Android Kikaider: The Animation (人造人間キカイダー THE ANIMATION, Jinzō Ningen Kikaidā Ji Animēshon?), the anime adaptation of the Japanese superhero Kikaider, was produced by Sony Animation and broadcast on Kids Station from October 16, 2000 to January 8, 2001, with a total of 13 episodes.

It was followed by the OVA 4-episode sequel, Kikaider 01: The Animation (キカイダー０１ THE ANIMATION, Kikaidā Zero Wan Ji Animēshon?).

The Anime followed more of the manga, with a darker nature of Jiro's reason to exist. It was followed by said 4-episode OVA series, which was the finale. Afterwards, there was also an OVA special which teamed Kikaider with Inazuman, another classic manga/tokusatsu superhero created by Shotaro Ishinomori (This latter special has yet to be seen in America).
