[[caption-width-right:350: Well, they do [[HappilyMarried look happy...]]]]

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

Also known as cousincest, romantic/sexual relationships between cousins (meaning, generally, ''first'' cousins) are a phenomenon that has been more accepted in some cultures and eras than others. 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, [[ValuesDissonance 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 [[{{Appalachia}} the Appalachian Mountains]]) are often the [[AcceptableTargets preferred butt of many bad jokes]] as well as occasional bits of SelfDeprecation 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. All states permit marriages between second and third cousins, but even these are looked at funny. In the UK first cousin marriage is unusual and would be regarded as rather odd, but not with the same severity as the US. Second cousin marriages and beyond would be seen as unremarkable.

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 meaning has long since fallen by the wayside.

[[folder:Anime & Manga]]
* 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 ''Manga/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.
* ''Manga/{{Naruto}}'':
** In the 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 ''Theatre/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 share 25% of their genes, as opposed to the 12.5% that 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 chapter 20, where Neji gets a severe nosebleed when he hears about Hinata's breasts getting even bigger than they already were.
*** Lee's comments about how freakishly similar all the Hyuugas look to each other, even by family standards, might also be hinting at just how close the Hyuugas are.
*** 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''.
*** In {{canon}}, Neji remarked to his father that Hinata was beautiful when they first met. When [[PuppyLove he was 4 and she was 3]].
** [[StalkerWithACrush Karin]] showed some interest in [[spoiler:Naruto]] at one point. Consider the fact that [[spoiler:they're ''both'' from the [[TheClan Uzumaki clan]]]]. Her attraction to Sasuke is also this to a lesser degree, since [[spoiler: the Uzumaki and Uchiha are genetically related, however distantly.]]
** The First Hokage, Hashirama Senju might do this when he married Mito Uzumaki, as the Uzumaki are an offshoot of the Senju. Such practice is not unusual; the two clans tend to trade marriage partners to maintain their ancestral connection. On top of that, the arrangement allowed Hashirama to keep an eye on Kurama, who was sealed within Mito. However, their exact relatedness is not stated.
** Then, of course, the final arc reveals that [[spoiler: the Hyuga are related to the Senju, Uzumaki, and Uchiha. Naruto ends up marrying Hinata, the Hyuga princess par excellence.]] Though since their (known) most recent common ancestor lived hundreds of years ago, it doesn't pose much problem.
* Hanamori Pink did a short story called ''Cherry ♥ Blossom'' where the main couple are 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''.
* Mori and Honey from ''Manga/OuranHighSchoolHostClub'' are first cousins, and [[ShipTease quite close]]. It's probably just a case of TrueCompanions, but Mori's bodyguard/protector-like relationship to Honey sure pleases the YaoiFangirls both InUniverse and out. Renge tries to encourage them to play it up a few times.
* 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]]. But they didn't remove the subtext successfully, [[DubText rendering them lesbian kissing cousins]].
* When Creator/{{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. [[spoiler: Tomoyo's crush on Sakura turns out to be this when it's revealed that they're second cousins. In a case of GenerationXerox, her mother also had a crush on Sakura's mother.]]
* In ''Literature/HalfPrince'', Rose kisses [[AttractiveBentGender Prince]] in [[MassivelyMultiplayerOnlineRolePlayingGame the game]]. Eventually, it's revealed that Rose's player is actually her cousin. And by cousin, it's meant that 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 ''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 it's not known if Kaguya knows ''that''.]]
* ''Manga/DetectiveConan'':
** In one of the earlier cases, the killer's motive for killing his grandfather, etc. was because he fell in love with his cousin, and the older man forbid them from marrying. The killer's parents were also cousins, and the patriarch reluctantly agreed to their marriage.
** The series already hinted that [[spoiler:Mary Sera]] may or may not be [[spoiler:Elena Miyano]]'s sister, but WordOfGod stated during an interview in Singapore that [[spoiler:Shuuichi Akai and Akemi Miyano]] were indeed cousins. Whether they were aware of that fact isn't clear, but they were dating before the latter died.
* Suzuho in ''LightNovel/MagiciansAcademy'' is Takuto's cousin, and naturally one of the haremettes fighting for his affection.
* In ''Anime/SuperDimensionFortressMacross''/''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/PleaseTwins'' 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 [[PrecociousCrush several years younger than her]], so it's unrequited.
* Sachiko Ogasawara in ''LightNovel/MariaSamaGaMiteru'' is intending to marry her cousin Suguru after she graduates. It's an ArrangedMarriage, [[spoiler:and he's [[IncompatibleOrientation gay]]]], but Sachiko has stated she has had feelings for him in the past.
* In a filler episode of ''Manga/ShugoChara'', Amu admits that her cousin Shuu was her first real crush.
* In the manga of ''LightNovel/TheFamiliarOfZero'' 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 true examples.
* The protagonist and his second-cousin in ''Hanayashiki no Juunintachi''.
* In ''Manga/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'': Austria is the cousin of Germany and Prussia, and he gets a ''lot'' of HomoeroticSubtext with them, though the OfficialCouple is Austria/Hungary. He allows Germany to practice sexual activities with him, to prepare Germany for Italy.
* ''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]].
* ''LightNovel/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, and have TheBigDamnKiss and one point.
* In ''Manga/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]].
* In ''Manga/TheWorldIsStillBeautiful'', Kitra has feelings for his cousin Nike, but she only seems to him as a good childhood friend.
* ''Manga/SandChronicles'''s Fuji at one point dates his cousin Mariko, who takes care of him after moving to Tokyo. [[spoiler:They eventually marry, but it takes a long time to gain his parents' approval]].
* In ''Manga/TokyoGhoul [=:Re=]'', Kanae von Rosewald is obsessively in love with his cousin, Shuu Tsukiyama. While their family has a long history of RoyalInbreeding, Shuu seems oblivious to Kanae's feelings. This leads to Kanae becoming a CrazyJealousGuy, repeatedly attempting to murder Kaneki out of jealousy.
* Makoto and Erio from ''LightNovel/GroundControlToPsychoelectricGirl'' have plenty of ShipTease. It helps that Makoto didn't even know Erio existed until he was sixteen. Makoto also shows attraction to his aunt.
* ''King's Game: Origin'' mentions that cousins Kazunari and Natsuko are in love. In contrast to most examples, they get scorn for their relationship. It's mentioned that cousin incest was legal but socially unacceptable in 1970s Japan.
* ''LightNovel/ACertainMagicalIndex'': In her brief appearance, Touma Kamijou's cousin Otohime Tatsugami tries to hit on him.
* ''Manga/RosarioToVampire'': Tsukune Aono's cousin Kyouko becomes attracted to him when she sees how tough he has become.

