The Zap Gun is a 1967 science fiction novel by American writer Philip K. Dick. It was first published as the two-part serial Project Plowshare in Worlds of Tomorrow in 1965 and 1966, before Pyramid Books issued it in paperback under its present title. The novel originated in a title-first commission devised by Pyramid editor Don Bensen and was written in 1964 during a period of rapid production in Dick's career.
