USASA National Women's Open
The USASA National Women's Open is an American women's soccer tournament run by the United States Adult Soccer Association. It began in 1996, and from 2009-2012 it was known as the Women's Cup. Before the formation of the Women's Open, the Women's Amateur was the top national cup competition.
Historically, it has only been contested by amateur and semi-pro teams, as teams from WUSA and WPS have never entered the competition. In 2012 though, the Chicago Red Stars, a professional club in the WPSL Elite, entered and won the competition.
The national finals feature the four regional winners in a two-round knockout tournament.
Teams apply to take part in the national championships, which is contested as a round-robin group.
