Kingdom Hearts is a 2002 action role-playing video game developed by Square for the PlayStation 2 video game console. It is the first game in the Kingdom Hearts series and is the result of a collaboration between Square and The Walt Disney Company.

The game combines characters and settings from Disney animated features with those from Square's Final Fantasy series, in addition to original characters and worlds created for the game. It follows the adventures of Sora, a cheerful teenager who fights against the forces of darkness alongside Donald Duck, Goofy and other Disney characters. The game was a departure from Square's standard role-playing games, introducing a substantial action and hack and slash element to the gameplay.