* Discussed by Creator/EddieIzzard, in regards to the British royal family:
-->'''Eddie:''' [[UsefulNotes/QueenVictoria 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?"
* Among Creator/JeffFoxworthy's indications that "You Might Be a Redneck..."
-->"If your family tree never forks..."\\
"If you go to family reunions hoping to pick up girls..."

[[folder:Comic Books]]
* In the German comic ''Wendy'', [[TheProtagonist Wendy]] dates her foster-[[KissingCousins cousin]] for most of the story until her aunt decides that she doesn't want to adopt him and his twin sister after all, as they aren't as rich anymore. After that, he breaks up with Wendy to date his previous foster [[NotBloodSiblings sister]] Vanessa instead, while implied to still live in her house. It's [[UnderStatement weird]].
* Creator/{{Marvel|Comics}} superhero Black Bolt, the king of ComicBook/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.
* Creator/MarkMillar's post-apocalyptic ''ComicBook/{{Wolverine}}'' story "ComicBook/OldManLogan" features a future were [[ComicBook/IncredibleHulk Hulk]] and cousin ComicBook/SheHulk 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 doesn't help... It's not the first time the romantic/sexuality thing has been brought up between these two as some of Fixit's dialogue with her implies he's more than game. There's also some implication that it may not be consensual.
* Franchise/{{Superman}}:
** His future daughter engages in [[http://25.media.tumblr.com/tumblr_lre8o6TFW51qkwdf0o1_400.jpg a literal example]] in a [[UsefulNotes/TheSilverAgeOfComicBooks Silver Age]] {{Elseworld}} story taking place in the future. (For those who don't know the Franchise/{{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]] (Comicbook/{{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 ComicBook/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 [[UsefulNotes/TheSilverAgeOfComicBooks Silver Age]] story ''Action Comics #260'', Clark has Kara disguise herself as a superheroine from another dimension, and she and Supes proceed to have make-outs (in ''front'' of Lois), all to fool some dim alien invasion. She was explicitly underage at the time, too. Yeesh.
** And from Bronze Age storyline ''Comicbook/KryptonNoMore'' comes [[https://lh4.googleusercontent.com/-42hj4CP59UU/TW0EOjbIjyI/AAAAAAAALSk/MyJ0VPlDuGo/s1600/sm+309-04.jpg Superman walking out of the shower and finding his cousin waiting for him]]... and the writer seems completely unaware of the tone he is setting. At least Kara was already an adult woman at the time.
** In ''ComicBook/{{Supergirl}}: Candor'', Kara is mind-controlled by evil telepath Saturn Queen into getting engaged to Ultraman, an evil AlternateUniverse counterpart of Superman, but genetically it makes no difference.
* The ultimate desire of Creator/MarvelComics superhero [[ComicBook/AgentsOfAtlas Namora]] has been shown to be her cousin [[Comicbook/SubMariner Namor]]. Namor's late wife Dorma was also his cousin. And 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 he was freaky with his "finger-skateboards", but as he said, at least he got to "make oot" that summer.
* In the Comicbook/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 and even being a fighter pilot like her--she warms up to him. It's never shown whether they actually get married at some point. And their being cousins never seemed to bother Plourr, it was only the "arranged marriage to an aristocrat she hadn't seen in 20 years" part that was a problem.
* 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 ''ComicBook/ArchieComicsSonicTheHedgehog'', 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:Comic Strips]]
* Norman ''Drabble'' once ran into his girlfriend at a family wedding. After spending some time having fun with her, he asks why she's there. It turns out they're both related to the bride. A few strips later, it was revealed that they weren't blood relatives, but Norman didn't tell his girlfriend that immediately.

