->"''If you're tired of beating around the bush, why not shake the family tree? A hot cousin might fall out.''"
-->-- '''Creator/StephenColbert'''

Romantic/sexual relationships between cousins are a phenomenon that has been more accepted in some cultures and eras than others. [[ValuesDissonance A great many cultures today accept it,]] including a majority of the industrialized world. Marrying one's extended relatives (which is technically known as ''clan endogamy'') [[http://www.upi.com/Science_News/2013/03/18/Fossil-hints-at-human-inbreeding/UPI-89081363654130/ seems to have been common in human evolutionary history]], since hominids usually lived in small nomadic bands with few available sexual partners. At the other end of the spectrum, much of the modern U.S.A. considers cousin marriage completely taboo, so HilarityEnsues at the very mention of it. People from backwoods areas (especially the Appalachian Mountains) are often the [[AcceptableTargets preferred butt of many bad jokes]] as well as occasional bits of SelfDeprecatingHumor for the alleged prevalence of Kissing Cousins in their culture. Despite the taboo, cousin marriages are legal in about half the states in the U.S.A., though not as much in the backwoods areas and more in the modern industrialized states, the opposite of what one might expect from hearing all those jokes. Legal or not, these marriages are still not very common due to the lingering cultural taboo.

Some cultures distinguish between ''parallel'' cousins -- one's mother's sister's child or father's brother's -- and ''cross'' cousins -- mother's brother's or father's sister's. Cultures in which a parallel cousin is taboo often regard the cross cousin as the best possible choice of a spouse, since the marriage will strengthen bonds among members of the bloodline and ensure that property remains in the family.

Most of the origins of the cousin marriage taboo are not inherently religious; the ancient Hebrew patriarchs demonstrably had no problem with cousin marriage at all (Isaac married Rebekah, his first cousin once removed). The largest Christian denomination, the Catholic Church, allows even first cousins to marry with special dispensation. First-cousin marriage is perfectly fine under Islamic law and some Middle Eastern and Central Asian cultures actively encourage it. Hinduism, Buddhism, Confucianism, and Asian animist traditions have little to say against cousin marriages either.

One culture in which clan endogamy was primarily tabooed was medieval Europe; this prohibition extended as far as third cousins and included in-laws. In a chronically violent culture that put a far higher value on [[ThickerThanWater tribal and dynastic bonds]] than we do today, this was much more about trying to mitigate warfare by extending people's social networks than preventing inbreeding. This led to royal or noble families seeking to end [[CycleOfRevenge blood feuds]] by marriage alliances often needing dispensation from the Church to marry -- as, for instance, Henry VII and Elizabeth of York at the end of the Wars of the Roses. (Coincidentally, it was Henry VII's son Henry VIII who put an end to this in England by breaking from the Catholic Church: The Church of England notably omitted first cousins when listing which relatives were covered by incest prohibitions.)

This was also the case in China, in a historical period analogous to that of feudal Europe; nobles were explicitly banned from marrying ''any'' person that could trace their paternal lineage to the same historical tribe (effectively, anyone with the same family name). This was then extended to all social classes after the unification of the Chinese empire; people bearing the same surname were forbidden to marry even if they were not related at all. However, cousins with different surnames were allowed, and in many cases encouraged, to be paired together to strengthen the alliance between two clans during said period. Linguistic remnants of this tradition may still be found in some areas in Southern China, where the form of address used for one's mother- and father-in-law may also be used to address one's uncle and aunt.

Thanks to the discovery of the laws of genetics a fairly modern part of the taboo against cousin marriage is the perception that this form of inbreeding results in heightened risk of offspring with genetic disorders like hemophilia or albinism. A [[http://www.news.com.au/perthnow/story/0,21598,23792218-2761,00.html study]] in Western Australia discovered that while the risk of a serious defect does rise slightly, the change isn't that dramatic (i.e. a 4% risk for first-cousin parents instead a 2% risk for unrelated parents, roughly equivalent to the risk of birth defects in children conceived by women age 35 and older as compared to children conceived by women under 35) Please note, however, these statistics apply only to first cousins: any couples more distantly related are likely to be as genetically dissimilar as randomly paired individuals from the general population (how many of your third cousins do you even ''know''?).[[note]]On the other hand, getting any closer than first cousins is quite dangerous, because relatedness works on an exponential scale. An uncle-niece pair share 1/4 of their genes as compared to 1/8 for first cousins, and full siblings on average share 1/2 their DNA.[[/note]] And the first-cousin marriages studied were one-time occurrences, those statistics don't cover [[TangledFamilyTree an entire family tree doing it for generations]] like has been seen in certain [[RoyalInbreeding aristocratic populations]]--repeated, exclusive endogamous marriage is likely to have [[RoyallyScrewedUp more serious genetic consequences]].

Expect some ''strong'' ValuesDissonance between the media from the US and other countries, and between certain modern works and works from the nineteenth century and earlier, when the taboo was sometimes non-existent or even inverted. Full scholarly debate on why some cultures would forbid cousins, or even specific types of cousins, to marry, while others ignore or even encourage it, rages on, and lies beyond the scope of this wiki.

According to both Oxford's and Merriam-Webster's Dictionaries, the original definition of ''kissing cousins'' was simply a relative known well enough to be given a kiss in greeting, although this has fallen by the wayside.

!!Examples

[[foldercontrol]]

