->"I've known Barbie since we were in matching cribs!"
-->-- '''Midge''', ''WebAnimation/BarbieLifeInTheDreamhouse''

There are many kinds of friendship: work friends, school friends, drinking buddies and more. Yet one of the [[BestFriend very closest types of friendship]] is that of Childhood Friends. Before you have to worry about the shock of betrayal or the possibility of romance, this is the friend that will always have your back. No one knows you better than them. And it shows when childhood friends are treated more intimately or are trusted more than other friends.

Since many friends have known each other since childhood, a duo of them could become HeterosexualLifePartners or RomanticTwoGirlFriendship if of the same gender or PlatonicLifePartners if of the opposite gender, but this does not mean romance as what binds them together is the experiences they had since they were children.

Supertrope of ChildhoodFriendRomance, PatientChildhoodLoveInterest, BeleagueredChildhoodFriend, ForgottenFirstMeeting and ForgottenFriendNewFoe.

[[folder:Anime & Manga]]
* ''Franchise/LoveLive'': Honoka, Umi, Kotori, and (manga-only) Eli. Umi claims to be ''super childhood friends'' with Honoka because their mothers were childhood friends too.
* ''Anime/LoveLiveSunshine'': Chika is this with Kanan. The anime reveals that she has this sort of relationship with You Watanabe as well.
* Nagi, Sakuya, Wataru and Isumi are all childhood friends in ''Manga/HayateTheCombatButler''. While Wataru does like Isumi, for the most part it's entirely platonic. A large portion of the cast dynamics revolves around their relationships together. And surrounding them is their families and how ''they'' interact. In fact, they seem to be {{Generation Xerox}}es to an extent, though their parents are very minor characters.
* Reinhard von Lohengramm and Siegfried Kircheis in ''Anime/LegendOfGalacticHeroes'' had a bromance as epic as the title of the show. Their shared childhood memories were commonly shown in flashbacks.
* Lelouch and Suzaku in ''Anime/CodeGeass''. Basically the only reason why Lelouch didn't brainwash or kill him early on. At some point, Lelouch says, "You're the only one I didn't want to use the geass on," referring to Suzaku, and the reason he did it was to force Suzaku to save himself (when he's planning to sacrifice himself to take down Zero), other than that one time Lelouch doesn't care who he brainwashes.
* ''Manga/{{Haikyuu}}'' has three canon sets of childhood friends:
** Tsukishima Kei and Yamaguchi Tadashi. Tsukishima stopped a few kids from bullying Yamaguchi when they were little; as a result, Yamaguchi followed Tsukishima in joining the volleyball team. Yamaguchi is also the only one is allowed to call Tsukishima 'Tsukki' without the latter getting angry.
** Kuroo Tetsurou and Kozume Kenma. They are neighbors and attend Nekoma High School together, and are both on the volleyball team. Kuroo makes sure Kenma is included in everything he does, and Kenma plays volleyball because he knows that Kuroo likes playing with him.
** Oikawa Tooru and Iwaizumi Hajime. They also started out as neighbors when they were small children and have grown into a strong duo on the court. Iwaizumi almost aggressively cares about Oikawa, making sure he doesn't stay up too late or put to much stress on his bad knee.
* ''Manga/{{Bleach}}'':
** Ichigo and Tatsuki are childhood friends. They grew up together, trained at the same dojo, and Tatsuki recalls how much his mother's death affected his family. Ichigo, most of all. Though she eventually laments how much they've grown apart over the years[[note]]after punching him through a window, headfirst, for not telling her the truth about Orihime's disappearance and about the things she'd seen him getting involved in[[/note]], due to Ichigo [[LockedOutOfTheLoop gradually shutting her out]].
** Rukia and Renji ran with a gang during their childhood years in the Rukongai 78th District. Once their three friends died, they travelled together to Seireitei to train to become Shinigami whereupon events separated them for over forty years before their friendship was able to be renewed at the end of the Soul Society arc. Renji was inspired by Ichigo's strength to turn traitor to Soul Society and help Ichigo save Rukia from the executioner's block as a result of his childhood friendship with Rukia. [[spoiler:The epilogue reveals that they eventually [[ChildhoodFriendRomance get together]] and have a daughter.]]
** Hitsugaya and Hinamori are childhood friends of the brother/sister type. Since blood families are almost unheard of in the Rukongai, families of adopted strangers spring up instead. One old woman in the 1st District became a grandmother to both Hitsugaya and Hinamori and raised them together. Hitsugaya's conflict with Aizen becomes more personal than the conflict between Aizen and other captains because of Aizen's exploitation of Hinamori and Hitsugaya's desire to protect her. This gets much, much worse before it gets better.
** Gin and Rangiku were childhood friends in the Rukongai. Gin found Rangiku collapsed and offered her food. From that day, they travelled together until they became Shinigami. [[spoiler: Gin joined Aizen on a century long quest for vengeance because of a past attack by Aizen on Rangiku which was what led to her collapsed state when she and Gin first met.]]
** Ryuuken Ishida and Kanae Katagiri were introduced to each other as very young children. Kanae was supposed to be Ryuuken's personal servant and bodyguard, but they were so close that, by the time they'd reached their late teens, she was also his battle partner and confidante. [[spoiler:They eventually marry and have Uryuu. Her tragic death is one of the biggest reasons for why Ryuuken hates Quincies and doesn't want Uryuu to be one.]]
* Kyouko and Sho in ''Manga/SkipBeat'' were friends in childhood, and know each other just as one would expect with all those years of experience... although calling them "friends" currently would be something of a mistake.
* Grizzly Bear and Polar Bear of ''Manga/ShirokumaCafe'' have known each other since they were cubs. Polar Bear's laid-back personality and fondness for trolling his friends plays off beautifully against Grizzly's more tempestuous and grumpy personality.
* ''Anime/TamakoMarket'':
** Not only is Mochizou a childhood friend of Tamako, he is also the son of the owner of Rice Cake Oh! Zee and thus works for the competition. No, they aren't really in a romance yet, although Mochizou has some interest in Tamako. [[spoiler:They get RelationshipUpgrade in TheMovie ''Tamako Love Story''.]]
** Tamako's childhood friend, Midori, has been friends with her since grade school. [[SchoolgirlLesbians She has feelings for Tamako as well.]] [[spoiler:She never confesses and it never goes anywhere]].
* Hiyori and Manabe in ''Manga/KotouraSan''. Hiyori is interested in Manabe, but Manabe sees her as just a friend. And quite a bit less than that after he found out that she was responsible for four grown men sending him to the hospital with serious injuries.
* Veronica and Carlo of ''Manga/BokuraNoKiseki'' were raised in the same monastery together.
* Pictured above: The entire premise of ''Anime/AnoHanaTheFlowerWeSawThatDay'' revolves around a group of six childhood friends who drifted apart after one of them (Meiko aka Menma) dies and years later, Menma appears as a ghost asking Jintan to have a wish granted, but she doesn't know that wish, so he gathers around his old friends to help solve his problem.
* In ''Manga/KOn'', Yui and Nodoka. Also, Mio and Ritsu. This becomes a bonding point between Mio and Nodoka in the second year (when they're not in the same class as Ritsu, Yui, or Tsumugi) as they compare notes on what it's like being the more responsible member of a pair of childhood friends.
