The 1983 State of Origin series was the second time the annual three-game series between the New South Wales and Queensland rugby league teams was played entirely under "state of origin" selection rules.
After the Australian team had swept all before them in 1982, including sweeping New Zealand in the mid-season tests, before embarking on the highly successful 1982 Kangaroo tour where they became the first touring side to go through undefeated, winning all three Ashes tests against Great Britain and the two tests against France, the 1983 State of Origin series was billed as something of an unofficial World Championship. The winning state would have bragging rights over who had the best representative team in the world outside of the test team.
