The 2009 State of Origin series was the 28th time that the annual three-game series between the Queensland and New South Wales representative rugby league football teams was played entirely under 'state of origin' selection rules. Queensland won their first two matches to retain the shield and to record 14 series wins, as well as the first time in Origin history that a state had won the series for four consecutive years. Maroon centre Greg Inglis was awarded the Wally Lewis Medal as player of the series.
