Toy Story is a computer animated film series and Disney media franchise that began with the 1995 film of the same name, produced by Pixar Animation Studios and released by Walt Disney Pictures. The franchise is based on the anthropomorphic concept that all toys, unknown to humans, are secretly alive, and the films focus on a diverse group of toys that feature a classic cowboy named Sheriff Woody and a modern spaceman named Buzz Lightyear. The group unexpectedly embark on adventures that challenge and change them.

The first two films of the franchise were directed by John Lasseter, and the third by Lee Unkrich, who acted as the co director of the second film (together with Lasseter and Ash Brannon). Josh Cooley will direct the upcoming fourth film.

All three films, produced on a total budget of $320 million, have grossed more than $1.9 billion worldwide. Each film set box office records, with the third included in the top 15 all time worldwide films. Critics have given all three films extremely positive reviews. Special Blu ray and DVD editions of Toy Story and Toy Story 2 were released on March 23, 2010. They were also re-released in theaters as a Disney Digital 3-D "double feature" for at least two weeks in October 2009.

The series is the 24th highest-grossing franchise worldwide, the fifth highest-grossing animated franchise (behind Shrek, Despicable Me, Ice Age, and Madagascar) and is among the most critically acclaimed trilogies of all time. On November 1, 2011, all three Toy Story films were released in Disney Blu-ray 3D as a trilogy pack and as individual films.
