Derek Roy (25 August 1922 – 15 March 1981) was an English comedian, whose public profile was at its greatest in the late 1940s and early 1950s. His BBC Radio show, Hip Hip Hoo Roy, was written by amongst others Spike Milligan, and was the show where Milligan's Goon Show character Eccles first appeared. Roy's unsuccessful star-vehicle Happy Go Lucky also gave the first writing break to Ray Galton and Alan Simpson, who would soon team up with the show's last producer Dennis Main Wilson to create Hancock's Half Hour. He died of cancer in March 1981 aged 58.
