Warrior is a 1979 arcade fighting game. It is considered one of the first fighting games, excepting several boxing games such as Heavyweight Champ, released in 1976, and Atari's unreleased Boxer (which was cloned as 1980's Boxing for the Atari 2600).

Developed by Tim Skelly while working at Cinematronics, it was released under the Vectorbeam company name shortly before Cinematronics closed Vectorbeam, which they had purchased in 1978. The game featured two dueling knights rendered in monochrome vector graphics and based on crude motion capture techniques. Due to the limitations of the hardware, the processor could not render the characters and gaming environment at the same time, so backgrounds were printed and the characters projected on top of them.
