Kingdom Hearts III is an upcoming action role-playing video game developed and published by Square Enix for the PlayStation 4 and Xbox One. It is the twelfth installment in the Kingdom Hearts series, a sequel to Kingdom Hearts II, and the final chapter in the Dark Seeker saga. Set after the events of Kingdom Hearts 3D: Dream Drop Distance, returning protagonist Sora is joined by Donald Duck, Goofy, King Mickey and Riku in their search for the seven Guardians of Light and the "Key to Return Hearts" as they attempt to thwart Master Xehanort's plan to bring about a second Keyblade War. Their journey has them cross paths with characters and visit worlds based on different Disney, and Pixar properties, and Square Enix's Final Fantasy franchise.

Concepts for the game began as early as 2006 after the release of Kingdom Hearts II: Final Mix in Japan, with the game not confirmed to be in development until E3 2013 after years of rumors and speculation. Kingdom Hearts III sees many returning gameplay features from the series, while expanding parties to five characters total, introducing new "Attraction Flow" attacks that incorporate various Disney Parks attractions, and mini-games inspired by classic Walt Disney Productions Mickey Mouse cartoons in the style of 1980s LCD games. The game was built using Unreal Engine 4, and is scheduled to be released worldwide in January 2019.
