Omega Boost is a 1999 shoot 'em up video game developed by Polyphony Digital and published by Sony Computer Entertainment for the PlayStation. It is the first game to be developed by Polyphony Digital, formed after the success of Gran Turismo which was developed under Sony Computer Entertainment Japan, and their only game that is not in the Gran Turismo series.

The game features mecha designs by Shoji Kawamori of Macross fame. The game was criticized by some reviewers for being too short (nine levels with an equal amount of unlockable special missions) and simplistic.
