Star Trek: Strategic Operations Simulator (also known as Star Trek: SOS and Star Trek Arcade) is a space combat simulation arcade game based on the original Star Trek television program and movie series, and released by Sega in 1983. It is a vector game, with both a two-dimensional display and a three-dimensional first-person perspective. The player controls the Starship Enterprise, and must defend sectors from invading Klingon ships.

The game was presented in two styles of cabinets: an upright standup, and a sit-down/semi-enclosed deluxe cabinet with the player's chair modeled after the Star Trek Motion Picture's bridge chairs with controls integrated into the chair's arms.

Star Trek: SOS was ported to the Commodore 64, TI-99/4A, Atari 8-bit family, Atari 5200, Atari 2600, VIC-20, ColecoVision and Apple II.
