Toy Story 2 is a 1999 American animated adventure comedy film produced by Pixar Animation Studios for Walt Disney Pictures. It is the sequel to Toy Story (1995) and the second installment in the Toy Story franchise. The film was directed by John Lasseter, co-directed by Ash Brannon and Lee Unkrich, and produced by Helene Plotkin and Karen Robert Jackson, from a screenplay written by Andrew Stanton, Rita Hsiao, Doug Chamberlin, and Chris Webb, and a story conceived by Lasseter, Stanton, Brannon, and Pete Docter. Tom Hanks, Tim Allen, Don Rickles, Jim Varney, Wallace Shawn, John Ratzenberger, Annie Potts, R. Lee Ermey, John Morris, Laurie Metcalf and Jeff Pidgeon reprise their roles from the first film. In the film, Woody is stolen by a greedy toy collector, prompting Buzz Lightyear and his friends to save him, but Woody is then tempted by the idea of immortality in a museum.

Disney initially envisioned Toy Story 2 as a direct-to-video sequel. The film began production in a building separated from Pixar, on a small scale, as most of the main Pixar staff were busy working on A Bug's Life (1998). When story reels proved promising, Disney upgraded the film to a theatrical release, but Pixar was unhappy with the film's quality. Lasseter and the story team redeveloped the entire plot in one weekend. Although most Pixar features take years to develop, the established release date could not be moved and the production schedule for Toy Story 2 was compressed into nine months.

Despite production struggles, Toy Story 2 debuted on November 24, 1999, to a successful box office run, eventually grossing over $511 million. It received widespread acclaim from critics and audiences, with a 100% rating on the website Rotten Tomatoes, similar to its predecessor. It is considered by critics to be one of the few sequel films superior to the original and is frequently featured on lists of the greatest animated films ever made. Toy Story 2 would go on to become the third-highest-grossing film of 1999, behind Star Wars: Episode I – The Phantom Menace and The Sixth Sense. Among its accolades, the film won Best Motion Picture – Musical or Comedy at the 57th Golden Globe Awards. The film has seen multiple home media releases and a theatrical 3D re-release in 2009 as part of a double feature with the first film, 10 years after its initial release. Two sequels have been released: Toy Story 3 (2010) and Toy Story 4 (2019).