[[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]]''. Also, Belle-Etoile and her husband Cheri are double first cousins--their fathers are brothers and their mothers are sisters.
* Also occasionally featured in the fairy tales of Henriette-Julie de Murat and Charlotte-Rose de Caumont La Force.
** In Murat's fairy tale ''Perfect Love'', the main couple, Irolite and Parcin Parcinet, are first cousins. The two have another cousin, Azire, who is in love with Parcin Parcinet.
** Another Murat fairy tale, ''The Palace of Revenge'', features first cousins Imis and Philax in love. Subverted, however, in that the two do not get married at the end.
** La Force's ''The Good Woman'' features two cousin couples. The main couple, Lirette and Finfin, are first cousins. The BetaCouple, Mirtis (Lirette's older sister) and Finfin's unnamed younger brother, are also first cousins.
* 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.
* ''[[http://www.mythfolklore.net/andrewlang/359.htm Rosanella]]'' features a second cousin couple. Rosanella's father and Mirliflor's father are first cousins.
* ''[[http://www.mythfolklore.net/andrewlang/379.htm Prince Vivien and the Princess Placida]]'' has the titular Vivien and Placida, who are first cousins. Placida is the daughter of King Gridelin and Queen Santorina, while Vivien is the king's nephew.
* Also featured in the Breton fairy tale ''[[http://www.mythfolklore.net/andrewlang/159.htm The Groac'h of the Isle of Lok]]''. The protagonists, Houarn Pogamm and Bellah Postik, are first cousins through their mothers.
* ''Ourson'' by the Comtesse de Segur: the protagonist Ourson and his love interest Violette are first cousins.
* The now-forgotten French fairy tale novella ''The Tyranny of the Fairies Destroyed'' by Madame d'Auneuil features several couples. The main couple, Philonice and Anaxandre, are first cousins.
* In the Arabian Nights story ''[[http://www.mythfolklore.net/andrewlang/292.htm The Story of Prince Ahmed and the Fairy Paribanou]]'', the sultan's sons compete for the hand of their first cousin, Princess Nouronnihar. Ali, the middle son, ends up marrying her. [[AvertedTrope Averted]] with the protagonist Ahmed (the sultan's youngest son) and his wife Paribanou, who are not relatives.
* 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:Fan Works]]
* 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 UsefulNotes/ImperialJapan. The Crown Princess, Pupa, is already set to marry her first cousin, Prince Morphin.
* There's a fairly large following in the ''WesternAnimation/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 frequent 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 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.
* The ''Disney/{{Frozen}}'' fanfic ''[[Fanfic/BecomingFree Becoming Family]]'' has a romance developing between Elsa's daughter Katja and Anna's son Matteus. In their case, Katja is adopted so they're [[NotBloodSiblings unrelated by blood]].
* In ''Series/GameOfThrones'', cousin marriages are more commonplace among nobility in Westeros for political reasons. For example, in the show itself, Tywin and Joanna Lannister were first cousins and Ned Stark's parents were first cousins once removed. Among the fandom, there are fans who want Jon Snow and Sansa Stark to become an item and produce fanworks shipping them (known as the Jonsa ship for Jon/Sansa). Though Jon and Sansa believe they are half-siblings with the same father (Ned Stark), the Season 6 finale revealed to the viewers (and Bran Stark) that a long-believed fan theory of Jon's parentage is true: [[spoiler:Jon is the son of Ned's sister Lyanna Stark and Rhaegar Targaryen, making Jon and Sansa cousins. Ned Stark claims and raises Jon as his illegitimate son alongside his kids with Catelyn to protect Jon from Robert Baratheon, who wanted to kill anyone with Targaryen blood]].
* The pairing of Little Foot and Ali is surprisingly popular from the ''WesternAnimation/LandBeforeTime'' series in fanwork. However, Little Foot's grandpa clearly states that Ali's heard are Little Foot's family's cousins.
* ''FanFic/DancingWithMyPunchlines'' has Maedhros and Fingon (who are step-cousins but nonetheless), and [[spoiler: Finrod and Curufin, and Finrod and Caranthir]]
* ''Franchise/{{Superman}}'' story ''Fanfic/SupermanOf2499TheGreatConfrontation'' provides some examples:
** [[Franchise/{{Superman}} Alan]] and [[ComicBook/{{Supergirl}} Kath]] are twenty-second cousins, so no one objects to their relationship.
** On the other hand, Adam and Sybilla are first cousins. Neither of their parents is comfortable with their getting together.
* In ''Series/{{Smallville}}'' fanfic ''[[https://archiveofourown.org/works/848400/chapters/1621084 Under the Influence]]'', exposure to Red Kryptonite leads first cousins Clark and Kara to spend the night together.
* In ''[[https://www.fanfiction.net/s/12745758/7/No-longer-alone No longer alone]]'' Narcissa mentions having sex with Sirius because she didn't want her first time to be with Lucius Malfoy.
* In ''Fanfic/TheBerserkersBride'', Hiccup and Snotlout were originally meant to marry (Snotlout thinking that she was useless while she thought of him as TheBully), only for her to instead marry Dagur to unite their tribes. After she visits Berk with Dagur and reveals that she is pregnant, Snotlout tries coming on to her (thinking that she's now attractive) and even almost tries raping her.

