Damon Murphy (born 15 December 1984) is an Australian professional rugby union referee and a former national captain for Australia in rugby sevens. His usual position was on the wing.

He was selected for the Australian 7s team in 2004. After three seasons, including representing his country at the 2006 Commonwealth Games in Melbourne, he refocused on fifteen-a-side rugby and signed with the Melbourne Rebels to play in the Australian Rugby Championship.
Resuming his career with the national sevens team, Murphy was Australia's leading points scorer in the 2007–08 World Series. He played in the 2009 Rugby World Cup Sevens. He also captained the side.