[[folder:Anime & Manga]]
* A lot of HaremSeries have a cousin among the haremettes.
* In ''LightNovel/SwordArtOnline'' the player, Leafa, is actually Kirito's cousin Suguha, though they were raised as siblings, Suguha became interested in Kazuto after finding out they weren't siblings, just cousins. Suguha tried to give up on him since he was obviously in love with his girlfriend Asuna, so she, as Leafa, began to develop feelings for Kirito. Suguha never knew Kirito and Kazuto were the same person until Kirito tells her he has to find Asuna and she is naturally shocked and upset that she fell in love with her cousin twice and the feeling isn't mutual.
* In ''AyashiNoCeres'', Kagami claims that there's been a lot of this in the Mikage family line, although it's worth mentioning the context seriously calls his credibility into question: he's trying to provoke Ceres into emerging from his cousin Aya by coming on to her, taunting her with this claim, and attempting (or at least pretending to attempt) to rape her.
* [[{{Tsundere}} Ayano]] and [[JerkWithAHeartOfGold Kazuma]] from ''LightNovel/KazeNoStigma'' are ''second'' cousins, with [[ShipperOnDeck Ayano's father]] trying to pair them up.
* ''Manga/ElfenLied'' has Yuuka and Kouta, complicated by a LoveTriangle with a girl who alternates between homicidal and amnesiac.
* In ''Anime/ThisUglyYetBeautifulWorld'', Takeru Takemoto's cousin, Mari Nishino, is in love with him.
* Shiratori Ryushi and Aoba Kozue, the OfficialCouple in the romantic-comedy ''Manga/{{Mahoraba}}'', are second cousins.
* In ''Anime/NerimaDaikonBrothers'', Hideki has a crush on his cousin Mako, who in turn is attracted to her cousin (and Hideki's brother) Ichiro.
* In ''Manga/BladeOfTheImmortal'', Kagehisa Anotsu's true love is the swordswoman Makie Otonotachibana. Her grandmother was the younger sister of Anotsu's grandfather, which makes them second cousins.
* In ''Manga/{{Naruto}}'' spin-off series ''Manga/RockLeesSpringtimeOfYouth'', Neji is implied to have more than just familial affection for Hinata, because there is a scene where he imagines the story of ''Theater/RomeoAndJuliet'', in which he casts himself as Romeo and Hinata as Juliet. In his fantasy, they're called ''Nejio and Hinaette'' and look at one another with sparkles in their eyes, before they run towards each other and embrace lovingly. In the same series, he gets so angry when he hears about Hinata trying to date Naruto, that he attacks Hinata in fury, and it's not just the big brother instinct anymore, but plain jealousy. Bear in mind that their fathers were identical twins, meaning that Neji and Hinata are even more closely related than would normally be the case for first cousins.
-->'''Neji:''' Never... you and Naruto... doing things like that... it's... ''[[UnstoppableRage an infamy]]''!
** There is also [[http://www.mangareader.net/rock-lees-springtime-of-youth/20/8 issue 20]], where Neji gets a severe nosebleed when he hears about Hinata's breasts getting even bigger than they already were.
** [[http://jackoffjill21.tumblr.com/post/44239026098/i-think-neji-just-came This.]]
** He also acts like [[LovableSexManiac a pervert]] towards the female characters in the ''Road To Ninja'' alternate universe movie, including Hinata. Preview scenes and the trailer show that he acts like this ''especially towards Hinata''.
* Hanamori Pink did a short story called ''Cherry ♥ Blossom'' where the main couple were cousins. In fact, it's ''because'' they're cousins that they're able to save ([[SeriousBusiness the love lives of]]) their entire school by calling on the powers of their ancestors. It was published with other short manga in Japan, but the only official English translation is as an extra in the last volume of ''Manga/MermaidMelodyPichiPichiPitch''.
* Amusingly when ''Anime/SailorMoon S'' was {{Macekre}}d in TheNineties English dub, Cloveryway turned Haruka and Michiru into cousins to try and eliminate the [[HideYourLesbians lesbian content]]. Unfortunately (for them) they didn't remove the subtext successfully, [[DubText rendering them lesbian kissing cousins]]. (It's speculated that this ''may'' have been a result of GettingCrapPastTheRadar.)
* Likewise when {{Nelvana}} {{Macekre}}d ''Anime/CardcaptorSakura'' into ''Cardcaptors'' they made two of Sakura's classmates who were clearly fond of each other, with a snarky, cute relationship, into cousins. Whereas they removed the fact that [[ChildhoodMarriagePromise Meiling]] and Syaoran were cousins by changing Meiling's surname to Rae.
** Sakura and Tomoyo are ''second'' cousins, although their mothers, Nadeshiko and Sonomi (respectively), definitely fell into this trope. Or at least Sonomi ''wished'' they did.
* In ''[[Literature/HalfPrince 1/2 Prince]]'', Rose kisses [[AttractiveBentGender Prince]] in [[MassivelyMultiplayerOnlineRolePlayingGame the game]]. Eventually it's revealed that Rose's player is actually her cousin.
** And by cousin you mean that she's her mother's older sister's husband's uncle's third daughter.
* PlayedWith in ''Manga/FruitsBasket''. Several of the couples consist of two members of [[BigScrewedUpFamily the Sohma clan]], and they often call one another "cousins", but the family is roughly the size of a small town. Considering how small the families tend to be (and that none of the characters' parents are ever implied to be siblings), the couples are probably only distantly related; they just call each other "cousins" because it's simpler than "third cousin twice removed".
* Crown Prince Kouen gets some ShipTease with his first cousin Princess Hakuei in ''Manga/MagiLabyrinthOfMagic''. Their respective younger siblings seem to be well aware that there's something going on between the two. Although it's not considered unusual, since [[ValuesDissonance their culture is based on Ancient China]].
* ''Manga/AngelDensetsu'' subverts this in a {{Flashback}} arc that details how Kitano's parents met. Midori is involved with her cousin and childhood friend, Chuji, who has a [[UnknownRival one-sided rivalry/obsession]] with Ryuichiro, and is most definitely AxCrazy. She insists that Chuji isn't evil, and asks Ryuichiro to defeat him in order to open his eyes. That really won't work, since he ''is'' evil now, and even considers [[KavorkaMan Midori as just another easy girl]]. After he tells Ryuichiro this, Ryuichiro angrily lays him out in ''one attack'', after being [[TheJuggernaut repeatedly struck with bronze knuckles and shrugging them off]]. Midori overhears and realizes the truth, culminating in the more heartwarming relationship between her and Ryuchiro.
* In ''Manga/{{Narutaru}}'', Shouko Fukuyama has these feelings for her cousin Kyouji. Hell, she has it ''bad'' for him; she's about 13 years old and wants to bear his children. She has an ItsAllJunk hissy fit after being told off by his old crush Jyun. Eventually, Kyouji, who had been comatose for years, dies, and Shouko is all alone... until she sees him after he turned into a..."Virgin Princess" and vows to keep on loving him.
* In the manga ''Manga/SakuraDiaries'', the main character Touma's younger cousin, Urara, is constantly trying to sleep with him and keep him away from other women.
* By a similar token, much the same happens in the manga ''VisualNovel/GakuenHeaven''... except there, the cousin isn't the DesignatedLoveInterest and doesn't factor into the series' BettyAndVeronica equation at all.
* It's been mentioned in a ''Anime/CodeGeass'' [[AllThereInTheManual Sound Episode]] that Suzaku Kururugi was engaged to his cousin Kaguya Sumeragi when they were children. Kaguya later decides that she is married to Zero, Suzaku's mortal enemy. [[spoiler: What makes it particularly funny is that Suzaku eventually ''becomes'' Zero, though we don't know if Kaguya knows ''that''.]]
* In one of the earlier cases of ''Manga/DetectiveConan'', the killer's motive for killing his grandfather, etc, was he fell in love with his cousin, and the older man forbid them to marry. The killer's parents were also cousins, and the patriarch reluctantly agreed their marriage.
* Suzuho in ''LightNovel/MacademiWasshoi'' is Takuto's cousin, and naturally one of the haremettes fighting for his affection.
* ''Anime/{{Macross}}''/''Anime/{{Robotech}}'' Minmay and her cousin (no blood relation) Kaifun.
* In ''Manga/BlackButler'', Ciel is [[ArrangedMarriage engaged]] to his cousin, Elizabeth. They get along quite well, in fact Elizabeth is one of the few things that Ciel seems to care about.
* Which one of the girls in ''Anime/OnegaiTwins'' is related to Maiku? In the manga, ''both'' of them. The one who isn't his sister turns out to be his cousin. They still get together, and if being cousins is an issue, they never say so.
* In ''Manga/VenusVersusVirus'', Sumire's male cousin, Riku, likes her. He's like ten years old, and she's fourteen.
* Sachiko Ogasawara in ''[[LightNovel/MariasamaGaMiteru Maria-Sama Ga Miteru]]'' is intending to marry her cousin Suguru after she graduates.
* In a filler episode of ''Manga/ShugoChara'', Amu admits that her cousin Shuu was her first real crush.
* In the manga of ''LightNovel/ZeroNoTsukaima'' the Prince of Albion, Wales, and the Princess of Tristian Henrietta are cousins who are in a secret affair (Long distance). Their love is cut short when [[spoiler:Wales is killed.]]
* In ''Anime/MaiOtome0Sifr'', it is revealed that Sifr is the daughter of the King of Windbloom's brother, and it is strongly implied that she eventually marries the King's son, Bruce.
* Masahiko and Shion from ''Manga/FamilyCompo'' are cousins and there's often a sense attraction between the two. The manga starts with Masahiko saying Shion is cute, before he learns she's his cousin. Oddly the series keeps on swaying between Masahiko being Sora's and Yukari's parent figures, and whether Shion and him are LikeBrotherAndSister or are full KissingCousins.
* The protagonist and his second-cousin in ''Hanayashiki no Juunintachi''.
* In ''TenYoriMoHoshiYoriMo'', Tadaomi's father and Mio's dead mother were siblings, so a Tadaomi/Mio match-up would be this. Tadaomi wants it ''badly'' to happen, but Mio does not.
* ''{{Manga/Bleach}}'': Pure-blood Quincies are expected to accept endogamous {{Arranged Marriage}}s to prevent contamination of bloodlines even if it means marrying cousins. The Ishida [[TheMatchmaker matriarch]] engaged her son Ryuuken to his cousin when they were both teenagers. [[spoiler:[[TheStoic Ryuuken]] and [[GenkiGirl Masaki]] cared about each other as family but were reluctant to marry because they knew they were romantically [[NoSparks ill-matched]]. Not only was Ryuuken not Masaki's type, he was also more [[ChildhoodFriendRomance attached]] to [[BodyguardCrush Kanae]] than he was [[UptownGuy allowed to be]].]]
* ''Webcomic/AxisPowersHetalia:'' Downplayed -- Austria is the cousin of Germany and Prussia, and he gets a ''lot'' of HoYay with them, though the OfficialCouple is Austria/Hungary. He allows Germany to practice sexual activities with him, to prepare Germany for Italy.
** Having a cast of LoadsAndLoadsOfCharacters based on ''countries'', most of whom are related in some way, makes this and other forms of IncestSubtext fairly common in the series (one of the {{Squick}} factors that drives some people away from the fanbase). Generally, however, it remains as downplayed as the above example - i.e., Prussia and the Holy Roman Empire are both children of Germania, and as Germany is Prussia's brother and Italy is Holy Roman Empire's grandson, this makes Italy something like Germany's second grandchild once removed (as well as his romantic interest)... This mostly results from the characters' TangledFamilyTree, though, and may not have been intentional.
* ''Manga/ACruelGodReigns'': William has a fling with his second cousin, and it is implied that [[spoiler:Lilia may have cheated on Greg with her second cousin]].
* ''Anime/HaiyoreNyarkoSan'': Cuune wishes she and her cousin Cuuko were this. [[AllLoveIsUnrequited Cuuko has obsessions of her own]].
* In the YuriGenre series ''Manga/SakuraTrick'', the BetaCouple Kotone and Shizuku are cousins. While we don't know how far they go, at least they literally had TheBigDamnKiss.
* In ''HanasakeruSeishounen'' [[spoiler: Rumaty and Kajika are unknowingly this. They do not actually get together in the end, but before Kajika and Lee Leng's RelationshipUpgrade, the two are the closest out of all of Kajika's LoveInterests.]] Bonus points for being each other's [[FirstKiss first kisses]].
[[/folder]]

