David Palmer (born 28 June 1976 in Lithgow, New South Wales) is a professional squash player from Australia. He won the Super Series finals in 2002, the World Open in 2002 and 2006; the British Open in 2001, 2003, 2004 and 2008; and the Australian Open in 2008. He attained World No. 1 ranking in September 2001 and again (for one month) in February 2006.
In technical terms, Palmer plays a classic all-court attrition game with hard-hitting attacking shots from his opponent's loose shots. He is known for the power of his striking, and the strength of his physical play, contributed to by rigorous attention to fitness. His training regime involves completing the multi-stage fitness test five times with a three-minute break between tests.