* ''Manga/MakenKi'': Takeru has known both Haruko and Inaho since childhood; albeit at different times:
** Takeru knows Haruko from the time they spent together at his father's dojo, where they used to spar. Haruko developed a crush on him during that time, [[CannotSpitItOut but she refuses to admit it.]]
** In Inaho's case, Takeru was her only friend as a kid, because her father was strict with her [[spoiler: out of fear that she'd leave him]]. So [[http://readpanda.net/Maken-ki/59/7/ the time]] [[http://readpanda.net/Maken-ki/59/9/ they spent together]] is an important memory for her.
* ''Anime/ShimaShimaToraNoShimajiro'': Shimajiro, Mimirin, Torippii, and Ramurin. Ramurin eventually moved away and was replaced by Nyakkii.
* In ''Manga/ShinryakuIkaMusume'', Eiko says she and Goro and childhood friends, and, well, that's pretty much all there is to that. She doesn't have eyes for him, and he has eyes for her older sister.
* ''Anime/VariableGeo'': The OVA depicts Yuka and Satomi as having grown up together [[FriendlyRivalry as sparring partners at her grandfather's dojo.]] They've drifted apart over the years, but their bond remains as strong as ever.
* Haruka, Makoto, Nagisa and Rin from ''Anime/{{Free}}'' were friends in elementary school until they went their separate ways when Rin went overseas to Australia to go study. When they are reunited years later, the three remaining guys saw Rin's personality changed and he declares Haruka as his rival. In the first season's final episode, [[spoiler: Rin makes up with his old friends, which culminated in them shared a big hug at the end.]]
* Ryu, Shota and Chizu of ''Manga/KimiNiTodoke'' were friends when they were a lot younger; Ryu and Chizu have been friends pretty much their entire lives.
* ''Anime/LupinIIIDragonOfDoom'': Goemon and Kikyo, though he is a few years older at least. [[spoiler:Sadly, she turns out to be EvilAllAlong. ]]
* ''Manga/PandoraHearts'' has two very different examples:
** [[NeverMessWithGranny Sheryl]] [[HandicappedBadass Rainsworth]] and [[OlderThanTheyLook Rufus]] [[TheChessmaster Barma]] swore to work together to prevent another [[CataclysmBackstory Tragedy of Sablier]] from occurring, even if their respective families' interests ever came in conflict. [[HopelessSuitor Rufus]] is also her [[ChildhoodFriendRomance Unlucky Childhood Friend]] and [[{{Determinator}} kept asking for her hand in marriage from their student years to present time.]] Sheryl is in her seventies and married to someone else, but as Rufus puts it, "a divorce can fix that!"
** [[TheChewToy Gilbert]] and [[HairOfGoldHeartOfGold Ada]] [[ShelteredAristocrat Vessalius]], who have known each other since they were nine and three years old respectively, are LikeBrotherAndSister. Ada is the only member of the Vessalius family Gilbert didn't hide from after [[spoiler: betraying the Vessalius by [[FeudingFamilies becoming a Nightray.]] His motive for said betrayal was to rescue [[GuileHero Oz]], Ada's older brother, from [[EldritchLocation the Abyss]], so it was only ever a betrayal [[HeroicSelfDeprecation from his point of view]].]]
* In ''Manga/{{Saki}}'', Satomi Kanbara, president of the mahjong club of Tsuruga, is childhood friends with Kaori Senoo, and knows that Kaori will join on her request that the Tsuruga team will have enough members to enter the tournament. While Kaori has no experience playing mahjong, she has incredible BeginnersLuck, and does fairly well in her round.
* [[spoiler:''Both'' Sena and Yozora]] are this to Kodaka in ''LightNovel/BokuWaTomodachiGaSukunai''
* In ''Anime/PuellaMagiMadokaMagica'', Madoka Kaname met Sayaka Miki (and to a lesser degree, Kyousuke Kamijou) in kindergarten. In primary school, Hitomi Shizuki joined them.
* Chiya and Sharo in ''Manga/IsTheOrderARabbit'', since they both live right next to each other.
* Two pairs in ''Manga/TonariNoKashiwagiSan'', Kotone and Sayaka, and Yuuto and Kazuki have known each other since they were small.
* ''Anime/CrossAnge'' has Ange and Momoka who were raised together ever since the latter met the former and already knew she was a [[AntiMagic Norma.]]
* ''LightNovel/TheAsteriskWar'':
** Amigiri Ayato and Sasamiya Saya knew each other since they were kids but lost contact with each other when Saya's family moved 6 years prior. They reunite the day after Ayato transferred to Seidoukan Academy (they would have reunited much sooner but Saya slept in that day and missed school).
** In the 6th volume, we learn that Julis-Alexia van Riessfeld and Orphelia Landlufen were this as well.
* Jurai and Hatoko of ''LightNovel/WhenSupernaturalBattlesBecameCommonplace'' have known each other since elementary school and supported each other the whole time up to high school. Hatoko very much wants it to become a ChildhoodFriendRomance.
* In ''LightNovel/HowToRaiseABoringGirlfriend'', Tomoya and Eriri bonded through their shared otaku interests in their elementary school years. While events caused a rift in their relationship for some time, they still help each other out when they're in high school.
* Akina and Chigusa of ''Manga/ShinozakisanKiWoOtaShikaNi'' are shown to have been friends since preschool and are still close even though they now go to different high schools.
* ''Manga/YourLieInApril'' features few examples:
** Watari, Kousei, and Tsubaki, who have known each other since they were kids.
** Emi and Takeshi who've known each other ever since they started competing in piano competitions as children.
* There are three sets of childhood friends in ''Manga/MahouSenseiNegima'', two of them fall under ChildhoodFriendRomance, but there's one that ([[LesYay mostly]]) lacks any romantic subtext: When Ayaka first met her in preschool, Asuna was an EmotionlessGirl since [[spoiler: she had her memory wiped after spending at least 150 years as a living weapon]]. So Ayaka attacked her [[VitriolicBestBuds and it defined their relationship ever since]]. Near the end of the manga Asuna says that meeting Ayaka was "the best luck she ever had" and [[spoiler: Ayaka lived to 115 out of sheer willpower when Asuna had to go away for 100 years. Too bad Asuna had to oversleep and wake up long after Ayaka passed away.]]
* ''Anime/{{Pokemon}}'':
** In ''X/Y'', Ash finds himself meeting up again with Serena, a girl he met when he was younger. A downplayed version though, since they only met at summer camp and [[ForgottenFirstMeeting Ash didn't even remember Serena]] until she returned the handkerchief he lent her. Serena [[ChildhoodFriendRomance nurses feelings for Ash]] as a result of said meeting, but [[ObliviousToLove Ash is unaware of them]]. [[spoiler:That is, until Serena [[TheBigDamnKiss plants a goodbye kiss on him]] as they part ways at the end of the series.]]
** Dawn, Leona, and Kenny have known each other since kindergarten. Kenny is an {{expy}} of TheRival from ''VideoGame/PokemonDiamondAndPearl'', who is also a childhood friend. Barry eventually appeared in the anime himself but isn't friends with Dawn.
* Kaname Tsukahara, Shun Matsuoka, and Yuki & Yuta Asaba from ''Manga/KimiToBoku'' have known each other since kindergarten. [[spoiler:Even the NewTransferStudent met the twins when he was younger, but they only briefly played together]].
* ''Franchise/LyricalNanoha'':