[[folder:Films -- Animation]]
* ''Franchise/TheLionKing'':
** 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.
** [[Disney/TheLionKingIISimbasPride 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.
* In ''Disney/{{Bambi}}'', Faline is referred to as Bambi's cousin in some supplementary material. In the [[Literature/{{Bambi}} book]] they are first cousins through their mother's. Disney made sure to not mention this in the film, making it vague if they're related or not.

[[folder:Films -- Live-Action]]
* ''Film/{{Dames}}'': Lovers Jimmy and Barbara are members of the same extended family. "It doesn't seem right loving each other the way we do, being related," says Barbara, only for Jimmy to parry that they're "13th cousins."
* ''The Secret Garden'':
** In [[Film/TheSecretGarden1993 the 1993 film]], Colin 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. 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. However, in this version, they are not related -- Colin's father is an old friend of Mary's parents instead of being Mary's uncle.
* In ''Film/TheGodfatherPartIII'', Micheal's daughter, Mary, and his nephew, Vincent, are in love. Michael is against their relationship, but Mary's mother, Kay, is not. However, Michael's objections are apparently not based on consanguinity, but the danger of Vincent's lifestyle.
* In the Victorian farce ''Film/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 this (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.
* 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 UsefulNotes/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]].
* 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 was a maternal half-sibling (uterine) and the other was 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.
* In ''Film/TheWolfOfWallStreet'' to establish what a {{Cloudcuckoolander}} Donnie Azoff is, after Jordan Belfort and Azoff form a business partnership Belfort asks him if the rumors that he married his cousin are true. Azoff says they are (as noted in the Quotes page of this trope), and when Belfort asks about the risk of their kids having a disability, Azoff says they would drop them off at an institution to deal with kids like that.
* Averted in ''Film/OnceUponATimeInChina'' where Wong Fei Hung and his Aunt 13 are ''not'' blood relatives, though he calls her aunt even when they are around the same age because their fathers are sworn brothers.
* In the Saiorse Ronan movie ''Film/HowILiveNow'', protagonist Daisy quickly falls in love with her cousin Edmond (they're first cousins, her dad is the brother of Edmond's mother) and the feeling is mutual. So much so that they eventually move beyond the kissing stage.
* ''Film/{{Clerks}}'': Jay says he'll have sex with AnythingThatMoves -- including his own cousin, possibly.

