The 2020 State of Origin series was the 39th annual best-of-three series between the Queensland and New South Wales rugby league teams. Before this series, Queensland has won 21 times, NSW 15 times, with two series drawn. For just the third time, a game was played away from Sydney, Brisbane or Melbourne, with Game 1 played at Adelaide’s Adelaide Oval. Before the start of the series, Daily Telegraph journalist Dean Ritchie described the Queensland team as the worst ever Maroons side. Queensland would go on to upset a highly fancied New South Wales side and win the series 2–1.