** Nanoha, Fate, Yuuno, and Hayate met when they were nine, so by the time of ''[[Anime/MagicalGirlLyricalNanohaStrikers StrikerS]]'' they're referred to as childhood friends. Although, [[WordOfGay Nanoha and Fate's relationship]] technically falls into [[ChildhoodFriendRomance a different category]].
** Nanoha had also been friends with Arisa and Suzuka for several years before she met Fate.
** Shario and Griffith grew up in the same neighborhood.
** Fuka and Rinne from ''Anime/VividStrike'' grew up in an orphanage together, and Fuka often defended Rinne from bullies. Sadly, [[WeUsedToBeFriends their friendship fell apart]] about a year before the season began due to Rinne's change in personality after being adopted into the Berlinetta family. The season even revolves around Fuka trying to reconnect with Rinne in the [[DefeatMeansFriendship traditional]] ''Nanoha'' fashion.
* In ''Manga/{{Aruosumente}}'', Legna and Emperor Artian. Since Legna's father served Artian's father as an Oracle and Legna was meant to be raised as secluded as possible, Artian was the only other child he had any contact with and they became friends. By the time of the prsent story, however, the two have grown apart due to Artian's carefree nature and Legna's tendency towards AngerBornOfWorry.
* Kanako and Takatsuki from ''Manga/WanderingSon'' have been friends since kindergarten, though they don't actually seem too close compared to the others. In a noticeable case of CharacterizationMarchesOn, the first volume has Kanako as a nameless extra. Takatsuki didn't initially know about her [[TheDitz scatterbrained personality]], but by volume two shows they've been friends for years.
* Takeo and Suna from ''Manga/MyLoveStory'' live next to each other and their mothers are friends. They've been best friends since elementary.
* In ''Anime/{{Endride}}'', Alicia is Emilio's childhood friend (and possibly only his friend before the series starts), but while she's the very model of a childhood friend toward him, at some point she and the others acknowledge that he hasn't been the best friend back, which causes her to hesitate over whether she wants to turn it into a ChildhoodFriendRomance or not.
* In ''Manga/Brave10'', Anastasia and Saizo are childhood friends from their {{ninja}} training days who are reunited as Braves at the start of the series. There's also an important ForgottenFallenFriend from childhood in Saizo's backstory that sets the stage for his fear of serving a master and opening himself up to others, after seeing his friend who was TheAce go off to serve someone only to be easily thrown away in the end.
* Tomoe and Shutaro of ''Manga/SilverNina'' have known each other since childhood, having grown up together in the same small town. Much of the tension between them stems from Shutaro's failed attempt to make it big in The Big City and having to come back to their small town.
* ''Webcomic/AxisPowersHetalia:'' [[TheGunslinger Switzerland]] and [[PrincelyYoungMan Austria]] were this, though Switzerland was [[WhyCouldntYouBeDifferent disappointed]] with Austria's [[NonActionGuy lack of fighting ability]]. They had a falling out, and [[SheIsNotMyGirlfriend neither likes to be reminded of how close they were]] when they were children. [[DeadpanSnarker Norway]] and [[PerpetualSmiler Denmark]] were this as well, but unlike the former, they remain [[OddFriendship close]] in the present, to the point that Denmark refers to Norway as "best buddy" and "brother," and Norway refers to Denmark as ''anko,'' a term analogous to ''onii-chan''[[note]]The familiar/most intimate form of "big brother"[[/note]], which is usually rendered as "brother" or "bro."
* Yuri, Yuko, and Takeshi from ''Anime/YuriOnIce'' have all known each other since childhood, having met when they were learning how to skate at the same rink. Takeshi was initially a bully towards Yuri, but their relationship improved over time. Yuri also had a crush on Yuko, but she went on to have a ChildhoodFriendRomance with Takeshi, eventually marrying him and having triplets.
* Mello and Matt from ''Anime/DeathNote'' grew up together at the same orphanage, and still appear to be each other's OnlyFriend when they're hitting their twenties.
* In ''Manga/Classi9'', Liszt and Chopin have known each other for most of their lives and are now HeterosexualLifePartners. Liszt became very good at dealing with illnesses because he has been taking care of [[IllGirl Chopin]] for so long, and Chopin has seen his friend's [[SplitPersonality "possessions"]] increase with time, which makes him one of the rare people able to bring Liszt back without getting hurt.
* ''Manga/ScumsWish'' has two sets of childhood friends -- Hanabi and Narumi, and Noriko and Mugi. In both cases [[ChildhoodFriendRomance the former has feelings for the latter]].
* ''LightNovel/MagicalGirlRaisingProject'':
** Snow White and La Pucelle were friends who bonded over their shared love of Magical Girls in elementary school. They separated in middle school, but happily reunited when both of them became Magical Girls and quickly partnered up.
** Shadow Gale and Pfle have known each other since they were young children. Shadow Gale is Pfle's servant, but the two are very close, and Pfle cherishes Shadow Gale dearly. Shadow Gale has issues with Pfle's pranks and willingness to do dark deeds, but she still cares for her and wishes she'll become a better person.
** Captain Grace and Funny Trick have been glued at the hip since elementary school, with Grace always eager to protect Funny Trick and bring her along with her adventures. [[FalseFriend Funny Trick is less enthused about their relationship]], not wanting to be friends with a person as scary as Grace even as she reluctantly goes along with her.
* ''Manga/KaguyaSamaWaKokurasetai'' has Kaguya and her personal maid Hayasaka. The two have basically been inseperable since they were seven and WordOfGod states that they view each other more as sisters than mistress and servent.
* Hori and Sengoku from ''Manga/{{Horimiya}}'' have been friends for a very long time, long enough that Hori has no trouble getting changed in front of him (something that Hori doesn't even feel comfortable doing in front of her boyfriend [[spoiler:despite the fact that they've already had sex]]). It's also implied that they were still bathing together until very recently.
* Link, the son of the Hyrule Knights captain, and Princess Zelda in the ''Manga/TheLegendOfZeldaFourSwordsAdventures'' manga have been good friends since they were young.
* Everyone in ''Manga/KomiSanWaKomyushouDesu'' has some kind of oddball quirk. Najimi Osana's is being literally ''everybody's'' childhood friend. Every member of the cast has met and known Najimi at some point in their elementary or middle school lives since they transferred a lot. When put in Japanese, surname-first order, the name "Osana Najimi" literally means "childhood friend".
* Played with in ''Literature/SoundEuphonium''. Kumiko and Shuuichi have known each other for years and are treated as childhood friends, however it's noted that Shuuichi ignored Kumiko in middle school. The two have a very strained "friendship". Shuuichi has a crush on Kumiko but it's unrequited and she's [[ObliviousToLove completely ignorant of it]]. [[spoiler:In the original books, they ended [[ChildhoodFriendRomance a couple]].]]
* ''Manga/CaptainTsubasa'':
** Tsubasa arrived to Shizuoka when he was 11-12, so he considers the members of the Nankatsu soccer team (Ishizaki, Misaki, Wakabayashi, etc.) plus Manabu and Sanae as his childhood friends. [[spoiler: In the specific case of Sanae, it goes into ChildhoodFriendRomance.]] Tsubasa's mom lampshades it in the original anime, when she says that up until Tsubasa joined the team, he had very few friends.
** Tsubasa also was childhood friends with Yayoi, and he actually was her FirstLove. [[spoiler: Her almost-boyfriend, Misugi, ''also'' counts in the end.]]
** When Genzo moved to Germany with Mikami at age 12 and was bullied by the younger members of the Hamburg Team, Schneider treated him as a WorthyOpponent instead. He also soon befriended Kaltz, and according to ''Road to 2002'' he considers the two as childhood friends too.

