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 Pixar's Toy Story franchise. The film was directed by John Lasseter from a screenplay by Andrew Stanton, Rita Hsiao, Doug Chamberlin, and Chris Webb. 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 Toy Story film, with newcomers Joan Cusack, Kelsey Grammer, Wayne Knight, Estelle Harris, and Jodi Benson joining the cast. 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 premiered at the El Capitan Theatre on November 13, 1999, and was released on November 24 to box office success, grossing $511 million against a $90 million budget. It received widespread acclaim from critics, 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. Among its accolades, the film won Best Motion Picture – Musical or Comedy at the 57th Golden Globe Awards. A further sequel, Toy Story 3, was released in 2010.

Woody and Buzz Lightyear have become co-leaders of Andy's toys. Andy plans to take Woody to Cowboy Camp, but accidentally rips his arm. Andy's mother places Woody on a shelf, and Woody begins to fear that Andy will throw him away. The following day, Woody finds Wheezy, a penguin toy with a broken squeaker, who has also been shelved. After saving Wheezy from being sold at a yard sale, Woody is found and stolen by a greedy toy collector. Buzz fails to foil the theft, but finds clues identifying the collector as Al McWhiggin, the owner of the Al's Toy Barn store. Buzz, Mr. Potato Head, Slinky Dog, Rex, and Hamm set out to rescue Woody.

At Al's apartment, Woody discovers that he was designed after the protagonist of Woody's Roundup, a popular 1950s children's Western series, and meets his co-star character dolls: Jessie the Cowgirl, Bullseye the Horse, and Stinky Pete the Prospector. While delighted to meet them, Woody realizes that Al plans to sell the entire Woody's Roundup collection to a toy museum in Tokyo. Woody announces that he has to return home to Andy, dismaying the gang, because the museum will not accept the collection without him, and they will go back into storage. After Woody's arm is repaired the next day, Woody learns that Jessie was abandoned by her owner, Emily, when she grew up. Convinced that Andy might do the same to him, Woody decides to go to the museum.

Meanwhile, Buzz's group reaches Al's Toy Barn and searches for Woody. Buzz encounters a Utility Belt Buzz toy; assuming he is a real space ranger going AWOL, Utility Belt Buzz imprisons Andy's Buzz. Utility Belt Buzz later meets Andy's other toys and, assuming they are on a mission to defeat his arch-nemesis, Emperor Zurg, accompanies them to Al's apartment. Andy's Buzz escapes and follows the gang, inadvertently releasing a toy Zurg who follows Buzz to destroy him.

Both Buzzes and the rest of the search party arrive at the apartment, but Woody refuses to go home with them. Shortly after the search party leaves, Woody reconsiders and invites the Woody's Roundup toys to join him and become Andy's toys. While a hesitant Jessie and an enthusiastic Bullseye accept Woody's offer, Pete refuses and blocks the others from leaving; having never been played with, he is adamant about going to the museum.

Al returns to the apartment and takes the Woody's Roundup collection to the airport. On the elevator ride down, Zurg appears and fights Utility Belt Buzz until he is knocked off the elevator by Rex. The two end up reconciling after Buzz learns Zurg is his father, while Andy's Buzz and the other toys pursue Al to the airport in a Pizza Planet truck while being accompanied by three toy aliens. Following a prolonged pursuit through the airport's baggage sorting system—during which Pete re-opens the tear in Woody's arm—the other toys subdue Pete and place him in the backpack of a little girl, who takes Pete with her. They save Bullseye, but Jessie is loaded onto the plane. Woody, Buzz, and Bullseye work together to save her just as the plane takes off. The toys then return home to Andy's house.
