The Women's State of Origin is an annual rugby league fixture between two Australian state representative women's sides, the New South Wales Blues and the Queensland Maroons. First played in 1999 as the Women's Interstate Challenge, the game was rebranded as State of Origin for the 2018 season. Queensland won the first game in 1999 and were unbeaten for 17 years until New South Wales won for the first time in 2016.