[[folder:Audio Plays]]
* [[PlayerAndProtagonistIntegration You]] and Mark in ''[[AudioPlay/ChooseMe Choose Me: Mark or Doug]]''. The two of you have known each other since you were kids and are now coworkers as well as friends.

[[folder: Comic Books]]
* Archie and Jughead from ''ComicBook/ArchieComics'' have been best friends for years. Betty is usually also Archie's childhood friend.

[[folder:Fan Works]]
* In ''Franchise/TheMatrix''[=/=]''Series/{{Supernatural}}'' crossover ''Fanfic/HuntingSeries'' there's Dean, Sam and Tom after John Winchester saved Tom from vampires. It really starts after the three boys play tag around the Impala setting them to be friends for life.
* [[WesternAnimation/TheLegendOfKorra Bolin and Asami]] in ''FanFic/ForcedToBeAFamily''. They meet when Hiroshi stops by the police department to identify a suspect in his wife's murder and brings Asami along with him, and Bolin (living at the station as Lin's charge) invites her to play a few games of "Avatar".
* In the ''Franchise/{{Naruto}}'' fanfic, ''FanFic/WindMonkBanishment'', Fuu and Shibuki have known each other since childhood and remain close. He's probably the only person Fuu respects and considers a dear person next to Naruto.
* ''FanFic/TheDifferentverse'': Twilight and Moondancer met and became roommates when they were eleven, though it took Twilight a year to admit they were actually friends.

[[folder:Films -- Animation]]
* Manolo, Maria and Joaquin in ''WesternAnimation/TheBookOfLife''.
* Ronin and Queen Tara in ''WesternAnimation/{{Epic}}''.
* Kenai and Nita from ''Disney/BrotherBear2''.
* ''Disney/{{Bambi}}'' has Thumper, Flower, and Bambi meeting as children and then being reunited as adults. Bambi also briefly befriended his [[ChildhoodFriendRomance future mate]] Faline, however they don't get much screentime in the original film. ''Disney/{{Bambi II}}'' expands on Bambi and Faline's relationship as fawns.

[[folder:Films -- Live-Action]]
* ''Film/ThorTheDarkWorld''. As it turns out, Thor and Sif have been close friends since childhood, with Sif [[ChildhoodFriendRomance having developed romantic feelings for him]] (implied in [[{{Film/Thor}} the first film]] and now confirmed) and platonic feelings from his end (or possibly unrealized romantic feelings, as it's also been confirmed that there will be a LoveTriangle between Thor, Sif, and Jane in the sequel).
--> ''Jaimie Alexander:''' She cares about him. They grew up together, you know?
* The Flatbush Four in ''Film/LastVegas''
* Alex Stewart and Rosie Dunne in the movie adaption of ''Love Rosie''.

* Marco and Jake in ''Literature/{{Animorphs}}''.
* One of Larry's regrets in ''Literature/TheStand'' was how he ruined a childhood friendship by quibbling over a small amount of money when he knew perfectly well he was wrong. It's one of the memories he holds to convince himself that he 'aint no nice guy.' We never see his friend in the present (he probably died in the [[ThePlague superflu pandemic]]), but it clearly bothers Larry at how pointlessly selfish he was and how he lost a really good friend over it.
* ''Literature/CaptainUnderpants'': George and Harold first became the best of friends in Kindergarten. [[WesternAnimation/CaptainUnderpantsTheFirstEpicMovie The movie]] expanded on this very fact.
* [[TheHero Derek]] and [[IceQueen Laura]] of the web-novel ''Literature/{{Domina}}''. She moved away years ago for reasons he doesn't understand--all she'll say is that its his fault.
* Cassel and Lila from ''Literature/WhiteCat'' by Creator/HollyBlack.
* Polly Plummer and Diggory Kirke in ''Literature/TheChroniclesOfNarnia''. They meet in the first book ''The Magicians Nephew'' and the final book, ''The Last Battle'' reveals they kept in contact their whole lives.
* Though the two actually met as first-year midshipmen at Saganami Island and not as children, Michelle Henke otherwise fills this role for Literature/HonorHarrington; when Henke is introduced in ''The Short Victorious War'', she is quickly established as Honor's oldest and closest friend. Though the two spend months and even years apart -- and endure reciprocal cases of ReportsOfMyDeathWereGreatlyExaggerated -- their friendship is a running thread throughout all subsequent novels; Honor is always at her easiest and most uninhibited with Michelle, no matter how many other close friends she makes throughout her life.
* In ''Literature/TheHungerGames'', Delly Carwright and Peeta are of the LikeBrotherAndSister variety.
* In ''Literature/TheWitchlands'':
** Safi and Prince Leopold used to be great friends as kids, but were forced to stop meeting when his status and her family's situation put them apart. Nevertheless, when they meet for the first time in years, they're immediately friends again.
** Vivia and Merik used to be best friends with Serrit Linday, but as they grew up, Serrit's political ambitions [[spoiler:and allegiance to the Big Bad]] put them at odds.
* In ''Literature/AllOurYesterdays'', Marina and James met as children. As teenagers it blossoms from friendship into romance.
* ''Literature/WarriorCats'': Firestar, Graystripe, and Ravenpaw met when they were barely of apprentice age but stayed close friends the rest of their lives.

