Defender of the Crown is a strategy computer game designed by Kellyn Beck. It was Cinemaware's first game, and was originally released for the Commodore Amiga in 1986, setting a new standard for graphic quality in home computer games.

In 1987 it was ported to the Commodore 64, Atari ST, MS-DOS, and Macintosh. It was later ported to the Nintendo Entertainment System (NES), Amstrad CPC, Apple IIGS, CDTV, CD-i, Atari Jaguar and Intellivision. An unofficial ZX Spectrum port was also produced. A sequel, Defender of the Crown II, was released in 1993 for the CDTV and Amiga CD32. Two remakes have been released: Robin Hood: Defender of the Crown in 2003 and Defender of the Crown: Heroes Live Forever in 2007.