* German novel ''Literature/TheTinDrum'' has Agnes and Jan Bronski. It is left to speculation on whether main character Oskar is Jan's son or that of Agnes's husband Alfred. [[spoiler: Agnes's second child is definitely from Jan and she kills herself because of realizing that]].
* Multiple books by Creator/JaneAusten have examples of this.
** In ''Literature/MansfieldPark'', the main character, Fanny Price, and her first cousin Edmund Bertram. (The elder Mr. Bertram was concerned about adopting Fanny for this very reason.)
** Anne Elliot in ''Literature/{{Persuasion}}'' is wooed by her cousin (and her older sister wants to marry that same cousin). It's implied that he's actually a few branches away on their family tree, but he still flirts with Anne by saying he hopes her name never changes.
** In ''Literature/SenseAndSensibility'', Colonel Brandon's first love was his cousin Eliza Williams. They eloped, but his father stopped them and forced Eliza to marry Colonel Brandon's older brother. In the present, Eliza's namesake daughter (and Brandon's ward) is commonly believed to be Brandon's natural daughter.
** ''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 of them.
*** Lady Catherine de Bourgh wants her nephew to marry her daughter.
* ''Literature/TheCampHalfBloodSeries'' and its associated [[Literature/TheKaneChronicles spin-off]] [[Literature/MagnusChaseAndTheGodsOfAsgard series]]:
** Some couples in the franchise, particularly from the Greco-Roman series, are technically this, as their divine parents are part of a really complicated TangledFamilyTree. For example, the main couple, Percy and Annabeth, are first cousins once removed, since the former's father, Poseidon, is an uncle of the latter's mother, Athena. However, ''Literature/TheHeroesOfOlympus'' handwaves this by stating that gods don't have DNA, so it isn't creepy for couples with different divine parents to have a relationship. Couples with the same godly parents, however, ''is'' creepy.
** Other than gods, the ''Literature/MagnusChaseAndTheGodsOfAsgard'' series has Sam being betrothed to Amir, who is explicitly stated to be a relative. They are both descended from the RealLife 10th-century traveler Ahmad ibn Fadlan, but whether there are closer shared ancestors is unknown. Cousin marriage (or at least marriage between close families) is actually a common practice in the Arab world, not only to strengthen alliances (the Arabs being traditionally a [[TheClan clannish]] society) but also to keep inheritance in-family.
* 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 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. It is claimed Numenorean laws prohibited any marriage closer then second cousins.
** Invoked with Maedhros and Fingon. To complicate things, they both were males -- and their fathers were not unlike CainAndAbel.
** 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). They start off a ChildhoodFriends, but come mating season as adults and Bambi becomes deeply attracted to his female cousin. They end up having twin foals together, but by their birth [[spoiler:Bambi has already [[DisappearedDad abandoned them]]]].
* 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]].
* Creator/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.
* ''Literature/TheBible'':
** 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, because 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 degree. 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. Essentially if a pure or half-blood wizard marries someone who isn't Muggle-born, they're going to be related in some way -- however distantly.
** 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 were strongly implied to be third cousins. The Black Family Tree includes as Dorea Black's husband Charlus Potter, whose information fit with him being James Potter's father, although this was jossed by the revelation in Pottermore of James's father as Fleamont Potter, whose exact relationship to Charlus remains unknown to date.
** 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, and a streak of mental instability, such as with Morfin Gaunt. Although in this case, it's quite strongly implied that the Gaunts have gone [[BrotherSisterIncest much]] [[ParentalIncest further]] than this trope to keep the bloodline "pure".
* The corrupt churchman Annias tries to persuade Queen Ehlana to marry her cousin, Prince Lycheas, in the Creator/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 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 ''Literature/TheEnchantmentEmporium'' 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.
* 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 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.
* 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 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.
* 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 ''Literature/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.
* Being set in a MedievalEuropeanFantasy world, this is prevalent in ''Literature/ASongOfIceAndFire''. The most prominent example is [[MagnificentBastard Tywin Lannister]], who married his cousin Joanna, and there are several other minor examples mentioned.
** Tywin and Joanna's daughter Cersei is also sleeping with her cousin Lancel (her cousin on Twyin's side, if you're curious). It becomes a plot point, thanks to how sensitive that information is--though not because he's her cousin, but because she's the king's widow, and how jealous her {{twincest}}uous brother is. Yeah, it kinda runs in their family…
** Ned Stark's parents Rickard and Lyarra were first cousins once removed, Lyarra being the daughter of Rickard's grandfather's brother.
** The Targaryens, due to their obsession with blood purity, would marry their parent's siblings or cousins if they did not have a sibling to marry. Viserys I married an Arryn cousin, who the current generation of Targaryens are descended from. Around the Dance of the Dragons, the Targaryen intermarriages with each other and their relatives the Velaryons makes for a very TangledFamilyTree (though maybe less inbred considering Rhaenyra's "Velaryon" children were more likely the result of an affair, though they all died without issue).
** Also, due to the fact that the Baratheons are descended from Aegon the Conqueror's bastard half-brother, the bride and groom in any Targaryen-Baratheon marriage will at the very least be distant cousins (one case was actually an aunt-nephew marriage, since the groom's grandmother remarried to a Baratheon and had a daughter). The same is true for any marriage between the Targaryens and Martells after the reign of Daeron II, due to Daeron marrying the Prince of Dorne's sister, while his sister married the Prince.
** Lord Wyman Manderly at one point suggests him or his second son Ser Wylis marrying his cousin Lady Donella Hornwood, hoping to get her lands.
* 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 (her sisters do concede that Cullen would otherwise be a good husband).
** [[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-UsefulNotes/WorldWarII 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 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 Creator/DorothyLSayers's ''Busman's Honeymoon'', Literature/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.
* Anne de Bourgh and Colonel Fitzwilliam in the ''Literature/MrAndMrsDarcyMysteries''.
* In Jorge Isaacs's ''María'', the titular María is courted by her second cousin and narrator of the story, Efraín. The family doesn't necessarily approve, but it's less for their blood relation and more because Efraín is about to go study abroads ''and'' [[spoiler: María is an IllGirl who will not live for too long.]] [[spoiler: It ends in tears when Efraín goes to study in London and María dies of her illness when he's still there.]]
* Creator/AgathaChristie's Literature/TommyAndTuppence book, ''The Secret Adversary'', features Julius Hersheimmer, a millionaire looking for his missing cousin Jane Finn. While he's never met her since his father disowned his sister (Julius' aunt and Jane's mother), he has her picture and falls in love with her. [[spoiler:By the end of the book, Jane has been rescued and fallen for Julius in turn.]]
* ''Literature/TheKharkanasTrilogy'':
** [[TheAlcoholic Hunn Raal's]] three cousins Serap, Risp and Sevegg seem devoted to him, and rumor has it that's because their loyalties are forged beneath the furs. They're second cousins, so it's legal, but still raises eyebrows.
** Averted with Faror Hend and Spinnock Durav. They're first cousins, and Faror Hend's attraction to Spinnock is so obvious even her commander has to tell her to restrain herself, while Spinnock is completely clueless.
* In ''Literature/HopeLeslie'', there's William and Alice and, years later, Hope and Everell, but in both cases they are distant cousins.
* In ''Literature/TheDinosaurLords'', lovers Jaume and Melodía are first cousins, and no-one bats an eye at their romance, even pushing them towards engagement. Deliberate, as the story takes place in equivalent of fourteenth-century Europe.
* Averted in ''Literature/TheGoblinEmperor'': Maia, the new emperor, does not know much about the noble families, but when his marriage is discussed he draws attention to the fact that some of the potential brides must be related to him, and says that he would rather not marry a cousin. His secretary promptly excludes any woman closer than the third degree of kinship from the list.
* In ''Literature/WarriorCats'', seeing as they're semi-realistic cats, and they live in Clans that don't allow intermixing, this is kind of inevitable, and there are several such relationships like this.
* According to [[Literature/{{Deryni}} King Kelson]] getting a dispensation to marry a first cousin once removed isn't a problem, implying that the Church would be reluctant to allow marriage between a couple more closely related.
* In Creator/JohnCWright's ''[[Literature/MothAndCobweb Green Knight's Squire]]'', when it comes up that Nerea is Gil's cousin, Ruff is quick to point out that means second cousin once removed.
* Wang Yuyan's one-sided crush on Murong Fu in ''Literature/DemiGodsAndSemiDevils''.
* In ''Literature/ATangledWeb'' by Creator/LMMontgomery, the Dark and Penhallow families have intermarried almost exclusively, to the point that during the time period the book takes place, pretty much all the marriages and relationships shown are between cousins.
* In ''Literature/BrightLines'' Ella is attracted to her female cousin Charu. It's even more complicated becuse Ella was orphaned as a child and raised as Charu's sister.

