Terrence E. Westbrook (born May 1938) is a South African professional golfer. Westbrook lost his left hand's middle finger and a large portion of his left thumb in a childhood accident. Despite this he managed to become a professional golfer. One of his earliest successes was at the 1963 Dunlop South African Masters where he finished joint runner-up, three behind Bruce Keyter. His first professional victories were at the Cock of the North tournament in Zambia. Westbrook won the event in 1966 and successfully defended the championship twice.
