom and in general are very comfortable with touching, hugging, and holding hands with each other gives more basis for fans of this pairing. It has earned the nickname "Pinecest" due to the last name of the two being Pines. So much so that series creator Alex Hirsch has poked fun at it on the official Gravi-Team Falls Website/{{Tumblr}}:
-->"For ages now I have lurked in anonymity, hiding in the shadows of the internet, watching as you've GIF'ed our jokes and shipped our characters and done unspeakable things to my dear Pines Twins. You...you've got some issues, Tumblr. We're all worried about you."
** [[spoiler: Once it was revealed that [[TheReveal Grunkle Stan has a twin brother]], they received similar treatment, with their ship name being "Stancest".]]
* The Twins from ''WesternAnimation/{{Superjail}}'' have somewhat of a fanbase that interpret them as incestuous, based off their narcissism and closeness to each other. Certain lines (such as their "date" joke from an early episode) fueled the shipping, although the vague [[RapeAsComedy porn incident that traumatized them]] has been used by supporters ''and'' detractors of the ship to prove or disprove the dynamic being canon.
* It's been a common joke that the ComicBook/WonderTwins are incestuous. This was referenced to in one of the ''The New Adventures of the Wonder Twins'' shorts by Creator/AdultSwim, where Marvin mistakes them for watching porn together.
* ''WesternAnimation/TheAmazingWorldOfGumball'' has Gumball mostly being shipped with his family especially Darwin and Nicole.
