Shiro Amano's manga adaptation of the [[VideoGame/KingdomHeartsI popular video game]]. Focuses more on comedy, though. It was originally released in four volumes (which was translated into English by {{Creator/Tokyopop}}), then the ''Final Mix'' version came out, and became three. As of 2013, the ''Final Mix'' version is available in English, re-translated by Creator/YenPress and released completely in two volumes.

Unlike the manga adaptations for the other games, ''Kingdom Hearts'' is read from left-to-right, as per Western tradition.

!!This manga contains examples of:

* BreakingTheFourthWall:
** Once Cerberus goes down, Hercules gives the reader an AsideGlance and tells them he'd already worn Cerberus down by the time Sora dropped by to help.[[note]]He said this in the game too, but to Phil rather than through the fourth wall.[[/note]]
** When Captain Hook and his crew are losing to the heroes, Smee pulls a ScrewThisImOuttaHere. He turns to the reader and says they'll understand why he's doing this[[note]]In the Yen Press translation, he simply tells the [[/note]].
* ButtMonkey: Donald Duck. For instance, while Sora and Goofy eventually manage to fly after being sprinkled with fairy dust, Donald falls every time.
* TheCameo: Olympus Colesseum's tournaments don't get so much as a mention, but Hades fantasises about letting the Titans out of the Underworld using the Keyblade and they briefly appear during his ImagineSpot.
* CaptainCrash: Sora's first time as pilot results in him ramming the Gummi Ship into a Meteor near Traverse Town. Donald is completely livid and forbids him from ever piloting it again. [[spoiler: Sora does not [[Manga/KingdomHeartsII listen]] to him...]]
* ChekhovsGun: One of the "title screen" pages for [[Disney/{{Aladdin}} Agrabah]] shows Sora wearing a turban (and it looks very nice on him). Guess what he wears when pretending to be a genie in the [[VideoGame/KingdomHeartsChainOfMemories next game's]] [[Manga/KingdomHeartsChainOfMemories manga adaption]]...
* ChuckCunninghamSyndrome: Halloween Town makes no appearance at all in the manga, despite its massive popularity[[note]]Deep Jungle also makes no appearance, due to losing the rights by the time the manga was released[[/note]].
** Strangely however, some of Oogie Boogie's dialog from the Disney villain councils' introduction is kept anyway (his "you're no prize yourself!" quip).
* EarlyBirdCameo: [[spoiler: Roxas]] makes a cameo appearance in the ''Final Mix'' translation's bonus chapter, which is based on "Another Side, Another Story".
* EstablishingCharacterMoment: A Soldier Heartless attacking and stealing the heart of a woman in Traverse Town lets you in on their nature.
* GettingCrapPastTheRadar:
** Sora gets hit on by a prostitute, despite his young age, which makes him really nervous.
** Sora going through Ariel's collection, which his friends called him out on!
* GoForTheEye: Sora calls on ''Battle of the Bengal Tiger'' while fighting Darkside. This is a frequent tactic with giant enemies in the actual games.
* HappinessIsMandatory: You gotta smile at all time, as it is the fuel for the Gummi Ship.
* LampshadeHanging: The irony of having a hard time flying despite being a bird does not escape Donald.
-->'''Donald:''' (while [[AsideGlance looking directly at the reader]]) Come on! I'm a ''duck!''
* LighterAndSofter: Than the game version, but still contains some NightmareFuel.
* OhWaitThisIsMyGroceryList: Some of the volumes included a set of one-shot comic strips at the end of the volume, generally featuring an amusing twist on something that happened in the main story. One of the ones at the end of the original Volume 3 featured Aerith trying to decode Ansem's [[spoiler:Xehanort's]] Report. "Ansem the Wise... what were you trying to do...? Pork, onion, carrot, potato, shiitake mushroom... Ansem... You like shiitake mushroom in your curry?!"
* ShipTease: The front cover for chapter 31 ("A Storm, Love, and a New Beginning") ships Sora and [[Disney/TheLittleMermaid Ariel]] together.
* YouHaveOutlivedYourUsefulness: Riku-[[spoiler:Ansem]] stabs Maleficent with the Keyblade created from the Princesses of Heart, but she dies rather than turn into her [[OneWingedAngel dragon form]].
