Peter Douglas Conyers Walker (7 October 1912 – 1 March 1984) was an English racing driver. He was born in Huby, Yorkshire and died in Newtown, Worcestershire. He proved a strong driver in most disciplines, but was most adept in sports cars, winning the 1951 24 Hours of Le Mans race, and the Goodwood Nine-Hours in 1955. He effectively retired after a crash in 1956 left him with serious injuries.
