Buzz Lightyear of Star Command is an American animated science fiction comedy television series produced by Walt Disney Television Animation and co-produced by Pixar Animation Studios. It serves as a spin-off of the Toy Story franchise and presents a fictionalized account of the in-universe character Buzz Lightyear. The series was preceded by the direct-to-video film Buzz Lightyear of Star Command: The Adventure Begins, and aired on UPN and ABC from October 2, 2000, to January 13, 2001, as part of Disney's One Saturday Morning and Disney's One Too programming blocks. While the series is 2D animated, Pixar animated the CGI opening title sequence at the beginning of each episode. The program was animated by Walt Disney Animation Japan, Tama Productions, Sunwoo Entertainment, Sunmin Image Pictures, Sae Hahn Productions, Hana Animation, Jade Animation, Wang Film Productions and Toon City.

Developed by Bob Schooley and Mark McCorkle, who would later create Kim Possible for Disney Channel, the series follows the adventures of Space Ranger Buzz Lightyear. The character first appeared as an action figure (voiced by Tim Allen) in the 1995 film Toy Story. Patrick Warburton voices the character in the television series. A video game of the same name based on the series was released in 2000. An unrelated animated feature film fully produced by Pixar, Lightyear, was released in 2022, serving as an origin story for the character, voiced by Chris Evans.

This was the last Toy Story production for nearly a decade until the release of Toy Story 3 in 2010.