[[folder:Comic Books]]
* {{Marvel}} superhero Black Bolt, the king of TheInhumans, is married to his cousin Medusa. Sorta justified: due to the limited gene pool of the Inhumans, just about every two-Inhuman marriage involves cousins.
* MarkMillar's post apocalyptic ''{{Wolverine}}'' story "OldManLogan" features a future were [[Comicbook/IncredibleHulk Hulk]] and cousin [[SheHulk She-Hulk]] have bred and produced inbred offspring. This is all due to her being the only woman able to "Take the pace" of Hulk sexually. Hulk and She-Hulk are both radioactive too, which probably didn't help...
** Not the first time romantic/sexuality thing has been brought up between these two as some of Fixit's dialogue with her implies he's more than game.
** It bears mentioning that there were implications that the relationship wasn't exactly... ''consensual''.
* {{Superman}}'s future daughter engages in [[http://25.media.tumblr.com/tumblr_lre8o6TFW51qkwdf0o1_400.jpg a literal example]] in a SilverAge {{Elseworld}} story taking place in the future. (For those who don't know the {{Superman}} mythos, Lucy and Lois are sisters, which makes Lucy and Jimmy's son the cousin of Lois and Clark's daughter. Apparently, that doesn't bother Lola ''or'' Jimmy Jr, let alone their parents, happily watching them make out. The issue itself makes ''no'' mention of them being cousins, with the main obstacle to their happiness being ItsNotYouItsMyEnemies. [[spoiler: They do live HappilyEverAfter in the end]]. As an {{Elseworld}}, it doesn't really count, but still... how this got [[GettingCrapPastTheRadar past the radar]] is a mystery.)
** The Man of Steel himself apparently had such feelings [[http://i6.photobucket.com/albums/y246/FireFox516/Random%20Crap/SupermanandKara.jpg for his cousin Kara]] ({{Supergirl}}). In ''that'' one, Kara tries to find Supes a girlfriend. After many failed attempts, we get the panel above, which seems to make it perfectly clear that the law is the only thing stopping them from pursuing a relationship (maybe they [[ValuesDissonance minded a lot less in the 60s?]].) Eventually, Kara fixes Supes up with a girl that is nigh identical to herself, but older, and they hit it off. [[spoiler: Unfortunately, it turns out yellow sun is her Kryptonite, and he can't leave Earth unprotected, so they must part.]]
** Also, from the same source as LexLuthor stealing '''forty''' cakes[[note]]That's as many as four tens. AndThatsTerrible.[[/note]] comes Kara and Clark [[http://30.media.tumblr.com/tumblr_lvzhjklUch1r2ntbyo1_500.png deserving a rest]]. Maybe it's just hard to make her look unsexy, but... that looks far from innocent, and the repetition, though intended to drill the definition into a kid's mind, ''really'' makes it sound like she is saying "We deserve a rest, nudge nudge wink wink," and the big blue boy scout [[ObliviousToLove just isn't getting it yet]].
** In yet another SilverAge Superman story, Clark has Kara disguise herself as a superheroine from another dimension, and she and Supes proceed to have makeouts (in ''front'' of Lois), all to fool some dim alien invasion. She was explictly underage at the time, too. Yeesh.
* The ultimate desire of MarvelComics superhero [[ComicBook/AgentsOfAtlas Namora]] has been shown to be her cousin [[SubMariner Namor]].
** Namor's late wife Dorma was also his cousin.
** Namorita (daughter/clone of Namora, and therefore cousin of Namor) was in love with Namor at one point, though it was unrequited.
* Magazine/{{MAD}}'s ''Monroe'' was once visited by his punky Scottish cousin, and they made out a few times. She decided she didn't want to see him anymore because of he was freaky with his "finger-skateboards", but as he said, at least he got to "make oot" that summer.
* In the XWingSeries, Plourr Illo was engaged to her cousin since childhood. In the arc where she returns to her homeworld and takes up the reins, she's shown resisting the idea of marrying him, but since he shows a number of her traits - lots of courage, love of fighting and freedom, disdain for tradition for tradition's sake - she warms up to him. It's never shown whether they actually get married at some point.
* In the ''ComicBook/DouweDabbert'' story ''Florin the Loafer'', count [[MeaningfulName Justus van Bottericke]] attempts to force his cousin Gwendoline to marry him, because if she does not, he will lose the rights to his title.
* In Archie's ''ComicBook/SonicTheHedgehog'' comic, Knuckles the Echidna and his girlfriend Julie-Su are actually distant cousins, but neither one is aware of it, and it's not directly acknowledged anywhere in the series. [[http://amomentofarchiesonic.tumblr.com/post/20358543852/guest-submission-original-author-comment-went They did, however, release a family tree at one point,]] forgetting that their family tree closes back in on itself.
* Helene and Franz from a story by Creator/WilhelmBusch. Despite him being a Catholic priest.
[[/folder]]

[[folder: Fanfiction]]
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfiction, [[http://www.fimfiction.net/story/66500/maternal-instinct Maternal Instinct]], the Changeling royal family, the House of Roachanov, has a reputation for practicing royal intermarriage, much like the European monarchies of old, ironic as the culture is predominantly of ImperialJapan. The Crown Princess, Pupa, is already set to marry her first cousin, Prince Morphin.
* There's a fairly large following in the PhineasAndFerb fandom for the pairing of Marie Flynn (daughter of Phineas and Isabella) and Thomas Fletcher (son of Ferb and Vanessa)...even in universes where Phineas and Vanessa are half-siblings. And even in the more traditional worlds, there's still frequently LampshadeHanging about "Isn't she your cousin?" "[[InsistentTerminology Step-cousin]]." All in all though, [[PortmanteauCoupleName Thomarie]] is pretty cute...even if Marie is as [[ObliviousToLove oblivious as her father.]]
* ''WesternAnimation/Ben10'' has a rather large following for Ben and Gwen pretty much since the first series. This can be connected to the BleachedUnderpants history of the original draft of the show in which Ben and Gwen were not relatives but rather in the same school class.
[[/folder]]

[[folder: Fairy Tales]]
* Several of Madame D'Aulnoy's FairyTale couples are first cousins -- a natural consequence of their both having to have RoyalBlood and reflecting the royal families of their day. Such as ''[[http://www.surlalunefairytales.com/authors/aulnoy/1892/princessbelleetoile.html Princess Belle-Etoile]]'' and ''[[http://www.surlalunefairytales.com/authors/aulnoy/1892/beeorangetree.html The Bee and the Orange Tree]]''
* In the first written version of "Literature/BeautyAndTheBeast", Beauty and the Beast turn out to be ''double'' first cousins, their fathers being kings and brothers, and their mothers fairies and sisters.
* The French fairy tale ''[[http://www.mythfolklore.net/andrewlang/040.htm The Little Green Frog]]'' features a second cousin couple, Prince Saphir and Princess Serpentine. Their fathers are first cousins.
* In many Arab fairy tales, reflecting common practices, a woman is normally expected to marry her first cousin. (One example of such a couple is found in ''[[http://www.mythfolklore.net/andrewlang/218.htm The Story of Dschemil and Dschemila]]'', which comes from Libya.) This causes serious complications when she falls in love with another man; some tales have men forced to leave a tribe lest it happen. However, some first cousins graciously concede; this is often resolved by the new bridegroom [[DoubleInLawMarriage offering the first cousin his own cousin.]]
[[/folder]]

[[folder:Film]]
* Colin, in ''Film/TheSecretGarden'', wants to marry his cousin Mary when they grow up so that they can always be together. Mary is amused but uninterested. Colin's response is a jealous loathing of Dickon, the servant boy who helps them in the titular garden, with whom he suspects Mary of falling in love. In one film adaptation, their mothers are stated to be identical twins, thus making this even iffier genetically, since the offspring of identical twins are genetic half-siblings (assuming the other parents involved to not also be identicals, and to be two different people).
** In the 1987 Hallmark adaptation adult Colin (portrayed by a very young looking Colin Firth) proposes to Mary at the end and she accepts.
* In ''Film/TheGodfather Part III'', Micheal’s daughter, Mary, and his nephew, Vincent, are in love. Michael is against their relationship, but Mary's mother, Kate, is not.
* In the Victorian farce ''TheWrongBox'', Michael tries to resist his attraction to his cousin Julia:[[note]]It turns out they were both adopted; her parents were missionaries and were eaten by their congregation.[[/note]]
-->'''Michael:''' We both know what kissing leads to, and if I may be blunt, our children would be idiots."
-->'''Julia:''' Why, is there insanity in your family?
* In ''Film/CruelIntentions 2'', the girls in the shower claim to be KissingCousins (even though in real life they were played by real-life [[{{Twincest}} identical twins]], making the scene an almost-crossover with TwinThreesomeFantasy).
* Dar and Kin in ''Film/TheBeastmaster''. It's actually achieved through FridgeLogic; their relationship to each other is never noted at all in the film after the reveal that Dar is the son of Kin's uncle the King, and they don't see any problems in a romantic relationship by film's end.
* In ''Film/{{Tombstone}}'', Doc Holliday tells Wyatt Earp that as a teenager he fell in love with his first cousin; she entered a convent over their affair.
* In ''The Yards'', Leo, the main character, had a relationship with his cousin Erica when they were younger. There is romantic subplot between the two throughout the movie.
* In ''Film/RomyAndMichelesHighSchoolReunion'', Michele lost her virginity to her cousin Barry.
* Disney/{{Bambi}} and Faline in the original books. The movie adaptation averts this, though some licensed books refer to them as cousins.
* The main character in ''Film/BarryLyndon'' courted his cousin, which was a lot more common in that day.
* The 2009 film ''Film/TheYoungVictoria'' is about the early life of QueenVictoria and her marriage to Prince Albert, her first cousin.
* In ''Film/MeanGirls'', Karen talks about what a good kisser her cousin is.
--> '''Karen''': Yeah, but... he's my ''first'' cousin. Like, you have your cousins, and then you have your first cousins, and then you have your second cousins... \\
'''Gretchen''': No, honey, uh-uh. \\
'''Karen''': That's not right, is it.\\
'''Gretchen''': That is ''so'' [[WrongOnSoManyLevels not right.]]
* In ''Disney/TheLionKing'', FridgeLogic dictates that Simba and Nala must be either cousins or half-siblings because Scar and Mufasa are the only adult male lions in the pride.
** The sequel defies this by specifically mentioning twice that Scar is ''not'' Kovu's father, though fans still speculate. Kovu was meant to be Scar's son but then they noticed that'd make Kiara and Kovu cousins.
* The romance between Heather Mason and Vincent Cooper in ''Film/SilentHillRevelation3D''. In the first ''Film/SilentHill'' film, Heather's biological mother Dahlia was the sister of the villain Christabella. In ''Revelation 3D'', Vincent is the son of the villain Claudia, who is Christabella's sister. Therefore, Dahlia and Claudia are also probably also sisters and Heather and Vincent are probably cousins. It could be possible, however, that Dahlia and Claudia could be unrelated, if one were only a maternal half-siblings (uterine) and the other were only a paternal half-sibling (agnate/cosanguine). It's likely, however, that the writer of the second film missed the fact that Dahlia and Christabella were sisters in the first film. It's not the only {{Retcon}}.
* Brought up humorously by Daisy in ''Film/TheGreatGatsby'' when her cousin Nick asks her to visit him [[spoiler: to reunite with Gatsby]] and when she arrives, she discovers his house is full of flowers [[spoiler: courtesy of Gatsby]]. She murmurs he must be in love with her.
[[/folder]]

