Toy Story 3 (also known as Toy Story 3: The Video Game) is a platform game developed by Avalanche Software and published by Disney Interactive Studios. It is loosely based on the 2010 film of the same name. It was released in June 2010 for PlayStation 3, Xbox 360, Wii, Windows, and Mac OS X. A Nintendo DS version was developed by n-Space, while Disney Mobile Studios developed and published an iOS game based on the film. Another version was developed by Asobo Studio and released for PlayStation 2 and PlayStation Portable.

By February 2008, Disney and Pixar had rejected THQ's pitch to develop the film's video game adaptation, choosing instead to have it developed by Disney's Avalanche Software. A 10-person team from Pixar aided Avalanche in developing the game. Most of the voice cast from the film reprised their characters for the game. Toy Story 3 includes a story mode that loosely recreates the film's events, and the Toy Box mode, consisting of a western town that can be freely roamed and customized by the player. The game was well received by critics, particularly for its Toy Box mode. The game was a top-seller in the UK.
