The NRL State Championship is a rugby league match played in Australia. It is contested by the premiers of the two elite second-tier competitions in Australia, the New South Wales Cup and the Queensland Cup. The match has been played as a curtain-raiser to the NRL Grand Final at Stadium Australia since it was introduced by the National Rugby League (NRL) in 2014. The match acts as a Super Bowl-type to determine the National Reserve Grade Champions. The winner of the match is crowned the NRL State Champions.

The origins of the NRL State Championship can be traced back to an idea from the Queensland media during the 1984 Brisbane Rugby League season when two club sides had agreed to play a one-off match. The match is played on NRL Grand Final day, and between 2014 and 2017, it was played after the now-defunct NRL Youth Grand Final and before the NRL Grand Final. In 2018, the match was played after the NRL Womens Grand Final and before the NRL Grand Final. Since 2019, it has been played before the NRL Womens Grand Final and the NRL Grand Final.

The 2020 NRL State Championship was not played due to the cancellation of the state premierships after Round 1 caused by the Coronavirus pandemic, and it wasnt played in. The South Sydney Rabbitohs and the Brisbane Tigers played in the 2023 NRL State Championship match, which was held on October 1, 2023, at Accor Stadium.
