Superworld is a superhero-themed role-playing game published by Chaosium in 1983 that uses the generic Basic Role-Playing rules system. The game began as just one part of the Worlds of Wonder product before being published as a stand-alone game. In competition against other well-established and popular superhero games, Superworld never found an audience, and was discontinued after only three supplements were published for it.

Stephen Herbert Perrin was an American game designer and technical writer/editor, best known for creating the tabletop role-playing game RuneQuest for Chaosium.
