Kitbull is a 2019 American animated buddy-drama short film and viral video written and directed by Rosana Sullivan, produced by Pixar Animation Studios, and distributed by Walt Disney Studios Motion Pictures. It is the third film in Pixar's SparkShorts program, and focuses on a fiercely independent stray kitten and an abused pit bull, who form an unlikely friendship. The short premiered at El Capitan Theatre on January 18, 2019, before being released on YouTube on February 18, 2019, and has received over 100 million views as of August 2023. The short was also released on Disney+ on November 12, 2019 and was later released in theaters on February 9, 2024 ahead of Turning Red.

Sullivan said that the creation of the short had originated from her enjoyment of viewing cat videos, and Hendrickson stated that the traditional animation had proved to be challenging in the beginning. Critical reception of the short has been generally positive, with critics praising its story, emotional tone, themes, characterization, and animation. The short was nominated for the Academy Award for Best Animated Short Film at the 92nd Academy Awards. In 2019, Pixar stated there were no plans to release a DVD including the film or any sequel to it.