[[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 hasn't 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 ''Film/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, unbeknownst to him, [[spoiler: suffered from mental retardation as a result 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 a white wedding and all because they were ''only'' third or second 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 relationships to be too incestuous only if they are first cousins; second cousins and onwards are not subject to this taboo.
* 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...
* Jonathan and Tammy were a popular couple on ''Series/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.)
* In the Creator/{{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''.
* ''Series/GameOfThrones'':
** In Season 2, while Jaime is captured by the Starks, Cersei ends up sleeping with her cousin Lancel because, according to the books, he physically resembles a young Jaime. While cousin relationships are not uncommon in Westeros, this establishes Cersei's disturbing habit of shaking the family tree for a bed partner.
** Also, like in the books, Tywin Lannister married his cousin Joanna, who died giving birth to Tyrion. The practical result is that her surname was already "Lannister" even before she married Tywin. In part, this also informs how much of a hypocrite Tywin is. He plans to force all three of his children to marry against their will to secure political alliances, demanding that they put the good of the family above their own personal happiness. Problem is, Tywin ''himself'' married for love — marrying a first cousin meant he didn't secure a marriage alliance with another powerful Great House.
** Sansa's maternal aunt, Lysa Arryn tells her right after accusing her of sleeping with Littlefinger, that she can marry her son, Robin.
* ''Series/That70sShow'' had an early episode titled [[ExactlyWhatItSaysOnTheTin "Eric's Hot Cousin"]], where said tattle-tale Floridian cousin does [[SheIsAllGrownUp not look 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 {{male gaze}}]'' What?\\
'''Red:''' Stop staring at your cousin!
* In a ''Series/ThirdRockFromTheSun'' 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 {{Hilarity Ensue|s}}d.
* 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, ''Literature/IAmAmericaAndSoCanYou'', he says that it's okay to marry your cousin because Literature/TheBible [[AintNoRule 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 ''Series/TheDukesOfHazzard'':
-->'''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 ''Series/{{Seinfeld}}'' in an attempt to get his parents mad after they started neglecting him.
* On ''Series/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 ''Series/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 at the end of the episode in the form of a MundaneGhostStory.
* On the ''Series/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.
* ''Series/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, "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 ''Series/{{Friends}}'', Ross and Monica's female cousin comes to visit for the wedding, and ends up staying at Ross' apartment. After a slow-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 ''Series/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 UsefulNotes/MaryTudor and her cousin, Charles V of Spain.
* ''Series/NightAndDay'''s Tom Brake and Della Wells go much further than kissing, without realising at the time that they're biological cousins.
* On ''Series/DowntonAbbey'', a major plot point is that the Earl of Grantham is without a direct heir, and so their very distant cousin Matthew is brought in as the only suitable candidate. It is hoped that the Earl's daughter Mary will become his future wife because their marrying would ensure that Mary could keep the house and fortune she would have inherited if she had been born a boy (especially since most of the money in the estate actually came from her American heiress mother, and it would be unfair for it to go to some distant relative of Lady Grantham's husband and bypass her daughter entirely). Nobody mentions that it's technically incest, and they eventually do fall in love. If you do the calculations, they're fourth cousins. Likewise Mary had been betrothed to the previous heir (before he died in the ''Titanic'' sinking), who was her ''second'' cousin. And it's implied her sister Edith had a thing for him, too.
* The next to last episode of ''Series/{{Community}}'' takes place at Garrett's wedding. It isn't until the reception and Jeff's toast that it's discovered Garrett's great-aunt is his bride's grandmother.
-->'''Elroy:''' Now, this is a man that knows how to marry his cousin!
* Wayne and Daryl from ''Series/{{Letterkenny}}'' try to avert this, though they mention coming close a few times.
* ''Series/{{Frontier}}'': During dinner Captain Chesterfield tells Grace that he used to lust after his cousin when she was betrothed to another man. His father marked him with a hot iron after finding out that he sneaked into her bedchambers one time.

