GeGeGe no Kitarō (ゲゲゲの鬼太郎^?) is a manga series created in 1960 by Shigeru Mizuki. It is best known for its popularization of the folklore creatures known as yōkai, a class of spirit-monster to which all of the main characters belong. It has been adapted for the screen several times, as anime, live action and video games. A new anime series has been made every decade since 1968.

The title of the original story is Hakaba no Kitarō (墓場の鬼太郎^?), literally meaning "Kitarō (of the) Graveyard". This story was an early 20th-century Japanese folk tale performed on kamishibai. The name "Ge Ge Ge..." was applied to Mizuki's particular telling of the Kitarō story when a Toei Animation series based on the characters of his comic was created. In January, 2008, the original comic was finally adapted into an animated series, running in Fuji TV's Noitamina slot.