[[folder:Literature]]
* Multiple books by Creator/JaneAusten have examples of this.
** In ''Literature/MansfieldPark'', the main character, Fanny Price, and her cousin Edmund Bertram.
** Anne Elliot in ''{{Literature/Persuasion}}'' is wooed by her cousin (and her older sister wants to marry that same cousin). However, cousin in this case means a male relative who might actually be quite distant.
** In ''Literature/SenseAndSensibility'', Colonel Brandon's first love was his cousin Elizabeth, as he confides to Elinor Dashwood.
** ''Literature/PrideAndPrejudice'':
*** Mr. Collins is a cousin of some sort to the Bennet sisters, and comes to their house with the intention of marrying one.
*** Lady Catherine de Bourgh wants her nephew to marry her daughter.
* In ''Literature/TheHeroesOfOlympus'' by RickRiordan, it is mentioned that unless you have the same godly parent, it isn't creepy for two demigods to have a relationship.
* In Jade Green, Charles lusts for his cousin Judith, and is secretly planning on raping and killing her after she rejects her advances, much like the the title character herself.
* In ''Literature/TheSilmarillion'' by Creator/JRRTolkien, the Elf Maeglin was in love with his first cousin Idril Celebrindal, who is [[{{Squick}} squicked]] by this, for "the Eldar wedded not with kin so near, nor ever before had any desired to do so."
** Also, Ar-Pharazôn, the last King of Númenor, married his first cousin, Tar-Míriel, against her will.
** Aragorn and Arwen are first cousins several-times removed, as Arwen's uncle also happens to be an ancestor of Aragorn's many, many generations up the tree.[[note]]Elrond and Elros were both {{Half Human Hybrid}}s. Elros identified with his human side and became the first King of Númenor, whose line descended to the Kings of Arnor and Gondor. Elrond identified with his elven side and got their functional immortality.[[/note]]
** Galadriel and Celeborn are second cousins - Galadriel's maternal grandfather and Celeborn's paternal grandfather were brothers.
** Sam Gamgee and his wife Rosie Cotton are third cousins. Sam's great-grandmother Rowan was the older sister of Rosie's great-grandmother Rose.
** Merry Brandybuck's parents Saradoc and Esmeralda are second cousins. Saradoc's grandmother Mirabella and Esmeralda's grandfather Hildigrim were siblings (both children of Gerontius Took and Adamanta Chubb). Merry marries his third cousin Estella Bolger, who is the great-granddaughter of Hildibrand Took, another of Gerontius' and Adamanta's many children.
* Even besides the NotBloodSiblings romance in ''Literature/WutheringHeights'', there are, not coincidentally, two subsequent cousin-cousin relationships.
* In Felix Salten's ''Literature/{{Bambi}}'', Bambi and Faline are cousins (their mothers are sisters).
* In the 1818 version of ''{{Literature/Frankenstein}}'', Victor Frankenstein and his fiancée, Elizabeth Lavenza, are cousins who also happen to have been raised in the same household. In the 1831 version, Elizabeth was adopted rather than being related to Victor, but the two were still raised as siblings.
* A central part of the plot in ''Literature/OneHundredYearsOfSolitude'' is the fact that the founders of the Buendía clan were cousins, and therefore they feared the family would sooner or later breed monsters if they ever in-bred from that point on. Despite all efforts, [[IncestIsRelative it happens anyway]].
* LouisaMayAlcott's has two books with examples of this.
** In ''[[Literature/EightCousins Rose in Bloom]]'', the only people that the heroine Rose even ''considers'' marrying are three of her seven male cousins, [[ShelteredAristocrat Archie]] (who [[BetaCouple falls for Rose's lady-in-waiting Phebe]]), [[TroubledButCute Charlie "the Handsome"]] and [[NiceGuy Mackenzie, aka Mac]]. Rose's guardian, Uncle Alec, explicitly says that he does not approve of cousins marrying, while her aunt Clara--overheard and tactlessly quoted by yet another cousin--holds that Rose should marry one of them "to keep the money in the family." [[spoiler: After Charlie dies, Rose falls for Mac and marries him, while Archie and Phebe finally overcome the family veto to their relationship.]] As a bonus, Archie's 12-year-old brother Jamie gives Rose a love declaration at some point, which she rejects not because he's her cousin, but because she sees him as JustaKid.
** In ''[[Literature/LittleWomen Jo's Boys, and How They Turned Out: A Sequel to "Little Men"]]'', Jo and Fritz's younger son, Teddy, mentions he wants a sweetheart like all his friends and that he asked cousin, Josie, first.
* In ''Literature/TheMoonstone'' by Wilkie Collins, Rachel's has two suitors, both are her first cousins.
* In the ''Literature/KushielsLegacy'' series by Jacqueline Carey, distant royal cousins (his father is her great-grandfather's brother) Imriel and Sidonie fall for each other. Hard. However, their relatives (and the nation at large) aren't so much annoyed at the idea of relatives marrying so much as they are annoyed that Imriel's mother tried to take over the kingdom (twice, orchestrating an invasion the first time around) and at least some of the populace (mostly the ones still healing the scars from the invasion) thinks Imriel would do the same.
* Mercedes and Ferdinand in ''Literature/TheCountOfMonteCristo''.
* The protagonist of the novel ''Literature/KungFuHighSchool'' is an example of this.
* In ''{{Literature/Rebecca}}'' the titular dead wife and her cousin, Jack Favell, were lovers. This relationship is presented to further underline Rebecca's depravity.
* The Wilkes and Hamilton families in ''Film/GoneWithTheWind'' have the tradition of cousins marrying each other. The text makes it clear that multi-generational inbreeding is the main reason for Melly's [[IllGirl frail health and physique]].
* The ''Literature/SixteenThirtyTwo'' series has fun with this trope. The locals see nothing wrong with cousin marriage. The transplanted Americans are a lot more sensitive about this sort of thing (being from West Virginia, they've heard ALL the "inbred hillbilly" jokes).
* In Creator/AnneRice's ''Literature/LivesOfTheMayfairWitches'' trilogy, 13-year-old Mona Mayfair has a list of the male cousins she intends to sleep with and gets a considerable way down it before going on to other things.
* In ''The Book of Tobit'', it's not clear exactly how closely Tobias and Sarah are related, but their marriage is not only allowed but considered obligatory.
-->''Eat and drink and be merry tonight, for no man is more entitled to marry my daughter Sarah than you, brother. Besides, not even I have the right to give her to anyone but you, because you are my closest relative.''
** Due to the nomadic, tribal lifestyles of the ancient Israelites, this is true throughout the Bible. Jacob married TWO of his cousins, the sisters Rachel and Leah, and also fathered children by their handmaidens.
** Also due to the fact that, in the list of relatives and other people an Israelite man is not allowed to have sexual relations with, "cousin" is conspicuously absent.
* In the young adult book ''Literature/HowILiveNow'' by Meg Rosoff, teenage cousins Daisy and Edmond fall passionately in love. Daisy wonders uneasily for a while "if that's the feeling your supposed to have when your cousin touches a perfectly innocent part of your anatomy that's even fully clothed". By the middle of the book, she doesn't care. The book treats their romance sympathetically.
* In ''Literature/HarryPotter'', it's implied that [[FantasticRacism purebloodism]] leads to frequent inbreeding. Arthur and Sirius explicitly state that all surviving pureblood wizards are related to some degrees. Particularly after the wholesale slaughter of the second Death Eater war, there are simply so few purebloods left that those who still care about blood purity will have no alternative but to marry their cousins.
** Sirius and Regulus Black's parents, Orion and Walburga, were second cousins.
** Teddy Lupin and Victoire Weasley are fourth cousins once removed.
** Molly Prewett and Arthur Weasley were third cousins through the Black family even before they married.
** Harry and Ginny are implied to be third cousins. The Black Family Tree includes as Dorea Black's husband Charlus Potter, whose information fits with him being James Potter's father.
** After Tonks's Patronus takes a canine form, Harry wonders if she had been in love with Sirius, her cousin once removed, since he was an Animagus who turned into a dog. [[spoiler:It turned out to be Lupin, a werewolf, however.]]
** The Gaunt family is described as "An ancient, in-bred, pure-blood wizarding family living in slovenly conditions in a shack in Little Hangleton." This is supposedly the main cause of poor Merope's "cross-eyed" appearance.
* The corrupt churchman Annias tries to persuade Queen Ehlana to marry her cousin, Prince Lycheas, in the DavidEddings ''[[Literature/TheElenium Elenium]]'' trilogy. She refuses, mostly on the grounds that she can't stand him but also on the grounds that he might actually be her half-brother, given that her father and his mother [[BrotherSisterIncest were a little closer than siblings ought to be.]] [[spoiler: He isn't. Lycheas was actually the son of Annias, which was part of why he was pushing the marriage.]]
* In the King Arthur trilogy that begins with ''[[Literature/TheSpiderwickChronicles The Seeing Stone]]'', the narrator is a medieval teenager (named Arthur) whose family circumstances parallel King Arthur's. He and his first cousin Grace are pretty much planning on a betrothal when they find out that Arthur's parents are really his foster parents and that he's actually the son of Grace's father by a peasant woman -- so they're half-siblings, not cousins, and any thoughts of marriage have to be dismissed immediately. There's close and then there's ''too'' close.
* In Creator/ChristopherMoore's ''Literature/{{Fool}}'', [[spoiler: Pocket]] has running on/off affairs with both [[spoiler: Goneril and Regan, unaware that they're both his first cousins by way of rape]]. Probably wouldn't have stopped any of them if they did know, though. He certainly doesn't seem horrified by it when he does find out. In fact [[spoiler: he winds up marrying the youngest sister Cordelia. Whether she knows about the family connection or not isn't revealed.]]
* Skinflick in Josh Bazell's ''Beat the Reaper'' is a young ''[[TheMafia mafioso]]'' in love with his cousin. The narrator is non-judgmental about this.
* In Tanya Huff's ''The Enchantment Emporium'' Gales, a clan of witches usually (though not always) marry their cousins to keep from diluting the magic inherent in their genes and to keep said magic secret. Furthermore because there are far more more female Gales than male the boys usually "make the rounds" of their age group cousins before settling down. This imbalance between the sexes also leads to a lot of [[RomanticTwoGirlFriendship "close" relationships]] between the Gale girls. One of these, between main character Alysha and her cousin Charlie is particularly focused on in the book.