[[folder:Live-Action TV]]
* The reason Mike stuck around his poisonous best friend Trevor for so long on ''Series/{{Suits}}'', even after Trevor ruins his dream of becoming a lawyer, is because Trevor and Mike are each other's oldest friends.
* Monica and Rachel from ''Series/{{Friends}}''.
* The five friends on Creator/DisneyChannel's ''Series/IDidntDoIt'' know each other ever since when they were on third grade.
* ''Series/DoctorWho'':
** The Doctor and the Master were grew up together on Gallifrey and were close friends. It ended badly, but occasionally they are still on FriendlyEnemy terms.
** Amusingly deconstructed with Runcible in "The Deadly Assassin" - he and the Doctor were apparently schoolfriends and are still reflexively fond of each other, but when they try talking together their conversation is comically awkward and they have little in common, in a very school reunion-type manner. They mostly make awkward small talk about how many times the Doctor has regenerated and try to avoid meeting each other's eyes.
* In ''Series/BrooklynNineNine'' Detective Jake Peralta and Gina Linetti, the precinct civilian administrator, grew up together as kids. This doubles as an ActorAllusion, as Creator/AndySamberg (Jake) and Creator/ChelseaPeretti (Gina) also were childhood friends.
* In ''Series/ItsAlwaysSunnyInPhiladelphia'', Mac and Charlie have been friends since childhood.
* Clarke Griffin and Wells Jaha from ''{{Series/The 100}}'' have been friends since they were little.
* ''Series/TeenWolf'': HeterosexualLifePartners Scott and Stiles have been friends their entire lives. [[{{WordOfGod}} According to the actors]] they met in the sandpit in kindergarten, Stiles peed on Scott's sandcastle (the context is never explained) and they've been inseparable - and each other's OnlyFriend - ever since.
-->'''Dylan O'Brien (Stiles):''' And there's really nothing beyond that, it's just we met in the sandbox when we were four and we've been best friends ever since and we felt 'eh, no need to make any other friends, it doesn't matter.'
* ''Series/{{Arrow}}'': Oliver Queen, Tommy Merlyn, and the Lance sisters, Laurel and Sara, all grew up together. [[ChildhoodFriendRomance Oliver and Tommy both had relationships with Laurel at different points]], and Oliver even cheated on Laurel with Sara (during the inevitable boat trip that would change all their lives forever). Tommy and Sara had no romantic inclinations with each other as far as what is shown, though considering the incident with the ''Queen's Gambit'' pretty much stalled that opportunity until it was gone, one has to wonder if it would've only been a matter of time otherwise.
* ''Series/IntoTheBadlands'': Veil and Jade are informed to have been this. However it's treated [[ContrivedCoincidence in a rather contrived way]] since their reunion (ushered by Jade's plea for [[TheMedic Veil]] to save her secret lover Ryder's life) was used as a plot device to get Veil involved in the political drama of the regents and to snowball Quinn's VillainousCrush on her. After they share a very brief moment on-screen together, they are never seen talking or even speaking of one another again.

* Subverted in ''Radio/NewDynamicEnglish'', where [[spoiler: the mysterious "brother" who unintentionally harassed Max on the phone is actually Bobby King, Max's childhood friend. Max and Bobby were close friends to the point where they called themselves brothers until Max was about five years old, when Bobby moved away (most likely to New York).]]
* ''Radio/PokemonTheBirthOfMewtwo'': We have Mewtwo, Ambertwo, Bulbasaurtwo, Charmandertwo, and Squirtletwo. Too bad the last four all died before they even woke up...

* The ''Franchise/{{Bratz}}'' girls have known each other (and the Tweevils in [[WesternAnimation/{{Bratz}} the 2004 cartoon]]) since they were toddlers, hence the ''Bratz Babyz'' SpinOff.

