With twins, you might get [[UntoUsASonAndDaughterAreBorn a boy and]] [[HalfIdenticalTwins a girl]]. But triplets are almost always the same sex. That's what the media wants people to think. [[AlwaysIdenticalTwins Usually, they will be all identical]], but sometimes, they are all fraternal for easy recognition. In RealLife, identical twins are always both boys or both girls (for obvious reasons), but most triplets are two identical and one fraternal and only have a fifty-fifty chance of all being the same sex. All-fraternal triplets only have a one-in-four chance.

So why are Same Sex Triplets so common in fiction? Because of CastCalculus. Having one of each sex gives you balance, but three people don't divide evenly that way. So triplets are portrayed as three of a kind to give a sense of wholeness to the group. The same appeal makes RealLife Same Sex Triplets more marketable, so they are more likely to achieve fame as a group than mixed triplets. And if they happen to be children, Same-Sex Triplets are just plain [[RuleOfCute cute]].

Compare PowerTrio and RuleOfThree. Many TwinTropes also apply to triplets. If this trope is [[AvertedTrope averted]], they may be ThreeAmigos or TwoGuysAndAGirl.



[[folder:Anime & Manga]]
* Mitsuba, Futaba and Hitoha Marui from ''Manga/{{Mitsudomoe}}''.
* The Ran triplets from ''LightNovel/SaiunkokuMonogatari'', all of whom are named Setsuna. They also have personal names, but almost nobody uses them: multiple births are considered unlucky in Saiunkoku, so the triplets were raised to be as identical as possible and only the wife of one of the triplets [[spoiler:and, eventually, Shuuei]] can tell them apart.
* The Butterfly Triplets from ''VisualNovel/ToukaGettan''.
* October, November and December from ''Anime/CoyoteRagtimeShow''.
* The Hanamura Triplets from ''Manga/SallyTheWitch''.
* Ichigo, Ringo and Sango from ''Anime/HanaukyoMaidTai''.
* A set of same-sex triplets (Taichi, Tatsuji, and Yuzo Tomizawa) become murder suspects in ''Manga/DetectiveConan'', and it's up to Conan to figure out which of the three [[SelfMadeOrphan killed their father]]. [[spoiler:It was Taichi.]] In a subversion, however, The three men have pretty different looks (Taichi has a PornStache, Tatsuji slicks his hair back, Yuzo looks quite younger than the other two), and the only ''actual'' shared physical trait they have are their eyes, their brows and their noses. Which ''coincidentally'' are the only part of the culprit's face that the witnesses could see. Therefore in practice they don't look '''that''' alike, but there's still no easy way to see which triplet was to blame.
* Averted in ''Manga/GingaNagareboshiGin'', where the three Kai brothers (Akatora, Chutora, and Kurotora) are in the same litter but with different fur colors. However, this is nothing unusual because they are dogs.
* The triplets [[BewaretheQuietOnes Thompson, Timber, and Canturbury]] from the anime version of ''Anime/BlackButler''.
* Tsubaki, Azusa and Natsume Asahina from ''LightNovel/BrothersConflict''.
* In ''Manga/ACentaursLife'', ClassRepresentative [[OurAngelsAreDifferent Manami Mitami]] has four younger sisters, three of them being CatGirl triplets. They are called Chigusa, Chinami and Chiho. Collectively, they are called "[[SingleMindedTwins Chi-chan]]".

* ''Manga/OnePiece:'' The Charlotte family is shown to have a set of quadruplet brothers and one set of triplet brothers . The 5th (Opera), 6th (Counter), 7th (Cadenza) and 8th (Cabaletta) sons have identical faces and heads, but their hair and beards have different shapes and colors, though Opera looks significantly different from them due to his body being always covered in cream. The 2nd (Katakuri), 3rd (Daifuku) and 4th (Oven) sons on the other hand look completely different from each other. Other than their ginourmous height (509cm, 489cm and 492cm, respectively), it is impossible to tell that they are triplets or even related to each other.

[[folder:Comic Books]]
* The Kleinstocks (Sven, Harlan, and Eric), Creator/MarvelComics supervillains.
* Also from Creator/MarvelComics, the Stepford Cuckoos, for a time [[spoiler:when three of them were still alive, and before they discovered their innumerable clone siblings]].

[[folder:Films -- Animation]]
* ''WesternAnimation/TheTripletsOfBelleville'' are three ancient ex-cabaret performers who spend their days playing jazz on improvised instruments and dynamiting frogs for their dinner. They're drawn very differently even when young, and as old women they're easy to tell apart.
* Identical triplets identified in the credits as "Bimbette 1, 2 and 3" appear in ''Disney/BeautyAndTheBeast''.
* Averted in the ''WesternAnimation/{{Shrek}}'' series; Shrek and Fiona's triplets are two boys and one girl.

[[folder:Films -- Live-Action]]
* Lisa, Jessie and Megan Wyatt from ''Film/TheParentTrap III''. Interestingly, while the twins were played by the same actress (Creator/HayleyMills), the triplets were played by real-life triplets Leanna, Monica and Joy Creel.
* When Bowen comes to Kara's village in ''Film/{{Dragonheart}}'' and suggests that they sacrifice a virgin to get the dragon to leave them alone, the father of identical dark-haired triplet girls freaks out because Bowen is looking at his daughters.
* In ''Film/PacificRim'', the Chinese ''[[HumongousMecha Crimson Typhoon]]'' is piloted by the [[http://media.monstersandcritics.com/articles3/1716782/article_images/SSKH19735r.jpg Wei Tang Triplets]].

