The NSW League One Women is an Australian semi-professional association football league comprising teams from New South Wales. The league sits at Level 2 on the New South Wales league system, behind the National Premier Leagues NSW Women's, (Level 3 of the overall Australian league system). The competition is administered by Football NSW, the governing body of the sport in the southern region of the state (the northern region governed by Northern NSW Football). From the 2022 seasons onwards, the league name changed from "National Premier League 2 NSW Women's" to "Football NSW League One Women's".^[1]

Following a review by the FFA of state league competitions in Australia, it was announced that they would nationalise the competitions under the one national banner, the National Premier Leagues from the 2013 seasons onwards.^[2] This saw the first and second-tier leagues of the state renamed under the banner.

The inaugural NSW NPL2 Women's premiers in 2013 were Western NSW Mariners, while the inaugural champions were UNSW FC.