[[folder:Video Games]]
* ''[[VideoGame/AdvancedVariableGeo Advanced V.G.]]'': As in their OVA portrayal, Yuka Takeuchi and her best friend, Satomi Yajima, have known each other since childhood. They grew up together [[OneOfTheBoys as sparring partners]] at her grandfather's dojo and [[FriendlyRivalry have been competing against each other]] for just as long.
* Yuuki and Heita in ''BigBangAge''. Yuuki is apparently one of Heita's only real friends and the two are rather close. He's rather... surprised to learn [[{{Bifauxnen}} the truth]] about Yuuki, too. Both are rather minor characters, though, so the relationship isn't as fleshed out as it could be.
* In the mage starter area in ''VideoGame/DragonAgeOrigins'', the player character and Jowan are quickly established as having been close friends since the age of five or six -- this is probably a deliberate attempt to make the player more inclined to go along with Jowan's (illegal, and questionably moral) plans and/or care about his fate later in the game. There even seems to be a possible dialogue option to defend why you placed your trust in him that is something to the effect of, "but we've been friends since we were kids".
* ''VideoGame/{{Xenoblade}}'': Shulk, Reyn, and Fiora have all known each other since childhood, having grown up together in Colony 9. While Shulk and Reyn [[BashBrothers are best friends]], he developed [[ChildhoodFriendRomance romantic feelings towards Fiora.]] Which her older brother, Dunban, [[ShipperOnDeck heartily approves of.]]
* ''Franchise/TheLegendOfZelda'':
** The nature of Link's relation to Zelda varies with each game, with most portraying them as acquaintances, or simply comrades-in-arms. While in others, such as ''[[VideoGame/TheLegendOfZeldaTheMinishCap The Minish Cap]]'' and ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]'', they're cast as childhood friends with [[ChildhoodFriendRomance hints of a romance between them]].
** In ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'', Link grew up in Ordon Village with Mayor Bo's daughter, [[DoesNotLikeShoes Ilia]], and they're [[ImpliedLoveInterest heavily implied to have feelings for each other.]]
** In ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]'', Link was longtime friends with Mipha, the princess of the [[FishPeople Zora]] people, to the point that King Dorephan viewed Link as [[LikeASonToMe something of a son]]. Mipha [[ChildhoodFriendRomance fell in love with Link]], though whether Link felt mutually is not clear. It's also shown that Link was friends with most of the children in Zora's Domain, which is why none of the adults are hostile to him when he arrives post-Calamity.
* Aden and Sonja, the protagonists of ''[[VideoGame/RuneFactoryOceans Rune Factory: Tides of Destiny]]'', have been friends since birth.
* Endou and Kazemaru in ''VideoGame/InazumaEleven'', but it's never been disclosed how long exactly. Technically a number of the members of [[spoiler:Aliea]] and Little Gigant as well because they grew up together.
** In ''GO'', Tenma and Aoi. According to the latter's seiyuu Aoi has a crush on Tenma, but it has yet to be seen or hinted at.
** From ''GO'' as well, Amagi with Mahoro and Yukie. That is, before they fell apart when Mahoro started actively avoiding Amagi. [[spoiler:Naturally in this kind of series, they make amends.]]
* Garlot, Siskier, and Jenon in ''VideoGame/BlazeUnion''. Both Siskier and Jenon have got [[TriangRelations some sticky feelings that complicate things]], but for most of the game the three are nigh inseparable and their almost-familial friendship is an important source of emotional support for [[BrokenHero Garlot]].
* Ceodore and Ursula from ''VideoGame/FinalFantasyIVTheAfterYears''. Despite they reveal they are childhood friends, they seems only share only one scene together in the whole game. You do get to use their powerful [[CombinationAttack combination attack]], though.
* ''Franchise/KingdomHearts'' has Sora, Riku and Kairi. The first two have known each other their whole lives, while the latter arrives in their hometown when she's a kid and joins them.
* ''VideoGame/FinalFantasyXV'':
** Noctis and his gang. Ignis is said to be raised alongside Noctis in preparation for his job as advisor to the heir apparent when they're older, and Gladiolus comes from a family that traditionally has always been bodyguards to the kings of Lucis, implying that he has known Noctis from childhood as well. Despite the two technically being in Noctis' service, their bond is shown to be more brotherly than typical of a prince and his advisor and bodyguard. Noctis only meets Prompto in their teenage years, but he can easily be mistaken as a childhood friend as well, going by his interactions with the rest of the group.
** Noctis and Luna qualify as childhood friends as well, although possibly not as close, as they have been hinted to be estranged due to Niflheim's invasion of Tenebrae (Luna's hometown). However, WordOfGod has stated that the bond between Noctis and Luna is a basic plot element similar to the bond between Noctis and his gang, and likely just as important.
* Luke and Nick from ''VideoGame/TheWalkingDead'' have been close friends for at least 20 years.
* ''VideoGame/SkiesOfArcadia'': [[TomboyWithAGirlyStreak Aika]] was taken in by [[TheProtagonist Vyse's]] father when she was orphaned a child. She and Vyse have known each other at least since then, and have [[TrueCompanions an unshakable bond]], though they [[AvertedTrope avert]] the UsefulNotes/WestermarckEffect, as it's implied that Aika may have a crush on him.
* L'Arc with Alf and Adele in ''VideoGame/ArcRiseFantasia''.
* ''VideoGame/FireEmblemAwakening'':
** The pairs of Lissa/Maribelle and Sumia/Cordelia have been tight since they were young. This actually leads to Maribelle and Cordelia getting into a heated argument during the Summer Scramble DLC over which woman has the better BFF.
** Chrom and Sully were good friends and frequent sparring partners growing up. Sully respects Chrom, not only for his royal title and status as the leader of the Shepherds, but because Chrom was among a select few who could look past her gender and value Sully's skills unconditionally. As one of Chrom's scant number of potential marriage partners, the player can choose to wed Sully to him if they so desire.
** Chrom's Supports with Maribelle establish that they've also known each other since childhood, but this aspect of their relationship doesn't become prominent until [[RelationshipUpgrade their S Support]]. Given [[RomanticTwoGirlFriendship Maribelle's intimacy with Lissa]], Chrom's sister, this sets up [[ThreesomeSubtext a different dynamic between the three]], especially if the player opts to hold off on a Chrom/Maribelle S Support in favor of the post-Chapter [[spoiler:11]] confession scene.
** As the children of the Shepherds, all of the second generation units were raised together and thus are generally close, though not everyone shares the same level of affinity for another and some pairs are unable to interact outside of the Harvest and Hot-Spring Scrambles. However, a handful of the children (namely Kjelle, Severa, and Gerome) became increasingly more aloof as they aged, not helped by [[spoiler:living in a [[CrapsackWorld ruined]] [[BadFuture future]] and witnessing the deaths of their parents, some of whom they were not on the best of terms with]], and now keep their distance from certain individuals or the group as a whole until they eventually patch things up.
* ''VideoGame/FireEmblemFates'':
** Silas and the Avatar grew up together, but were separated when Silas was banished from the fortress where the Avatar was sequestered. Afterwards, Silas decided to become a knight, believing that the two would eventually be reunited someday. If the Avatar is female, the two of them can fall in love and get married. However, Silas cares incredibly deeply for the male Avatar as well, causing some speculation that Silas may have been intended as a same-sex romance (which [[{{Jossed}} later was disproved]] since there's no DummiedOut data regarding this in he game itself).
** Princess Sakura's retainers, Hana and Subaki, are childhood friends with Sakura's older siblings Takumi and Hinoka, respectively. The player can hook up Hana with Takumi and Subaki with Hinoka, if they wish.
** Laslow, Odin and Selena, who work for the Nohrian royal family, are three travelers who have been together ever since childhood. Again, the player can hook up Selena to either Laslow or Odin. [[spoiler:It's completely justified: they're actually Inigo, Severa and Owain from ''VideoGame/FireEmblemAwakening'', who were raised together alongside Lucina and the other Future Children before surviving a hellish BadFuture.]]
** Prince Ryoma's retainer Saizo and Queen Mikoto's subordinate Orochi met as young teens according to their supports, so if they don't get married they will be this.
** Downplayed slightly with Elise and her retainer Effie. They met in their youth when Elise snuck out of Castle Krakenburg to [[KingIncognito explore the city]] and quickly became good friends, but as Elise was forbidden from leaving the castle grounds without a chaperone following this incident, they didn't re-encounter one another for several more years, after Effie joined the royal knights and entered Elise's service. They still consider the other to be their best friend, and Effie is incredibly devoted to Elise.
* ''VideoGame/FireEmblemGaiden'' and its remake, ''VideoGame/FireEmblemEchoesShadowsOfValentia'':
** Alm and Celica has a ChildhoodFriendRomance going on, but this trope took place between the two and the Ram villagers Gray, Tobin and Kliff. ''Echoes'' not only adds Faye as Alm's [[ChildhoodFriendRomance Unlucky Childhood Friends]], but gives more focus to the bonds between Alm and the three village boys. Plus, if the player leaves Kliff and Faye at Ram, Celica can recruit them later and have them follow the trope with her instead.
** The CanonForeigner Fernand was friends with Clive, the SupportingLeader on Alm's side, from before Clive's sister Clair was born. The three have these dynamics, adding to the drama when Fernand [[spoiler: loses his family ''horribly'']] and ultimately has a FaceHeelTurn. [[spoiler: In the end, Fernand ends up fatally injured [[DiedInYourArmsTonight and passes away in Clive's arms]].]]
* ''Franchise/{{Pokemon}}'':
** [[PlayerCharacter Red]] and [[UsedToBeASweetKid Blue]] from ''VideoGame/PokemonRedAndBlue'' are [[WeUsedToBeFriends childhood friends gone rivals]], though by ''VideoGame/PokemonSunAndMoon'' they're back to being best friends.
** The opposite gender protagonist in ''[[VideoGame/PokemonGoldAndSilver Pokemon HeartGold and SoulSilver]]'' is presented as your longtime friend. They have some ShipTease with you as well.
** TheRival Barry from ''VideoGame/PokemonDiamondAndPearl'' is the player character's childhood friend. His father Palmer mentions this is GenerationXerox with Dawn's/Lucas' father.
** This also goes for [[VideoGame/PokemonBlackAndWhite Cheren, Bianca and the player]] and [[VideoGame/PokemonBlack2AndWhite2 Hugh and the player]] in Generation V.
* Max and Chloe from ''VideoGame/LifeIsStrange'' were best friends as kids. They lost touch when Max moved away when they were 13, but are reunited at the beginning of the game when Max comes back to town after five years.
* [[AntiHero Yuri]] [[BadassNormal Lowell]] and [[TheAce Flynn]] [[KnightInShiningArmour Scifo]] in ''VideoGame/TalesOfVesperia'' are this, having grown up in the [[UrbanSegregation Lower Quarter]] together and originally pursued the same dream in the knights before Yuri realized he couldn't do it. They are ''[[HoYay quite]]'' close even now despite their differing viewpoints and at times clashes.
* In ''VideoGame/TalesOfGraces'' Asbel, Hubert, Cheria, Richard, and Sophie are all this (with Asbel and Hubert also being brothers). A good chunk of the early drama comes from the fall out of [[spoiler:Sophie's HeroicSacrifice in the past]] that lead to them drifting apart.
* ''VideoGame/HarvestMoon'':
** Karen and Rick have been friends for years in ''VideoGame/HarvestMoon64''. ''VideoGame/HarvestMoonBackToNature'' has the two [[ChildhoodFriendRomance as a riva couple]].
** Played with in ''VideoGame/HarvestMoonAWonderfulLife''. Being two of the three only children in the entire town (with the third being initially a toddler), Hugh and Katie naturally gravitate towards each other. However, Katie is [[TheBully more of a bully than a friend]]. She becomes nicer as she ages and develops into Hugh's genuine friend.
* Several ''Franchise/SuperMarioBros'' games, such as ''VideoGame/YoshisIslandDS'' and ''VideoGame/MarioAndLuigiPartnersInTime'', show that Mario, Luigi, and Peach knew each others as toddlers. It's unclear whether they stayed friends throughout their lives or the twins moved away and the trio was reunited as adults.

