Sinistar is a multi-directional shooter arcade game developed and manufactured by Williams Electronics. The game was released in 1983, though the in-game copyright notice reads 1982.

The player pilots a lone fighter ship through a quadrant of the galaxy, initially blasting away at drifting planetoids to "mine" Sinisite Crystals from them, which, when harvested, create Sinibombs. Sinibombs are the only weapon capable of damaging Sinistar. The fighter's bomb bay can hold 20 Sinibombs.

Sinistar was also available for many computers and home game systems.
