Robot Jox is a 1990 American post-apocalyptic mecha science-fiction film directed by Stuart Gordon and starring Gary Graham, Anne-Marie Johnson and Paul Koslo. Co-written by science-fiction author Joe Haldeman, the film's plot follows Achilles, one of the "robot jox" who pilot giant machines that fight international battles to settle territorial disputes in a dystopian, post-apocalyptic world.

After producer Charles Band approved Gordon's initial concept, the director approached Haldeman to write the script. Gordon and Haldeman clashed frequently over the film's tone and intended audience. Principal photography finished in Rome in 1987, but the bankruptcy of Band's Empire Pictures delayed the film's release in theaters until 1990. It earned $1,272,977 in domestic theatrical gross, failing to return its production cost. Robot Jox received negative critical response and little audience attention upon its first theatrical run. The film has been released on various home video formats, most recently on Blu-ray in July 2015.
