The most series wins in Australia's rugby league State of Origin series is 23, achieved by Queensland between 1982 and 2022.
The annual three-match State of Origin series has been played between New South Wales and Queensland since 1982. Players are selected to represent the Australian state in which they played their first senior rugby league. As of 2022, New South Wales had won 16 times, with two drawn series in 1999 and 2002: on both occasions, the holder was Queensland and they retained the trophy. In 1980 and 1981, a single match was played – these years do not count towards total series wins.