[[folder:Visual Novels]]
* Kouin, Yuuto, Kaori and Kyouko of ''VisualNovel/EienNoAselia'' fall into this. Kaori doesn't have much of the dynamic, and Kyouko is more of a romance, but Kouin and Yuuto definitely fall into this. [[spoiler:The third chapter focuses around Kouin and Kyouko equally with the main plot of the entire world blowing up.]]
* Phoenix Wright, Miles Edgeworth, and Larry Butz from ''Franchise/AceAttorney''.
* ''VisualNovel/{{Tsukihime}}'':
** Arihiko and Shiki. Arihiko is one of the few people who really knows all about Shiki and understands him and the two are mostly inseparable.
** Shiki is also this with the maids Hisui and Kohaku. Also, Akiha except she is his sister even though [[{{NotBloodSiblings}} she's not really his sister]].
* Yoshiyuki, Wataru and Koko are all childhood friends in ''VisualNovel/DaCapoII''. Koko's relationship with the other two gets much more complicated, but Wataru and Yoshiyuki fall straight into this instead. It's one of the factors that makes Koko's route that much more dramatic.
* ''VisualNovel/TokimekiMemorial 2 Substories: Leaping School Festival'':
** An Event in Homura Akai's route reveals that [[spoiler: her grandfather Ringo and Hibikino High's headmaster Bakuretsuzan]] are childhood friends, and still are the best friends in the world despite [[spoiler: the years and the fact they were (friendly) rivals for the heart of the girl who would become Homura's grandmother, in their High School time]].
** And then there's Homura herself with Akane Ichimonji. The two are best friends since childhood, although Akane feels from time to time the need to take a break from Homura and avoids her, as shown in an Event in Childhood Mode. Speaking of Akane, in the 10th Drama CD, [[DiscussedTrope she and the protagonist, Kouichi, discuss about childhood friends]]:
-->'''Kouichi''': Say... Ichimonji-san, do you have someone you can call a childhood friend?
-->'''Akane''': Me? Mmm... Well, someone I could call as such... I'd say Homura.
-->'''Kouichi''': Aah, Akai-san, huh?
-->'''Akane''': Well, rather than a childhood friend, she's more like a ''kusare-en'' (a destined friend, a fatal bond) to me.
-->'''Kouichi''': I see.
-->'''Akane''': But, it's nice to have childhood friends.
-->'''Kouichi''': Is that so?
-->'''Akane''': They know each other very well, and can say everything to each other! They're like best friends, or even family!
* The original eponymous ''VisualNovel/LittleBusters'' were made up of five childhood friends, four guys and one girl.
* Hiroki and Yanagi in ''VisualNovel/{{Canvas 2}}''. [[spoiler:A later event in the story is about an attempt to repair said friendship due to some complications involving the third childhood friend that they both liked.]]
* In ''VisualNovel/MajiDeWatashiNiKoiShinasai'' we have both the Kazama Family including seven people, and the 2-S trio of Touma, Jun, and Koyuki.
* Yuuchi from ''VisualNovel/{{Kanon}}'' has childhood friendship relationships with all female main characters, except Shiori.
* Ryouta and Hiyoko, in ''VisualNovel/HatofulBoyfriend''. Ryouta even gets anxious and possessive when considering the idea that Hiyoko may grow apart from him in time.
* This is Mayuri's and Okabe's relationship in ''VisualNovel/SteinsGate''. While they care deeply for each other (to the point that Okabe [[spoiler:nearly kills himself by repeatedly time jumping trying to avert her death]]), there's practically no sexual tension between them, and they never speak of each other in romantic terms. If asked, they will refer to Mayuri as Okabe's "hostage", a sort of in-joke reference to one of his MadScientist rants when they were younger.
* The girls in ''VisualNovel/MyHaremHeavenIsYandereHell'' are this to Yuuya. Since this is a {{Yandere}} RomanceGame, things will go downhill.
* Subaru and Saki are this in ''VisualNovel/YandereILoveYouSoIWantToKillYou''. Subaru takes advantage of her already established feelings and gets her to have sex with him.
* Sonono Nene and Ootori Reina from [=ClockUp=]'s Team Anise's ''Eroge! Sex and Games Make Sexy Games''. At first glance, [[NotHyperbole you would think that the former is the latter's daughter]] (Tomoya even mentions it at one point)...but they're ''both'' '''[[OlderThanTheyLook in their thirties.]]''' Yipes.
* Junpei and Akane from ''VisualNovel/NineHoursNinePersonsNineDoors'' went to elementary school together and haven't seen each other since then. Now they have to survive the Nonary Game with seven more people, nine years later.
* In ''VideoGame/ShallWeDateNinjaShadow'', it turns out that Eduard has been living in Ukyo's village ever since he was a child, so he and a guy named Natsume (from a game named ''VideoGame/ShallWeDateNinjaAssassin'') have been close ever since childhood.

