Douglas Marmaduke Caston (born: September 17, 1917 Macklin, Saskatchewan, Canada - died: June 26, 1996 [Edmonton, Alberta] ) was a newspaper publisher and served as a Canadian federal politician from 1967 until 1968.
Caston ran for a seat in the Canadian House of Commons in a by-election on November 6, 1967. He defeated Liberal candidate Allen Sulatycky to win the Jasper—Edson riding. Parliament would be dissolved a year later and Caston ran for re-election in the new Rocky Mountain electoral district as Jasper—Edson was abolished. Caston would run against Sutlatycky for the second time. An unusual event happened in that election as the Progressive Conservatives had 2 endorsed candidates running under their party banner for that district. Sulatycky would win and Caston was defeated finishing third behind the other Progressive Conservative candidate Hugh Gourlay.
