Lilo & Stitch: The Series (titled simply as Disney's Lilo & Stitch on its title card and on U.S. copyright registrations) is an American animated television series produced by Walt Disney Television Animation. It premiered on September 20, 2003, on ABC as part of ABC Kids, with a delayed premiere on Disney Channel on October 12, 2003. The series ended on July 29, 2006, after airing 65 episodes in two seasons.

A sequel spin-off of the 2002 feature film of the same name on which it was based, and the follow-up to August 2003 direct-to-video pilot Stitch! The Movie, it was the first of three television series produced in the Lilo & Stitch franchise, and the only one to retain the same setting as the original film. It aired on Disney Channel worldwide but has only been released on DVD in full in Japan, in four box sets. On November 12, 2019, the series was made available to stream on Disney+, immediately following the service's launch.
