USASA National Women's Open

It began as a tournament only contested by amateur and semi-pro teams, as teams from professional leagues (WUSA, WPS, and the NWSL) are not allowed to enter the competition. In 2012 though, the Chicago Red Stars, a professional club in the WPSL Elite, entered and won the competition. Similarly, the professional Houston Aces of WPSL won in 2013. The defending Women's Cup champion is Olympic Club, who won the title in back-to-back tournaments in 2015 and 2016. The last open was held in 2016 ==Tournament structure==

2009–2012 In the regional phase of the competition, four to sixteen teams per region compete in a round-robin (or partial round-robin) tournament, playing at least three games. The national finals feature the four regional winners in a two-round knockout tournament. 2013–2016 Teams apply to take part in the national championships, which is contested as an initial round-robin group, followed by a championship game if there are more than four teams participating. ==Finalists==
