Reginald Arthur Whitcombe (10 April 1898 – 11 January 1957) was an English professional golfer. Whitcombe began his career at Came Down Golf Club in Dorset and served in the British armed forces during World War I. He was the professional at Parkstone Golf Club from 1 January 1928 until his death in 1957. He finished runner up to Henry Cotton in the 1937 Open Championship at Carnoustie, and in 1938 he won the windswept Open at Royal St George's, where his two final rounds of 75–78 were still enough to beat the halfway leaders by ten strokes. His two older brothers Ernest and Charles were also professional golfers and all three played together for Great Britain in the 1935 Ryder Cup.
