The Dungeonmaster (originally Ragewar: The Challenges of Excalibrate and Digital Knights) is a 1984 American anthology fantasy film produced by Charles Band, and is split up into seven distinct story segments, each written and directed by a different person: Dave Allen, Band, John Carl Buechler, Steve Ford, Peter Manoogian, Ted Nicolaou and Rosemarie Turko. The film's theme was influenced by the popularity of Disney's 1982 film Tron and the roleplaying game Dungeons & Dragons.

Principal photography began in 1983 but the film was not completed until 1984. The film features an appearance by the heavy metal band W.A.S.P. The film is known for the line of dialogue "I reject your reality and I substitute my own". A sequel to the movie was shot and edited in 1988, but never completed.
