Saru Brunei (サルブルネイ) was a Tokyo-based video game development company founded by graphic designer Gento Matsumoto in 1990. Early works include Pop-Up Computer and Jungle Park.

The label worked in partnership with Nintendo between 1996 and 2003 as a part of Marigul Management.

Saru Brunei was responsible for the cancelled Nintendo 64 game, Doubutsu Banchou (lit. Animal Leader), which was coded by Intelligent Systems. The studio then ported the game to the GameCube as Cubivore: Survival of the Fittest in 2002. The game was published by Nintendo in Japan, but published by Atlus in North America. Other games include Jungle Park on PlayStation and Jungle Park: Saturn Jima on Sega Saturn.

Saru Brunei was made defunct as Marigul was liquidated in May 2003. The label is still used by Gento Matsumoto himself.
