All Purpose Cultural Cat Girl Nuku Nuku (万能文化猫娘 Bannō Bunka Nekomusume) is a six-episode anime OVA created in 1992.

It spawned a 12-episode anime TV series remake (of the same name) in 1998, as well as a 12-episode second OVA series All Purpose Cultural Cat Girl Nuku Nuku Dash in that year. They are based on an original short manga by Yuzo Takada (3x3 Eyes, Blue Seed). The series also has a manga adaptations.

In the show, genius inventor Kyusaku Natsume transplants the brain of his son Ryunosuke's cat into a schoolgirl android that he created and subsequently stole from his former employer, Mishima Heavy Industries (owned by his ex-wife and Ryunosuke's mother, Akiko Mishima). The result, Cat Girl Nuku Nuku (a.k.a. Atsuko Natsume), is a nekomusume (猫娘) or cat girl.

Plot generally centers around the custody battle for Ryunosuke and the attempts by Akiko and Mishima Heavy Industries to reclaim Nuku Nuku's body. This often involves amusingly larger-than-life battles between Nuku Nuku and military hardware produced by Mishima Heavy Industries.

All three incarnations feature renowned Japanese seiyū Megumi Hayashibara (as Nuku Nuku) and Aya Hisakawa (as Mishima Heavy Industries employee Arisa).

All three are available on DVD in the United States, distributed by ADV Films. A dubbed version of the OVA was previously available in the United Kingdom on VHS featuring regional accents, but is long out of print.

The manga is published in English by ADV Manga.
