The United States Adult Soccer Association (USASA) is a national organization and sanctioning body for amateur soccer in the United States. It consists of 54 state organizations as well as regional, national and state leagues.
There are numerous adult leagues that are affiliated with the USASA. These leagues are mostly independent of each other, and the division rankings cannot be reliably compared between state or local organizations. There are affiliated leagues and national leagues, in which the national leagues operate leagues constructed out of localized conferences, while multi-state and regional leagues operated leagues that focus on competition with less emphasize on national appeal. USASA has over 250,000 adult members within its leagues and teams.