* The second verse of [[Music/WeirdAlYankovic Weird Al's]] Music/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:
-->''Who would have guessed\\
Her family crest\\
I'd suddenly spy\\
Tattooed on her thigh?\\
And son of a gun\\
It's just like the one on me...''
* [[http://www.youtube.com/watch?v=_QAgus7p3zQ Second cousin, why are you so fine?]]
* Music/ElvisPresley's song ''Kissing Cousins'' from the movie of the same name.
* Cousin Dupree by Music/SteelyDan, where the title character hits on his sexy cousin Janine and promptly receives a thorough dressing-down for being creepy and incestuous... ''which doesn't bother him at all.''
-->''Well, we used to play since we were three / How about a kiss for your Cousin Dupree?''
* Corb Lund's "Family Reunion" has a line that goes like this: "Cuz one of them I think I mighta dated back in school/ That's alright, in Alberta that's cool".
* [[http://moosebutter.com/ Moosebutter]] has a pastiche of "On My Own" from ''Theatre/LesMiserables'' called [[http://moosebutter.com/lyrics.php/jon-boy-jon "Jon Boy Jon"]] about a redneck who is in love with his first cousin.
* The eponymous Brenda in "Brenda's Got a Baby" by Music/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.]]]]

* In AlfredLordTennyson's ''Locksley Hall'', Amy, who loved and then left the narrator, is his cousin.

* 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 ''Theatre/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 ''Theatre/RomeoEtJulietteDeLaHaineALamour'' (though not [[Theatre/RomeoAndJuliet the play it's based on]]) ''wishes'' this was the case with him and Juliet.
** In most 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 [[Anime/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)]].
* 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.
* ''Theatre/{{Elisabeth}}'': like in RealLife, Franz Joseph is expected to marry his cousin Helene, only to fall in love with Helene's sister Elisabeth. It's mentioned that they're cousins, but that isn't treated as the reason their marriage [[AwfulWeddedLife ended as badly as it did]].

