Dream Park is a 1981 sci-fi/murder mystery novel by American writers Larry Niven and Steven Barnes, set in a futuristic amusement park of the same name. It was nominated for the 1982 Locus Award and later expanded into a series of cyberpunk murder mysteries: The Barsoom Project (1989), The California Voodoo Game (1992), and The Moon Maze Game (2011). The books describe a futuristic form of live action role-playing games (LARPs), although the term was not in use when the original novel was published. The novels inspired many LARP groups, notably the International Fantasy Games Society, named after a fictional entity in the book.
