Scooby-Doo is an American cartoon series based around several animated television series and related works produced from 1969 to the present day.

Some versions of Scooby-Doo feature different variations on the show's supernatural theme, and include characters such as Scooby's cousin Scooby-Dum and nephew Scrappy-Doo in addition to or instead of some of the original characters.