[[folder:Video Games]]
* As an extension for its love of the [[BrotherSisterIncest sibling version]] ''Franchise/FireEmblem'' has plenty of this:
** Several preexisting relationships in ''VideoGame/FireEmblemGenealogyOfTheHolyWar''[='s=] 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 examples in the second generation are the predestined couples of Lana/Faval and Lester/Patty. Because their mothers Aideen and Briggid were identical twins, Creator/IntelligentSystems pulled off the impressive feat of doing this and BrotherSisterIncest at the same time.
** It is possible to make Roy and Lilina from ''VideoGame/FireEmblemTheBindingBlade'' cousins... [[spoiler:by pairing Eliwood with the Pegasus Knight Fiora and Hector with either of Fiora's youngest sisters Florina or Farina]] in prequel ''VideoGame/FireEmblemTheBlazingBlade''. Since ''The Blazing Blade'' was not released yet at the time of ''The Binding Blade''[='s=] own release (and the pairings involved exist among other possible pairings), the latter never makes any mention of this possibility.
** ''VideoGame/FireEmblemAwakening'' uses a love system very similar to that of ''Genealogy of the Holy War''. 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 [[spoiler: or Emmeryn]] can also marry her cousin Inigo or Brady.
** ''VideoGame/FireEmblemFates'' allows the players to do something similar to to ''VideoGame/FireEmblemAwakening'', if they have the children of siblings marry. There are also two "set" pairs of cousins in the game, one of which can avert this or not, one of which plays it straight.
*** The first set are Asugi, the son of the {{ninja}} Saizo, and Midori, the daughter of Saizo's younger brother Kaze. ''However'', while they can reach an S-support, in the localization it ends with them as JustFriends, making them either an aversion or a straight example depending on the version itself.
*** The second set are [[spoiler:the Male Avatar and his ImpliedLoveInterest Azura--their mothers Mikoto and Arete were sisters.]] The twist is they ''[[SurpriseIncest don't know]]'' they're cousins, and they don't find out until quite late in the GoldenPath (and note, ''only'' the GoldenPath, meaning in the other two they never find out). Even after they learn the truth, though, their S-support is explicitly romantic, making them the straight example. Of course, if ''they'' don't marry each other, it's possible for their respective ''children'', who would be second cousins, to marry each other. And if [[spoiler:the Avatar marries any of Azura's children]], he/she'll end up marrying his/her first cousin once removed.
* An ill-fated romance between two 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 ''VideoGame/TheSims2'' and ''VideoGame/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}}'', TheProtagonist's little cousin Nanako tells him that she wants to marry him when she grows up, and apparently won't take "no" for an answer. If the player didn't max the link, her father won't allow it. If it's done, Doujima's gonna hold the Protagonist 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 ''VideoGame/JadeEmpire'', it's revealed that [[spoiler:Dawn Star is the long-lost daughter of Sun Li, the brother of the Emperor.]] As a result, if 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 ''VideoGame/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.
* ''VideoGame/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.
* [[BadassGay Dorian Pavus]] and a human Inquisitor in ''VideoGame/DragonAgeInquisition'' are distantly related. Dorian brings this up at one point, and if a male Inquisitor is engaged in a romance with him he has the option of asking whether it's okay to continue flirting or not. Dorian's fine with it, as it's ''very'' distant (three whole Ages, if he's being literal).
* Crawford Starrick and [[spoiler: Pearl Attaway]] are cousins as well as business partners and members of the Templar Order in ''VideoGame/AssassinsCreedSyndicate''. Dialogue between them indicates they have a long history together; having apparently been childhood sweethearts, Crawford once asked [[spoiler: Pearl]] to marry him and was deeply disappointed when she refused his proposal, as well as being clearly grief-stricken after she is assassinated by Jacob Frye (as one of his minions [[ShootTheMessenger unfortunately learns]]).
* Generally unavoidable in ''VideoGame/CrusaderKings'' if you want to keep a [[AltarDiplomacy marriage alliance]] alive for more than one generation.
* Bart and Margie of ''Xenogears'' are first cousins and engaged for [[ArrangedMarriage various political/dynastic reasons]]. Although Bart rescues her from kidnappers at one point and they do have genuine affection for each other, neither one seems to be very enthusiastic about the prospect of marriage.

[[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.
* One of the routes in the ''VisualNovel/AoiShiro'' pairs the main character up with her cousin Kaya. [[NinjaPirateZombieRobot Demon Vampire Lesbian Kissing Cousins?]]
%%* Elise from ''VisualNovel/{{Canvas 2}}''.
%%* Sakura from ''VisualNovel/DaCapo''.
%%* Nayuki from ''VisualNovel/{{Kanon}}''.
* Saki from ''VisualNovel/SnowSakura'' is a slight deconstruction. She and her cousin Yuugi fall in love but their school's vice-principle decides to butt in because their relationship isn't socially accepted. This causes drama as the two are forced to be apart. It helps that the vice-principle is depicted as a JerkAss strawman while the pairing is supported by [[CultureClash an American teacher]] and [[spoiler:their parents.]]
* ''Sono Hanabira Ni Kuchizuke Wo'': Sara and Kaede; they (at time of writing) supply the Trope Image for YuriGenre.
* Miyuki Takamachi of ''VideoGame/TriangleHeart3SweetSongsForever''. Both her status as Kyouya's cousin and potential love interest [[AlternateContinuity may or may not still be present in]] ''Anime/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]].
* 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.
* 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]].
* Sayaka from ''VideoGame/YoakeMaeYoriRuriiroNa'', although the protagonist treats her like and refers to her as his sister.

[[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]]) and through Fiona's stepparents both times, 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 ''Webcomic/TemplarArizona,'' Mose's grandfather wants 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'': Sauerkraut and Avocado'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!!!"]]
* Spoofed in ''WebComic/HarkAVagrant'': Edward the Black Prince wishes to marry his cousin, but is unable to because he needs to make an advantageous marriage. His father, Edward III, notes that it's natural to want to marry one's cousin but the realm comes first.
-->'''Edward III:''' God, the cousins I could have, but no...

[[folder:Web Original]]
* ''WebVideo/{{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.
* Of course, considering the fact that ''WebVideo/{{EpicRapBattlesOfHistory}}'' also has real-life historical figures as some of their many characters, there's bound to be at least a few lines about them having a relationship with their cousin.

[[folder:Western Animation]]
* On ''WesternAnimation/TheAngryBeavers'', the episode "Stump's Family Reunion" has Dagget trying to help [[CompanionCube Stump]] hook up with his distant cousin [[MeaningfulName Vanity]]. Norbert was there too, and intended to help (because he thought Dagget would screw up), but his help is spotty as he had an ear infection and acted goofier than his brother usually did.
* 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.
* On ''WesternAnimation/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.
