Win or Lose is an American animated television miniseries produced by Pixar Animation Studios for the streaming service Disney+ and is the first original series from the studio. It was created and written by Carrie Hobson and Michael Yates, who also served as executive producers with David Lally, Pete Docter, Andrew Stanton, and Lindsey Collins. The series revolves around a co-ed softball team at middle school named the Pickles in the week leading up to their big championship game, with each episode showing the perspective of each member in the same events, each reflected in a unique visual style.

The series' cast includes Will Forte, Ian Chen, Izaac Wang, Jo Firestone, Milan Ray, Josh Thomson, Erin Keif, Rosie Foss, Rosa Salazar, Chanel Stewart, Dorien Watson, Lil Rel Howery, Flula Borg, Kyliegh Curran, Jaylin Fletcher, Tom Law, Beck Nolan, Orion Tran, and Rhea Seehorn. Pixar was developing the long-form original series following the creation of Disney+. It was officially announced in December 2020, during Disney's Investor Day, with Hobson and Yates on board who conceived the idea. Win or Lose draws inspiration from the conversations between Hobson and Yates, who would have very different reactions to the exact same events upon working on Toy Story 4 (2019). The animation style appears to shift, distinguishing itself further in each episode, with Brendan Beesley, Brandon Kern, and Tom Zach as the heads of animation. Docter described the series as "a comedy about love, rivalry, and the challenges we all face in our struggles to win at life". Its musical score was composed by Ramin Djawadi.

Win or Lose premiered on Disney+ on February 19, 2025, and consisted of eight episodes releasing weekly in groups of two until March 12. It received positive reviews from critics, although Disney's decision to remove scenes explicitly confirming a character as being transgender was criticized.
