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.

Originally, the series was to have been played in the traditional mid-season slot; however, due to the COVID-19 pandemic which caused the season to be suspended after round two, the series was moved to November, with the three matches to be played on consecutive Wednesday nights. On 15 May, the NRL announced that the matches would be played on three consecutive Wednesdays after the season's end, these being 4, 11 and 18 November.

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.

2 - Boyd Cordner suffered a concussion in Game 1, eventually leading to him announcing his retirement in 2021. It paved the way for James Tedesco to take over the captaincy from Game 2.

Queensland Maroons
