The 2013 State of Origin series was the 33rd time the annual best-of-three series between the Queensland and New South Wales rugby league teams was played entirely under 'state of origin' rules. It was the first series to be administered by the Australian Rugby League Commission which was created in a major re-structure of the sport's administration in Australia.
Originally, Queensland were to host two home matches this year, however the ARLC Commission announced in November 2012 a new five-year cycle which would see New South Wales instead host two home matches this year, as well as in 2016, the Maroons to host two home matches in 2014 and 2017 and the remaining match in 2015 to be hosted at a neutral venue
