PB&J Otter is an American animated musical children's television series that aired on Disney Channel's preschool block Playhouse Disney from March 14, 1998 to October 23, 2000. The series centers on the Otter family, who live in the rural fishing community of Lake Hoohaw. Most stories revolve around the three Otter kids: older brother Peanut, younger sister Jelly, and baby sister Butter (named after the peanut butter and jelly sandwich), as well as their friends and neighbors.

The series was created by Jim Jinkins, who also created Doug and Allegra's Window, and executive-produced by David Campbell in close conjunction with Harvard University's Cognitive Skills Group, "Project Zero". The group's job was to monitor each and make sure the material had a positive educational message. The series features songs by Dan Sawyer, Fred Newman and Rich Mendoza. 65 episodes were produced.

In 2000, PB&J Otter was nominated for an Annie Award for "Outstanding Music in an Animated Series".
