The 2011 State of Origin series was the 30th annual best-of-three series of interstate rugby league football matches between the Queensland and New South Wales representative teams contested under "State of Origin" selection rules. For the third successive year a Queensland victory set a new record for consecutive State of Origin titles, reaching six. Game I was played in Brisbane, Game II in Sydney and Game III was again played in Brisbane. Game III was also Australia's most watched sports TV programme for the year 2011.
Mal Meninga continued on as coach of Queensland whilst New South Wales had chosen to follow the successful Maroons approach by appointing Ricky Stuart as a full-time Origin coach (with no other club commitments) in an attempt to rebuild a winning mentality for the team and the State, after being beaten in the 2010 series 3–0 for the first time since 1995. Despite a much improved New South Wales outfit, Queensland stretched their series-winning streak to six titles, securing it with a 34–24 victory in the third and deciding game of the series in front of a record equalling 52,498 fans at Suncorp Stadium. The series also marked Queensland skipper Darren Lockyer's final series, winning in his 36th and final State of Origin game. Queensland hooker Cameron Smith was awarded the Wally Lewis Medal as Player of the Series.
