Scooby-Doo on Zombie Island is a 1998 animated direct-to-video horror-comedy film based on the animated television series Scooby-Doo Saturday morning cartoon franchise. In the film, Scooby-Doo, Shaggy, Velma, Daphne and Fred reunite to solve a frightening new mystery: they leave for a haunted bayou island to investigate the ghost of Morgan Moonscar the Pirate. It is the first in a long-running series of direct-to-video Scooby-Doo films; succeeded by Scooby-Doo and the Witch's Ghost (1999). Production started at Hanna-Barbera, but was then completed by its then-new parent company, Warner Bros. Animation (which would produce all subsequent Scooby-Doo films). It was also the first of four Scooby-Doo direct-to-video films to be animated overseas by Japanese animation studio Mook Animation.
