The Women's South Island League is an amateur status league competition run by Southern Football and Mainland Football for Association football clubs located in the South Island of New Zealand. It is at the second level of New Zealand Football behind the national association based New Zealand Women's National League, and the highest level of club based football available to teams within the region.
In March 2023, New Zealand Football announced a change to the Women's National League to move to a fully club-based model, the same as the three regional leagues of the men's competition, when club capability allows. Targeted for 2026, South Island clubs will be competing in the Women's National League. To support this, Mainland and Southern federations will jointly deliver a South Island league, and it will act as a pilot for future incorporation into the league, as the Southern League does for the men's competition.
