The United States Soccer Federation (USSF), commonly referred to as U.S. Soccer, is a 501(c)(3) nonprofit organization and the official governing body of the sport of soccer in the United States. Headquartered in Chicago, the federation is a full member of FIFA and governs American soccer at the international, professional, and amateur levels, including: the men's and women's national teams, Major League Soccer, National Women's Soccer League, youth organizations, beach soccer, futsal, Paralympic, and deaf national teams. U.S. Soccer sanctions referees and soccer tournaments for most soccer leagues in the United States. The U.S. Soccer Federation also administers and operates the U.S. Open Cup and the SheBelieves Cup.

The United States Soccer Federation (USSF) governs most levels of soccer in the United States, including the national teams, professional leagues, and amateur leagues, being the highest soccer authority in the country. The National Collegiate Athletic Association (NCAA) governs most colleges; secondary schools are governed by state-level associations, with the National Federation of State High School Associations (NFHS) setting the rules at that level. The match regulations are generally the same between the three governing bodies although there are many subtle differences.