* The Sisters of Orion in the ''Literature/{{Alterien}}'' series. They are Vasja'ri, T'aryn and Re'nara.

* The Roze brothers from ''Literature/GarrettPI'' '''might''' qualify, if puny Dojango and colossal [[GenderBlenderName Doris and Marsha]] really are triplets. But then, there's that whole "[[BizarreAlienReproduction different mothers]]" issue that Garrett refrained from asking about...
* Lily, Rose and Violet from ''Literature/TheSecretOfPlatform13''. They're also identical, which was part of the reason the King and Queen hired them: it would give the young prince the security of one constant helper but could provide three times the work.
* Though there are quite a few sets of triplets in ''Literature/WarriorCats'', this trope is almost always averted. Possibly the only example of it being played straight is with Crookedstar and Willowbreeze's kits: Willowkit, Minnowkit, and Silverkit ([[spoiler:though only Silverkit survives the illness that kills her sisters and mother just after their birth]]).
* Elk-Frodi, Thorir Dogfoot and Bodvar Bjarki from the ''Literature/SagaOfHrolfKraki''. Thorir and Bodvar would be identical if Thorir didn't have dog paws for feet because of a curse.
* ''Literature/Paperquake''. Partially subverted as only two of the three sisters look identical, with the third sister Violet often feeling left out of the triplet bond.
* The three Ravers in ''Literature/TheChroniclesOfThomasCovenant'', who were "three brothers of one birth". Of course, by the time the books take place they've transformed into bodiless, possessing demon spirits and as such don't really have a sex ''per se'' at all, they're still referred to with male pronouns when any gender is applied.
* The Princesses of Ruwenda in ''Literature/BlackTrillium'', who are not only all fraternal but [[PowerTrio play into]] [[BlondeBrunetteRedhead multiple]] [[BeautyBrainsAndBrawn triplicate]] [[FreudianTrio tropes]]. (Then again, the entire book—as one might have guessed from a title referencing a [[https://en.wikipedia.org/wiki/Trillium flower]] with trilateral symmetry—runs on the RuleOfThree.)
* Zigzagged in one book of the ''[[Literature/SweetValleyHigh Sweet Valley Twins]]'' series. Jessica and Elizabeth convince a new acquaintance they don't like that they're actually triplets; they take turns playing the third sister, Jennifer.

[[folder:Live-Action TV]]
* Tracy, Niki and Barbara from ''Series/{{Heroes}}'', all of them played by Ali Carter. Not only are they SeparatedAtBirth, they also have completely different powers (Barbara's are unknown). Niki has SuperStrength and Tracy is AnIcePerson.

* Averted in Aussie soap opera ''Series/{{Neighbours}}'', where magnate Paul Robinson's triplets were one daughter and two identical sons ([[EvilTwin one of whom was evil]]).
* ''Series/PairOfKings'' featured Brady, Boomer and Boz. PlayedForLaughs since the triplets are obviously fraternal (especially since one is black and the other two are white).
* Charlotte and Cooper's triplets on ''Series/PrivatePractice'' are all girls, named Georgia, Caroline, and Rachel.
* The basic principle of this trope is averted in the short-lived sitcom, ''Quintuplets.'' Of the titular quints, there were three boys and two girls, all apparently fraternal.
* Rudy, from ''Series/{{Misfits}}'', is introduced with the power to split off a physically identical duplicate of himself (who happens to embody his more sensitive, kinder, responsible side), but it's revealed sometime later that there's actually a ''second'' [[GoodAngelBadAngel duplicate who is kind of a psycho but has been locked up in jail]]. [[EvilTwin He gets released, forcibly re-merges with the others, and takes control of the unified persona.]]
* On the first episode of ''Series/MorkAndMindy'', while Mork is in the 50s visiting The Fonz and wants to experience human dating, Fonzie tries to think of whom he could get. Fonzie mentions "the Hooper triplets" commenting, "Now there's a six-pack to go."

[[folder:Myths & Religion]]
* Although there are many triplicate goddesses in various European mythologies, such as Hecate or the Norns, the differentiation into the [[TheHecateSisters Maiden, Mother and Crone]] wasn't invented before the 19th century.

An Empress of Orlais in the Steel Age was believed to have given birth to only one daughter, but adopted two lookalikes as protection against assassination, and the princesses were presented to the public as triplets. According to the children's rhyme about the phenomenon, two of the girls were indeed murdered, with the survivor claiming the throne - and no one sure whether or not she was the true heir.

** The titular trio of brothers. Although some sources give them different ages, they're actually triplets.

* Triplets played baby Katie on ''Series/DrQuinnMedicineWoman'', enabling her to be frequently seen on-screen without ever violating SAG rules or child-labor laws about the amount of hours a child can work. Most shows with babies use twins for this reason, but for Katie, ''triplets'' were needed.
* In the ''Series/LawAndOrder'' episode "Phobia," the baby boy was played by real life triplets [[http://articles.mcall.com/2001-02-10/news/3345922_1_law-order-triplets-show Drew, Rob, and Kyle Lichtenwalner]].