* The OfficialCouple in ''Literature/PercyJacksonAndTheOlympians'', both being children of the gods, are technically cousins, but this is HandWaved by stating that the gods don't have DNA (and drawing a distinction between dating a child of another god and dating a child of the same god).
** It also make a good deal of sense, given [[IncestIsRelative just what pantheon those gods belong to]].
* In the novel ''Literature/{{Middlesex}}'', the protagonist's parents were second cousins that eventually fell in love, but what they didn't know was that the father's parents were actually [[BrotherSisterIncest brother and sister]], resulting in a rare recessive gene to make their child Calliope (later Cal) born [[{{Hermaphrodite}} intersexed]].
* In ''Literature/JudeTheObscure'' by Thomas Hardy, Jude and his cousin Sue fall in love. It's not a problem at all (unlike everything else in the world.)
** Without spoiling the story, it's a pretty major problem. It's the reason they resist their attraction in the first place which causes so many problems down the line. Though the novel attempts to make the argument that the judgments and restrictions of society are worse than the actions of the characters.
* In the ''Literature/{{Iliad}}'' Achilles and Patroclus are cousins. Whether or not they were kissing has long been a matter of debate.
* An interesting twist is found in the Alfred, Lord Tennyson poem ''Lady Clare''. The titular earl's daughter is engaged to her cousin, Lord Ronald, much to the delight of her nursemaid...who promptly reveals that Clare is actually her own daughter, whom she substituted for the real Lady Clare, who died in infancy. Ronald, as the next male-line heir, ought to be inheriting everything that Clare's father left to her. Clare, horrified that Ronald would be "kept from his due" and married to a peasant, leaves the castle only to run into a bewildered Ronald. She explains everything, and he shrugs it off and says they'll marry anyway, "and you will still be Lady Clare."
* ''Literature/TessOfTheDUrbervilles'' is a rather tragic example. Tess' cousin Alec is pretty much obsessed with her and it leads to [[spoiler: him raping and impregnating her, and her eventually murdering him. Though, as it turns out, his family merely took the d'Urbervilles name and they're not actually related at all.]]
* In ''[[Creator/BeatrixPotter The Tale of the Flopsy Bunnies]]'' Flopsy Rabbit is married to her cousin Benjamin Bunny.
* In ''Literature/The39Clues'', all Cahills are distantly related...
* ''[[Literature/HeraldsOfValdemar Owlsight]]'' has a brief relationship between Darian and (adoptive) double first cousin Summerdance.
* ''Illyria'' by Elizabeth Hand is about the romance between first cousins Maddy and Rogan, whose fathers are twins.
* In ''Nerve'' by Creator/DickFrancis, the protagonist is hopelessly in love with his cousin. She spends much of the story discouraging the idea, though it turns out the feeling is mutual, and she's beginning to come around toward the end.
* In the Literature/NeroWolfe novel ''[[spoiler:The Red Box]]'', Nero deduces that one of the characters is interested in marrying his cousin. [[spoiler:Ultimately, she is revealed as not actually being related.]]
* In ''Literature/CharmedLife'', by Creator/DianaWynneJones, Cat and Gwendolen's parents were first cousins. Chrestomanci explains that when they decided to marry, it caused their family to make a great fuss. "It is, you see, rather a bad thing for cousins to marry when there's witchcraft in the family."
* In the ''Literature/KnightAndRogueSeries'' Michael has a rather serious crush on Rosamund who is his second or third cousin (it never says the exact relation) and who, since they grew up together, sees him as a brother.
* [[Literature/TheElricSaga Elric of Melnibone]]'s betrothed is his cousin Cymoril. He damns himself (and ends up killing her) by accepting [[ArtifactOfDoom the demonic blade Stormbringer]] to rescue her from her [[BrotherSisterIncest brother Yyrkoon]].
* First cousins Richard and Emmeline in Henry De Vere Stacpoole's ''Literature/TheBlueLagoon''. Granted, there was a serious shortage of alternate partners.....
* Georgy and Oliver in ''Literature/SorceryAndCecelia'' by Creator/CarolineStevermer and Creator/PatriciaCWrede.
* Within the Kencyr race of ''Literature/ChroniclesOfTheKencyrath'', it's not uncommon for cousins to marry repeatedly to increase their Shanir gifts and the author has already indicated that the most likely partner for Jame will be her brother, Torisen. Then again, the Kencyr are also noted to have magical healing powers which seem to clear up some of the recessive disorders. Then again, some of the pureblooded families are also starting to experience some side effects such as one character's whose body repeatedly rejects his teeth so that they rot out of his gums and grow back constantly.
* In the ''Literature/{{Babar}}'' books, the title character eventually married his cousin, Celeste. The AnimatedAdaptation changed this particular aspect, making the two unrelated and turning their relationship into ChildhoodFriendRomance instead.
* In the ''Literature/MontmarayTrilogy'', both Sophie and her brother Toby are in love with their cousin, Simon. But neither of them knew he was their cousin when they fell in love with him, but both continue to engage in relations with him after finding out.
* Camille and Thérèse in ''ThereseRaquin'', though their marriage didn't involve much, if any, sexual activity.
* In the ''Bunduki'' novels by Creator/JTEdson, Bunduki and Dawn are adoptive cousins. They end up married.
* Basically being set in a MedievalEuropeanFantasy world, this is prevalent in ''Literature/ASongOfIceAndFire''. The most prominent example is [[MagnificentBastard Tywin Lannister]] marrying his cousin Joanna, and there are several other minor examples mentioned.
** Cersei sleeping with her cousin Lancel becomes a plot point, thanks to how sensitive that information is, with her being the king's widow (and how easy it is to manipulate Lancel if you're aware of it) and how jealous her [[{{Twincest}} incestuous twin brother]] is.
* In ''Literature/InTheTimeOfTheButterflies'', Dede and Jaimito are cousins and her sister Maria Teresa has a brief LoveTriangle between her two cousins, brothers Raul and Berto.
* In ''Literature/ABrothersPrice'', Jerin Whistler and the Princess Rennsellaer find, after downgrading his [[VirginTension virginity status]] to [[TechnicalVirgin technical levels]], that they share great-great-grandmothers making them third cousins. Ren declares that it is distant enough for the relation to be fine and, indeed, [[SuddenlySuitableSuitor that's how it's seen]].
** One of Ren's sisters would rather marry Cullen Moorland, but his mothers were sisters to their father; they are seen as full cousins, and with birth defects and inbreeding being major concerns in this world, especially among the nobility with its fears of being polluted by common blood, she is voted out.
** [[spoiler: Eldest Porter is revealed to be the child of people who are genetically full cousins, but socially considered to be [[BrotherSisterIncest siblings]].]] She's healthy - the onus is on [[VillainousIncest her parents]] for breaking taboo like that. It should be noted that in this world [[GenderRarityValue men are very rare]], and a man marries every sister in a family; the sisters themselves are born of several different mothers.
* In Creator/IsabelAllende's ''Literature/EvaLuna'', when Rolf Carlé comes to America from post-WorldWarTwo Austria, he lives with his uncle and aunt and is attracted to both of his cousins... not only his affections are reciprocated by ''both'' girls, but they actually jump him [[ThreesomeSubtext and they "share" the cousin/lover for their teenage years]], until Rolf becomes an IntrepidReporter and the girls marry local guys. The three still remember these escapades as some of their happiest moments ever.
** Also it's mentioned that the girls's parents ''did'' seriously consider to have him marry one of the girls, "sighing because there was only one if him".
* In the ''Literature/LowlandsOfScotland'' series, Jamie [=McKie=] ends up married to both of his first cousins (not at the same time).
* In UK children's author Malcolm Saville's Lone Pine series, first cousins Jon and Penny Warrender are engaged by the end of the final book.
* In ''Literature/{{Warriors}}'' there are plenty of kissing cousins. And more. Lots more. Needless to say, the family tree is... complex.
* In Creator/AndreNorton's ''Literature/IceCrown'', Nelis asks whether Roane is "ringed" to her first cousin Sandar, which causes Roane to laugh. Though at the end, he explains that he is the queen's first cousin, to show that their connection is not romantic.
* In ''Literature/TheDarkangelTrilogy'' there's a love triangle in which all three participants are cousins. [[spoiler: Two of them didn't know they were related at first, but the discovery has no effect at all on their romance either bad or good - it doesn't seem to be relevant to them.]]
* Gertrude Wentworth and Felix Young in Creator/HenryJames' novel ''Literature/TheEuropeans''.
* ''Literature/{{Seraphina}}'': Staying true to the Western European feel of the setting, first cousins Prince Lucian and Princess Glisselda of Goredd are engaged.
* In DorothyLSayers's ''Busman's Honeymoon'', LordPeterWimsey worries about children because of how his brother's turned out. Harriet points out that his brother married his own cousin; his sister, who married a commoner, has children who are perfectly fine.
* In ''Un grito en las tinieblas; la vida de Zárate Arkham'', the titular character sleeps with her cousin, although both of them were possessed by the spirits of their uncle and his female servant respectively –which make the sex scene a case of double incest.
* Rand al'Thor is worried about this when he considers courting the Andoran Daughter-Heir Elayne Trakand in ''Literature/TheWheelOfTime'' after he learns that he is descended from Andoran royalty on his mother's side, making them distant cousins. He is reassured after an expert on genealogy informs him that if they were both commoners, they wouldn't be considered related.
* In Thai Literature Phra Apaimanee, Sin Samut and Arunratsamee are first cousin.
* In ''Discworld/MakingMoney'', marrying cousins is mentioned as traditional for the [[BigScrewedUpFamily Lavishes]] in order to keep the money in the family, although "occasionally they married outsiders to avoid the whole 'three-thumbs' situation."
* Played with in ''Literature/TheHungerGames''. The Capitol does not approve of Katniss' close friendship with Gale, seeing him as a potential rival to Peeta, so they claim the two are cousins. In the third book President Coin asks Katniss if she wants Gale declared as her new lover, which would make them this trope in the public's eye. Katniss declines.
* ''Literature/TheReynardCycle'': Two of the suggested brides for [[spoiler: King Lionel]] are his cousins by his aunt. No one raises any objections over this.
[[/folder]]

