What's New, Scooby-Doo? is the ninth incarnation of the Hanna-Barbera Saturday morning cartoon franchise Scooby-Doo. A revival of the original Scooby-Doo, Where Are You! after a decade-long gap in a new Scooby television show, it debuted in 2002. The series was developed and produced by Warner Bros. Animation and originally aired as part of the Kids' WB Saturday morning block on The WB Television Network. The Canadian punk band Simple Plan performs the theme song.

Reruns currently air on Boomerang in the United States, Teletoon in Canada, and CITV, Boomerang and Cartoon Network in the United Kingdom. What's New was the first Scooby-Doo series to feature Mindy Cohn and Grey DeLisle as the voices of Velma and Daphne respectively, the first where Frank Welker voiced Scooby, and the last to feature Casey Kasem as the voice of Shaggy.
