Scooby-Doo! and the Goblin King is a 2008 direct-to-DVD animated comedy horror musical film, and the twelfth in the series of Scooby-Doo direct-to-video films produced by Warner Bros. Animation (though it used a Hanna-Barbera logo at the end of the film). It was dedicated to Paulette Oates, who helped resurrect Warner Bros. Animation in the late 1980s. The DVD was released on September 23, 2008. This is the first Scooby cartoon produced entirely without either one of the original producers, William Hanna and Joseph Barbera.

This film calls back to the shared premise of The Boo Brothers, The Ghoul School, and The Reluctant Werewolf films from the late 1980s, where the fantastical elements of the story are genuine, and Scooby and Shaggy alone discover and befriend an entire society of supernatural beings.