[[folder:Live Action TV]]
* An episode of ''Series/JustShootMe'' involved Nina being pursued by a handsome man who, for some unfathomable reason, she has no attraction to. When he mentions he is also from Colby, Kansas, they discover they are cousins. He's completely disgusted and flees, while Nina is relieved that she's not stopped being attracted to men.
* ''Series/ArrestedDevelopment'' had a recurring storyline about George-Michael's crush on his cousin Maeby [[spoiler: who eventually turns out [[NotBloodSiblings not to be his biological cousin]])]]. Furthermore, when these feelings become mutual, Maeby tries to hide from them by dating a boy from her school, who turns out to ''also'' be her cousin. [[spoiler: Again, not by blood.]] This was mirrored in two storylines in the final season. The first saw Michael Bluth (played by Jason Bateman) thinking that a prostitute was his long-lost sister and hiring her to work at the company; she thought this was a ''PrettyWoman'' situation and started coming on to him. (The prostitute was played by Justine Bateman, who is Jason Bateman's real-life sister.) Then, in the final episode [[spoiler: it was revealed that Lindsay was not actually Michael's biological sister. Upon finding out, she decided to act on a crush she had had for years.]] Additionally, Michael ended up going out with a woman who [[spoiler: suffered from mental retardation on account of her parents being cousins.]] It was a lot funnier and less creepy than this sounds.
* Relatively common in Hispanic {{Soap Opera}}s. During Venezuelan soap ''Carita Pintada'''s pre-premiering the author claimed that the main couple could achieve a happy ending with white wedding and all because they were ''only'' third or second grade cousins, coincidentally the closest blood relation allowed to marry according to actual laws.
** For the most (emphasis there) part in Latin America, people consider cousin relationship to be rather incestuous only if they are first cousins, second cousins and onwards are not subject to this taboo.
* Jonathan and Tammy were a popular couple on ''GuidingLight''. However, the first time they slept together Tammy had no idea they were cousins and Jonathan was using her for revenge on his mother. When she did find out, she was angry at him [[SlapSlapKiss for a long time.]] (About a couple weeks.)
* This is not uncommon in {{Soap Opera}}s in general, given the frequency of "true parentage is revealed" storylines that can make previous non-relatives with crushes on each other into cousins. For example, Cassie [=DiMera=] and Shawn Brady on ''Series/DaysOfOurLives''.
** Then there are people who skirt the edges of this trope by dating their half-siblings' cousins on the other side...
* In the {{HBO}} series ''Series/DreamOn'', Martin and his cousin (played by Helen "Film/{{Supergirl}}" Slater) briefly undergo a bout of frustrated desire for each other, which only dies when they notice, when they finally get the time and privacy to indulge themselves, that their feet are too similar.
* On ''Series/WhatWouldYouDoNickelodeon'', Marc Summers invited a teenage boy and a teenage girl to practice kissing.
-->'''Marc:''' Would you want to kiss her?
-->'''Boy:''' She's my cousin, why?
-->'''Marc:''' She's your cousin!? Are you cousins? I didn't know that! Wow! I have something I want to say but this will put us off the air!
* ''Series/ThirtyRock'' has this when Liz Lemon meets a guy that seems perfect for her. At least, until they go back to his place and she notices a picture of her great aunt. They do the math and figure they are third cousins (i.e. sharing a great-great-grandparent). There's a discussion on how closely related they could be without it being creepy. He says fifth cousins. She says ''never''.
* In season two of ''Series/GameOfThrones'', while Jaime is captured by the Starks, Cersei ends up sleeping with her cousin Lancel because he reminds her of Jaime. Also, like in the books, Tywin Lannister married his cousin Joanna, who died giving birth to Tyrion.
* ''That70sShow'' had an early episode titled "[[ExactlyWhatItSaysOnTheTin Eric's Hot Cousin]]," where said tattle-tale Floridian cousin is [[SheIsAllGrownUp not looking like the last time she visited]]. She blatantly flirts, causing conflicted feelings in Eric. It turns out to be [[WoundedGazelleGambit a trick to get him in trouble]] as revenge for the last time they butted heads.
-->'''Red:''' Eric, do I really have to tell you to stop staring at your cousin?
-->'''Eric:''' ''[snapping out of his MaleGaze]'' What?
-->'''Red:''' Stop staring at your cousin!
* In a ''[[ThirdRockFromTheSun 3rd Rock From The Sun]]'' episode, the aliens went to the family reunion of a family with the last name "Solomon", pretending to be long-lost relatives. Tommy fell in love with his "cousin" and [[HilarityEnsues Hilarity Ensued]].
* Creator/StephenColbert's stalking of his ex-girlfriend Charlene (as in the hit song "[[StalkerWithACrush Charlene (I'm Right Behind You)]]") had been a RunningGag for quite a while before it was revealed that they were also cousins.
** In his book, ''Literture/IAmAmericaAndSoCanYou'', he says that it's okay to marry your cousin because Literature/TheBible doesn't say you can't.
--->'''Colbert:''' Let's see...Leviticus Chapter 18 Verse 12 - ''"Thou shall not uncover the nakedness of thy father's sister"''...blah blah blah ''"thy mother's sister"''...yeech...''"of thy father's brother"''...man, there were some sick Levites...''"of thy daughter-in-law"''...fair enough...''"of thy brother's wife."'' Nope! Nothing about cousins.
* Made mention of at least once in the ''DukesOfHazzard'':
-->'''Bo Duke:''' Daisy Duke, if you wasn't my cousin, I'd marry you!\\
'''Daisy Duke:''' Never stopped anybody in this family before.
* George dated his cousin in an episode of ''{{Seinfeld}}'' in an attempt to get his parents mad after they started neglecting him.
* On ''TheGeorgeLopezShow'', Max gets a major crush on his attractive cousin. George made jokes about their mutant offspring (since Max by himself is already dyslexic) to discourage that. The cousin milks him for all he's worth by having him do all her chores.
* In ''TheBigBangTheory'', Howard, while high from marijuana use (ItMakesSenseInContext), admits he lost his virginity to his cousin at his uncle's funeral. This admission ends up coming back to bite him in the end of the episode in the form of a MundaneGhostStory.
* On the ''GilmoreGirls,'' Lorelai (and later Rory) is horrified to discover that her paternal grandparents were second cousins. Emily doesn't think it's a big deal, since that was common among upper class family in those days.
* ''TheNanny'' had an episode titled "Kissing Cousins" where [[FrenchMaid Fran]] starts to date a Jewish doctor (played by Jon Stewart) who she thinks is perfect for her. They then meet up at a wedding in their temple, where Fran's mom declares, "[[KissingCousins Oh, I see you have met your cousin!]]" This makes them {{squick}} and they stop dating; however it is [[RunningGag mentioned again]] in later episodes.
* In an episode of ''{{Friends}}'', Ross and Monica's female cousin comes to visit for the wedding, and ends up staying at Ross' apartment. After a slo-motion HairFlip, Ross finds he is attracted to her and decides that she is attracted to him too, leading him to try and make a move... HilarityEnsues.
* In one episode of ''Series/HowIMetYourMother'', Ted, Barney and Robin go to a club. Barney grinds on this girl all night before she turns around and he realizes [[spoiler: it's his cousin Leslie.]]
* In ''Series/ChourikiSentaiOhranger'', Kaiser Buldont and Princess Multiwa wed in episode 41 and have a child near the end. It's okay because they're robots.
* In the ''DontTrustTheBInApartment23'' season 2 episode "Original Bitch…", Mark tells June that he left a voicemail on her answering machine. June tells him she didn't get the voicemail because Chloe wouldn't give her the code. The conversation afterwards:
-->'''June:''' She [Chloe] won't tell me anything she cares about!
-->'''Mark:''' She might just a private person. I mean, I was like that when we first met.
-->'''June:''' The first day we worked together, you told me you boned down on your cousin 'cause you didn't want to go to college a virgin.
* ''Series/MarriedWithChildren'': Everyone is family in Wanker County, which came as a surprise to Kelly. Apparently she was a little too "friendly" with one of her relatives; how friendly is unknown, but considering it's Kelly...
* The ''Series/{{Frasier}}'' episode "Beware of Greeks" features a very one-sided version between Niles and Cousin Yvonne, who apparently makes a beeline for him whenever they're at a family gathering.
-->'''Frasier:''' A distant cousin who has a slight crush on Niles.
-->'''Niles:''' "A slight crush?" There are ''cannibals'' who are less man-hungry.
* ''Series/TheTudors'' briefly covers the engagement between MaryTudor and her cousin, Charles V of Spain.

