William Murdoch Hamilton (16 February 1938 – 22 October 1976) was a Scottish footballer, who played for Sheffield United, Middlesbrough, Heart of Midlothian, Hibernian and Aston Villa, and gained one cap for Scotland. He became known for his off field lifestyle which overshadowed his playing ability. His one-time manager Jock Stein later described him as comparable to Kenny Dalglish in footballing talent.
