Star Soldier is a 1986 vertically scrolling shooter video game developed and published by Hudson Soft for the Nintendo Entertainment System and MSX. It is the first game in the Star Soldier series. The player pilots the starship "Caesar", traveling through space stations occupied by powerful supercomputers known as "Starbrains" who threaten the galactic empire. Star Soldier greatly resembles the earlier arcade game Star Force.

The MSX version of the game was brought to the SG-1000 in Taiwan.