* The second verse of [[Music/WeirdAlYankovic Weird Al's]] AvrilLavigne parody "A Complicated Song" has the protagonist alone with his girlfriend for the first time, presumably about to engage in a little Angry White Boy Polka, when:

-->Her family crest

-->Tattooed on her thigh?
-->And son of a gun

* The eponymous Brenda in "Brenda's Got a Baby" by TupacShakur got involved at the age of 12 with her 20-something cousin and [[TeenPregnancy conceived a child]], and her parents were too wrapped up in themselves and their [[DrugsAreBad drug addictions]] to care. Her boyfriend/cousin leaves her sometime during the pregnancy, and [[FromBadToWorse everything goes to (even further) crap]] [[DownerEnding from there.]] [[spoiler: Brenda is thrown out of the house by her mother shortly after she gives birth, and Brenda is ultimately driven to prostitution to support herself (now probably about 13 or 14) and her baby, and [[DisposableSexWorker eventually killed, presumably by one of her clients.]]]]

* Discussed by EddieIzzard, in regards to the British royal family:
-->[[QueenVicky She]] was one of our more frumpy queens. They're all frumpy, aren't they? Because it's a bad idea when cousins marry! (...) First rule of genetics: spread the genes apart, you know? But the royals are just obsessed with: "Are you a royal family? Are you a royal member? Well, then you can marry me, 'cause you're the same gene pool and our IQ's will go down the toilet." Fantastic. That's why there's no crazy royals, they're all kind of: ''(drawls)'' "Hello, hello. What do you do? Oh, you're a plumber. What on ''earth'' is that?"

* In ''Theatre/{{Antigone}}'', the eponymous character is engaged to her cousin Haemon. Haemon's father Creon and Antigone's mother Jocasta are brother and sister. It's worth mentioning that he is also her first cousin once removed since [[OedipusComplex Antigone's father is a son of Jocasta's]]. Coming from that family, marrying a cousin must've seemed positively conservative.
* At the end of ''TheImportanceOfBeingEarnest'', TheReveal that frees Jack/Ernest to marry Gwendolen also makes them first cousins. This isn't specifically addressed, but he does start referring to her mother as his aunt, so at least they're aware of it.
* In 1879, Cyrano and Roxanne from ''Theatre/CyranoDeBergerac'' are cousins. [[spoiler:Although they don't actually end up together]], their familial connection is never presented as {{squick}}y or an obstacle in their relationship. Given Catholic rules on consanguity this probably means 'cousin' was more a courtesy then genetic relationship.
* Alex and Jenny in ''Theatre/AspectsOfLove''.
* Tybalt in ''RomeoEtJulietteDeLaHaineALamour'' (though not [[Theatre/RomeoAndJuliet the play it's based on]]) ''wishes'' this was the case with him and Juliet.
** In most of the productions anyway. In Hungary it's less "he wishes his cousin returned his romantic love for her" and more "he's so obsessed with her that he thinks ''all'' men, including ''himself'', are unworthy of her". There's still some weirdness going on there, though.
** Toyed with in [[RomeoXJuliet the anime.]] It ''seemed'' that Tybalt would become a RomanticFalseLead for Juliet, but we soon see hat he's got no real romantic interest on her and settles on being her BigBrotherMentor instead. [[spoiler: And AloofBigBrother to Romeo, since in this version he double as Juliet's relative ''and'' as Lord Montague's HeroicBastard. (His mother was a high-ranked Capulet lady, who was seduced by Laertes and later fell victim to DeathByChildbirth)]].
*** And technically speaking, [[spoiler: ''Romeo and Juliet themselves'' are at least distant cousins. Laertes's own father was a Capulet man who abandoned him and his [[SonOfAWhore prostitute mother]], and a good part of Laertes's reason to become a SelfMadeMan ''and'' exterminate the Capulets was revenge against his dad.]]
* In ''Brighton Beach Memoirs'', Eugene has somewhat of a crush on his cousin Nora. However, it's not romantic so much as that he's entering puberty and there's a beautiful girl in the house. His older brother Stanley has a similar attraction to her.
* Subverted in ''August: Osage County''. Ivy is in a relationship with her cousin Little Charles, which is already considered pretty bad by the others. Then [[spoiler: it's revealed that Little Charles is actually the biological son of Beverly, Ivy's father, making the two [[BrotherSisterIncest brother]] [[SurpriseIncest and sister]] as well.]]
* Monty and Phoebe in ''Theatre/AGentlemansGuideToLoveAndMurder''. They're not too closely related though and they didn't meet until they were adults.

