Stephen David Williams OBE (born 15 April 1976 in Leamington Spa[1]) is an English rower and double Olympic champion.

Williams was educated at Monkton Combe School, Bath, where he began rowing aged 13.

Williams was the only member of the 2004 Olympic crew to continue racing in the 2005 season, joining Alex Partridge, Pete Reed and Andrew Triggs Hodge in the coxless four, again winning the World Championship that year and in 2006, before coming in fourth at the 2007 world championships.

In 2008, Partridge was replaced in the four by Cambridge Blue Tom James, and - despite an injury-torn season - the quartet became Olympic Champions, defeating the Australian boat by 1.28s on the day dubbed 'Super Saturday' by the media owing to the large GB medal haul.

The Australians led for much of the race before a push by the British boat overhauled them in the last 400 m. Williams was appointed as a fitness consultant to Andy Liddell for Ipswich Town Football Club on 3 July 2012.
