The 1980 State of Origin game was the first game between the Queensland Maroons and the New South Wales Blues rugby league teams to be played under "state of origin" selection rules. It was the third match of 1980's annual interstate series between the Blues and the Maroons, and was only allowed to go ahead because the first two matches (and the title) were already won by New South Wales. It was played on 8 July 1980 under the newly configured rules by which a player would represent his "state of origin", i.e. the state in which he was born or in which he started playing registered first grade rugby league football.