[[folder:Video Games]]
* As an extension for its love of the [[BrotherSisterIncest sibling version]] ''Franchise/FireEmblem'' has plenty of this, several preexisting relationships in 4s 2nd generation take on this form, and by selective pairing of characters in the first generation it is possible to make a vast number of such pairings.
** Two particularly noteworthy incidents in [=FE4=]'s second generation are the predestined couples of Lana/Faval and Lester/Patty. Because their mothers Aideen and Briggid were identical twins, IS pulled off the impressive feat of doing this and BrotherSisterIncest at the same time.
** It is possible to make Roy and Lilina from the 6th game cousins... [[spoiler:by pairing Eliwood with the Pegasus Knight Fiora and Hector with either of Fiora's youngest sisters Florina or Farina]] in the 7th game (which is a prequel to 6). Since 7 was not released yet (and the pairings involved exist among other possible pairings), the 6th game never makes any mention of the possibility.
** ''VideoGame/FireEmblemAwakening'' uses a love system very similar to that of the fourth game. Either Lucina or a Chrom-fathered Cynthia or Kjelle can potentially marry their paternal cross cousin Owain while other cousin pairings can be set up with certain combinations of parents. The international release has the status screens of such a pairing {{Bowdlerize}}d to read "Companion" instead of husband/wife, though. A female Morgan mothered by Lissa can also marry her cousin Inigo or Brady.
* An ill-fated romance between two KissingCousins forms part of the plot of the adventure game ''The Dark Eye''.
* Though nothing ever comes of it, Brother in ''VideoGame/FinalFantasyX2'' has a noticeable (and one-sided) crush on Yuna. Brother's father and Yuna's mother were siblings.
* It should be noted that in ''TheSims2'' and ''TheSims3'', the game does not even allow the option for first cousins to be married. (A certain cheat will allow them to have offspring, if the player so chooses). However, more distantly related Sims have the ability to seek romantic interactions with one another (probably because the family tree in the game does not recognize first cousins once removed and beyond, or great-grandparents for that matter).
* At the end of ''VideoGame/{{Persona 4}}'', your little cousin Nanako tells you that she wants to marry you when she grows up, and apparently won't take "no" for an answer. If you didn't max the link, her father won't allow it. If you did, he's gonna hold you to it.
* In ''VideoGame/{{Bully}}'', the Preppies are the kids of a bunch of inbred rich people. When [[SmugSnake Gary]] gets them to attack you with his old trick of insulting them and saying you did it, the "inbred" insult is met with indignation and the phrase "And first cousins is legal anyway!"
* In ''JadeEmpire'', it's revealed that [[spoiler:Dawn Star is the long lost daughter of Sun Li, the brother of the Emperor.]] As a result, when a male protagonist [[spoiler:forms a ménage à trois with the Princess Silk Fox and Dawn Star, the two ladies are in this kind of relationship.]]
* In ''MatchesAndMatrimony'', this is one of the nine paths which the player character can take, if she accepts (or is too weak-willed to refuse) the proposal of her cousin Mr. Collins.
* BlazBlue: While there are no examples given, the Yayoi family (Tsubaki's family) practices this; they are so obsessed with blood purity that marrying in the family is ''the only choice they get''. Which has led to the family being RoyallyScrewedUp; Tsu's the only surviving heir to the family

[[folder:Visual Novels]]
* A lot of visual novels will often feature a cousin as an option. Whether or not the main character ends up in a relationship with her (or him) depends on the player's choices.
* Nayuki from ''VisualNovel/{{Kanon}}''.
* Elise from ''{{Canvas 2}}''.
* Sakura from ''DaCapo''.
* Sayaka from ''VideoGame/YoakeMaeYoriRuriiroNa'', although the protagonist treats her like and refers to her as his sister.
* Miyuki Takamachi of ''TriangleHeart3SweetSongsForever''. Both her status as Kyouya's cousin and potential love interest [[AlternateContinuity may or may not still be present in]] ''MagicalGirlLyricalNanoha'', as one shot in the first season showed signs of her getting jealous when she heard that Kyouya was going to visit [[OfficialCouple his girlfriend, Shinobu]].
* While he's joking for the most part, ''VisualNovel/UminekoWhenTheyCry'''s Battler Ushiromiya is not adverse to playing grab-ass with his first cousin Jessica. As for more serious cousin-cousin relationships, the second half of the story reveals that [[spoiler:Sayo Yasuda (who is implied and later confirmed to be Shannon, Kanon, ''and'' Beatrice) is involved with as many as ''three'' of [[AmbiguousGender his/her]] cousins. Who are also his/her niece/nephews (since Kinzō is both Sayo's father ''[[ParentalIncest and]]'' [[ChildByRape grandfather]]). As it turns out, this is a large part of Sayo's issues, since finding out that s/he's actually related to his/her love interests makes him/her think of him/herself as disgusting and no better than Kinzo]].
* The entire Nanaya clan from ''VisualNovel/{{Tsukihime}}'', with the exception of Shiki due to his situation. They only breed within the clan to sustain and increase the psychic power within their bloodline.
* One of the routes in the VisualNovel ''AoiShiro'' pairs the main character up with her cousin Kaya.
** [[NinjaPirateZombieRobot Demon Vampire Lesbian Kissing Cousins?]]
* Saki from ''VisualNovel/{{Snow Sakura}}''.
* ''Sono Hanabira Ni Kuchizuke Wo'': Sara and Kaede; they (at time of writing) supply the Trope Image for YuriGenre.

[[folder:Web Comics]]
* Calvin of ''Charlie Horse'' provides a [[http://www.krakow.krakowstudios.com/archive.php?date=20090224 handy chart]].
* Referred to in ''Dead Days''. Brown-hair claimed he knew everything, so Blondie tested him out. Brown then stated Blondie's first kiss was with a cousin at a family reunion. His name was Steve.
* Tedd of ''Webcomic/ElGoonishShive'' averts this trope, being almost allergic to the idea of his "ugly cousin" [[spoiler:Nanase]] as a sexual being ''at all''. (Said cousin is, of course, scorchingly hot actually, as Tedd admits much later.)
* Rudy and Fiona in ''Webcomic/KevinAndKell'' are technically first cousins, but only by marriage ([[EveryoneIsRelated two marriages actually]]) so it's okay.
* The webcomic ''Lines and Stripes'' has a couple like this, but the objection of people isn't so much that they're cousins, but that they're double cousins. [[http://en.wikipedia.org/wiki/Double_cousin The other wiki has an explanation as to why this is a bad idea.]]
* In ''TemplarArizona,'' Mose's grandfather want him to "keep the bloodline pure" and tries to browbeat him into taking up with the temple dancers. Mose objects on the grounds that they're his cousins ... and underage.
* ''Webcomic/TriggerStar'': Saeurkraut and Avacado's idol, Exlax The Mighty. Not only are they cousins, they were lovers.
* In ''Webcomic/ScandinaviaAndTheWorld'', Norway and his cousin, Jan Mayen, actually get in trouble for being in a relationship, resulting in the latter's execution.
* ''Webcomic/SandraOnTheRocks'': Eloise has a romantic thing for her cousin -- perfectly legal in France, where they live, but [[http://www.sandraontherocks.com/strips-sotr/poison_apples close enough to make her uncomfortable about declaring it.]] On the other hand, when Nadine teases her about the subject, it gives her an excuse to declare that [[ForbiddenFruit "FORBIDDEN LOVE IS HOT!!!"]]

[[folder:Web Original]]
* ''{{HomeSchooled}}'': Juan the gardener has an infatuation with Dulce the housekeeper, despite the fact that they're 2nd cousins. This disgusts her to no end.

[[folder:Western Animation]]
* In ''WesternAnimation/MonsterBusterClub'', [[spoiler: Cathy's big secret is that she kissed her cousin Elton, but only on the cheek, and only on a dare.]]
* ''WesternAnimation/WolverineAndTheXMen'' made Silver Samurai and Mariko Yashida into husband and wife, even though they're cousins in the comics. It's not mentioned one way or another if they're still related in the cartoon. [[JustifiedTrope Justified]] as they're Japanese and it fits their culture.
* Apparently the motivation for the founding of Shelbyville in ''TheSimpsons'' was a disagreement between Jebediah Springfield and Shelbyville Manhattan over whether to legalize cousin marriage. At one point Bart escapes a bunch of Shelbyville kids by [[LookOverThere pointing and shouting "Look! Somebody's attractive cousin!"]]
* In the Swedish/British cartoon ''WesternAnimation/TheThreeFriendsAndJerry'' all the main characters are after blonde, very developed Linda, even her cousin Frank. ''Especially'' her cousin Frank.
* Invoked in an episode of ''TotallySpies''. When looking up her relatives in France, Alex wonders what her cousins look like and pictures a [[{{Bishounen}} handsome guy]] with BishieSparkle.
* When Hervé and Nicolas follow the gang to the factory in an episode of ''WesternAnimation/CodeLyoko'', Odd and Aelita pretend to have sneaked out of school on a date, despite the fact that Aelita joined the school under the pretense of being Odd's first cousin. Note that it works as a perfect in-universe FridgeBrilliance: it was FakeOutMakeOut, but Hervé and Nicolas probably reads it: "They are kissing? But... They are cousins! Oh... No wonder they are hiding." Notably, when Hervé report the fact to Sissi, she obviously doesn't believe him and finds the concept absurd.
* ''ScoobyDoo'' and one of his cousins were attracted to one of their cousins, Scooby-Dee. It's less {{Squick}}y since they're dogs, and inbreeding is typical.
* On ''WesternAnimation/TheAngryBeavers'', the episode "Stump's Family Reunion" has Dagget trying to help [[CompanionCube Stump]] hook up with his distant cousin [[MeaningfulName Vanity]].
* On ''KingOfTheHill,'' Bill goes back to his ancestral home and meets three beautiful women named [[FloralThemeNaming Lily, Rose and Violetta]]. All three come onto him, but Bill knows that one of them is his biological cousin while the others are his cousins' widows; he just doesn't know which is which. The three all sneak into his room at night and wind up in a cat-fight before Bill's other cousin (an [[AmbiguouslyGay almost-certainly-gay]] male) tells Bill it's Violetta he's related to. [[HollywoodDateless Bill winds up sleeping with both Lily and Rose]].
* On ''WesternAnimation/OggyAndTheCockroaches'', Jack, Oggy's cousin, is attracted (and has the feeling reciprocated) to Monica, Oggy's twin sister. One episode has them married with an infant daughter.
