Night of the Living Doo is an American animated television special that aired on Cartoon Network on October 31, 2001. The cartoon is a comedic parody of a typical episode of The New Scooby-Doo Movies, complete with unlikely guests and a retro style. Its title is a riff on the Night of the Living Dead franchise. The animation was produced by Cartoon Network and broadcast in small segments during commercial breaks of a Halloween Scooby-Doo marathon. At the end of the marathon, the complete special was broadcast in its entirety and was available on the Adult Swim website for a brief period. It has not been released on home video.

The special features a new opening title sequence combining the opening for The New Scooby-Doo Movies with clips of the special, set to the cover of the Scooby-Doo, Where Are You! theme song as performed by Matthew Sweet for Saturday Morning: Cartoons' Greatest Hits. It was nominated for an Annie Award.

In this special the characters are animated in a classic retro style in an effort to parody real episodes. The show is meant to have the 60s feel with modern humor and celebrities. Most of the scenes have the gang's animation directly rotoscoped from certain classic episodes, in some cases even completely re-dubbed footage.
