The State of Origin is a best-of-three rugby league series between two Australian state representative sides: New South Wales Blues and the Queensland Maroons.
Two games are played in the home states of the two teams, with a third game played at a neutral venue. The team that wins two games out of three is declared the State of Origin series winner.
The first State of Origin took place in 1980 and the series has evolved into one of the fiercest rivalries in Australian sport.
