Don Priestley (born 1940) is a teacher and former video game programmer who wrote over 20 commercial games for the ZX81 and ZX Spectrum home computers between 1982 and 1989. Despite successful releases for DK'Tronics, such as 3D Tanx and Maziacs, Priestley returned to teaching in the late 1980s, claiming changes in the video game industry did not suit his style of work.
