David Hourn (born 9 September 1949) is an Australian cricketer. He played 44 first-class matches for New South Wales between 1970/71 and 1981/82. Ian Chappell wrote in a 1977 article about Hourn and fellow spinner Jim Higgs: "in my opinion neither of them are real cricketers. By that I mean they are only bowlers, not cricketers. They are both well below standard as fieldsmen and batsmen." Poor eyesight and knee injuries later in his career did not help Hourn's batting and fielding.
