Genocyber: The Beauty Devil from Psychic World (ジェノサイバー虚界の魔獣, Jenosaibā: Kyōkai no Majū, lit. "Genocyber: A Cyber Monster from the Imaginary World") is a 1992 Japanese manga series by Tony Takezaki. One volume of the manga has been published, but the multi-volume story arc remains unfinished. The published book was adapted by Koichi Ohata into a five-part original video animation (OVA) series in 1994. The plot of the anime differs significantly from the manga. Both are notable for their extreme graphic violence.

The OVA was produced by Bandai Visual and released in North America by U.S. Manga Corps. Genocyber was also released by Manga Entertainment's UK and Australian Divisions in The Cyberpunk Collection but only episodes 1-3 were released in these regions; this collection also included two other cyberpunk OVAs, Cyber City Oedo 808 and A.D. Police Files. The remaining two parts were not released into English until U.S. Manga Corp obtained the rights and had Central Park Media dub the remaining two episodes that were not dubbed by Manga UK.

In September 2020, Discotek Media announced they have acquired the distribution rights to Genocyber.
