Donald Allen Curtis (22 October 1904 – 18 October 1983) was an English professional golfer.
In 1926 he lost in a playoff for the Findlater Shield, the assistants' championship.
He had tied with Walter Thomas but lost the 18-hole playoff after a disappointing 82.
Curtis's first big success was when he won the 1936 News Chronicle Tournament.
Curtis reached the semi-final of the 1937 News of the World Match Play where he lost to Percy Alliss by 1 hole.
The following year he won the Dunlop-Southport Tournament at Southport and Ainsdale Golf Club, beating Arthur Lees by 2 strokes and taking the £315 first prize.
Later in 1938, he was one of the runners-up in the News Chronicle Tournament behind Reg Whitcombe.
