Gainax Company, Limited is a Japanese anime studio most well known for the series Neon Genesis Evangelion and its ambitious, experimental works and ambiguous endings.

Until Neon Genesis Evangelion, Gainax typically worked on stories created in-house, but the studio has increasingly developed anime adaptations of existing manga like Kareshi Kanojo no Jijou and Mahoromatic. Gainax could be said to produce two types of anime today: commercial works like Mahoromatic and He is My Master versus more experimental works that follow the company's traditions, such as FLCL and Diebuster. In addition to anime production, Gainax heavily merchandises its famous properties. For example, even though Evangelion ended in 1996, games, t-shirts, and various other memorabilia are still being produced.

Anime created by Gainax that have won the Animage Anime Grand Prix award have been Nadia: The Secret of Blue Water in 1991, Neon Genesis Evangelion in 1995 and 1996, and The End of Evangelion in 1997.

Gainax has also produced a number of computer games, including a strip mahjong game featuring Evangelion characters, and its most famous games, the Princess Maker series, which was later adapted as Puchi Puri Yūshi.
