Studio Gokumi (株式会社Studio五組) is a Japanese animation studio established by former Gonzo members.

Studio Gokumi, literally meaning “Studio Group 5”, was founded in May 2010 after members of Gonzo’s Studio Number 5 left the company to start one of their own. Studio Number 5 was responsible at Gonzo for the anime series Strike Witches and Saki.

Studio Gokumi’s first production was an original video animation for Koe de Oshigoto! at the end of 2010. In spring 2011, A Channel debuted as the first anime television series for the studio. Production of Saki was taken over by Studio Gokumi for the Saki: Achiga-hen season, which aired from April 9 to July 2, 2012.