[[folder:Web Comics]]
* Penny, Sara and Michelle of ''Webcomic/PennyAndAggie'' have been friends since their preteen years, Penny and Sara for at least two years longer. WordOfGod also has it that [[TheBeard Fred and Daphne]] have been best friends since childhood.
* ''Webcomic/TowerOfGod'':
** Beniamo Cassano and Beniamo Ilmar (now known as Kang Horyang), two boys who grew up together as scientific experiments.
** Also, Baam and Rachel, but their relationship was always kinda complicated.
* ''Webcomic/PrinceOfCats'': Lee and Frank met in second grade and have been inseparable ever since.
* ''WebComic/VampireCheerleaders'' features a {{crossover}} childhood friendship between Stephanie Kane (the protagonist of ''WebComic/ParanormalMysterySquad'') and Layla Delacroix (from ''WebComic/EerieCuties''). Which came about as a result of AscendedFanon, since both have emotive skull hairpins. As it turns out, it was coincidental, but Adam Arnold (the author of ''PMS'') collaborated with Giselle Legace and David Lumsdon (the co-writers of ''Eerie Cuties'' and ''WebComic/MagickChicks'') and made it so Layla had a matching set of hairpins as a child and had [[http://www.eeriecuties.com/strips-ec/treasure_it_always_-_guest_strip given one to Stephanie as a parting gift.]]
* Georgia, Rita, Ean, Siggi and Jen in ''Webcomic/FineSometimesRain'' grew up together and have been close friends since childhood.
* Rain and Gavin in ''Webcomic/{{Rain}}'', although there were several years between their initial friendship and subsequent reunion, during which Rain quietly transitioned. Gavin remembers Rain as a boy named Ryan.

[[folder:Web Original]]
* In ''WebAnimation/TheMostPopularGirlsInSchool'', a number of the main and recurring cast have known each other since the Third Grade, or for some, earlier than that. It would be much more appropriate to say that some pairs are Childhood VitriolicBestBuds. Of course, it would be a total mistake to call Shay and Mackenzie friends.
* Gaea and Golgotha in ''Franchise/{{Noob}}''. Gaea may have since become a DirtyCoward [[ConMan Con Woman]], but you'll have to deal with quite the [[BigBrotherInstinct Big Sister Instinct]] if you dare lay a hand on her while [[BloodKnight Golgotha]] is online.
* ''WebAnimation/{{RWBY}}'': Ren and Nora start the show as seventeen year olds and have already been together for a very long time. Nora is concerned about making sure they are teamed together in class, even inventing secret "sloth" call noises that Ren is certain cannot be a real sloth's sound. Ren tries to rein in Nora's hyperactivity and wild enthusiasm while Nora thinks his penchant for "health" drinks leaves something to be desired. Nora admits they're orphans with no home outside Beacon Academy in a throw-away comment to others, and they are so close that others erroneously think they're in a romantic relationship. Nora is secretly in love with Ren, but has no idea whether he feels the same way.

[[folder:Western Animation]]
* The main cast in ''WesternAnimation/AllGrownUp'', for it is a sequel series to ''WesternAnimation/{{Rugrats}}''.
* The majority of the third-grade cast of ''WesternAnimation/{{Arthur}}'' have known each other since preschool.
* Flashbacks show that WesternAnimation/BeavisAndButtHead have always been the same since they were kids.
* Wendy and Tambry from ''WesternAnimation/GravityFalls'' have been friends since they were five.
* It's revealed in ''WesternAnimation/{{Grojband}}'' that Trina and Mina have known each other since kindergarten.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', this is the main reason [[HotBlooded Rainbow]] [[JerkWithAheartOfGold Dash]] and [[ShrinkingViolet Flutter]][[FriendToAllLivingThings shy]] are so close. They both went to flight camp together, and Dash was happy to defend Fluttershy from the bullies who would pick on her. Exactly ''how well'' they knew each other as kids [[DependingOnTheWriter depends on the writer]]. The first two seasons had episodes that implied Rainbow knew next to nothing about her and Fluttershy failing to recognize one of Rainbow's old friends. Meanwhile, later seasons make it clear that they were close enough as kids to know the odd quirks of the other's families.
* ''WesternAnimation/{{Motorcity}}''. [[AllThereInTheManual According to the Motorcity bible, Julie and Claire]] (who appear to be this their mid-to-late teens) have been best friends since kindergarten.
* Candace and Stacy in ''WesternAnimation/PhineasAndFerb''. They have shared an enduring friend relationship. It is unknown when they met or how they became friends. What is known is that their relationship can be traced as far back as the third grade, when they were trying to impress a boy named Billy Clarke.
* In ''WesternAnimation/{{Sixteen}}'', the main cast (minus Caitlin) have been friends since Kindergarten.
* The four boys of ''WesternAnimation/SouthPark'' have known each other since preschool... and even back then, Kyle and Cartman were VitriolicBestBuds.
* ''WesternAnimation/SuperNoobs'':
** This show has a group of them as main characters, consisting of Tyler, Kevin, Roach, and Shope, who are better off known as the "Noobs" and have obviously been hanging out with each other since they did not have any other friends until they became virus warriors
** Memnock and Zenblock, the Noobs' alien tutors, heavily imply in "Zooper Noobs" that they have known each other ever since they were children as they both mentioned that they loved riding the monorail at the space zoo when they were kids, making it very likely that they either went there together or first met at the space zoo.
* ''WesternAnimation/TotalDrama'': First season contestants Katie and Sadie not only stated that they knew each other since they were kids, but were next door neighbors for their entire lives and that they got the chickenpox together. Their bond is shown to be very strong and inseparable because of this and could survive a lot of bickering bouts.
* ''WesternAnimation/TheRidonculousRace'':
** Racing partners, Carrie and Devin have stated that they first met at a sandbox when they were kids and have been friends ever since. Their relationship soon turned romantic over the course of the race.
** Ice Dancers Jacques and Josee state in the Brazil leg of the race that they have been making great costumes since they were kids and that they have known each other for fourteen years. Taking into account, the WordOfGod statement that Jacques is 22 and Josee is 20, its made clear that they have first met when Jacques was 8 years old and when Josee was 6 years old.
