Ernest "Ernie" Elliott (1943/1944 – 6 December 1972), nicknamed "Duke", was a Northern Irish loyalist activist and a leading member of the Ulster Defence Association (UDA) during its early days. Unusually for the generally right-wing UDA, Elliott expressed admiration for socialism and communism, and frequently quoted the words of Che Guevara and Karl Marx. Elliott was eventually killed by a fellow UDA member following a drunken brawl, although his death was variously blamed on republicans and a rival faction within the UDA.
