The United States Soccer Federation, commonly known as U.S. Soccer or USSF, is the national governing body for soccer in the United States. Founded in 1913, the federation oversees and supports the development, organisation, and administration of soccer at national and international levels. It is affiliated with FIFA, the sport’s international governing body, and CONCACAF, the regional governing body for North and Central America and the Caribbean.

U.S. Soccer is responsible for the United States national teams, including the senior men's and women's national teams, youth national teams, and teams participating in other recognised forms of the sport. Its responsibilities extend to international competition, player development, coaching education, referee development, safeguarding, and the establishment of standards and regulations across the American soccer system.

The federation works with professional leagues, state associations, youth organisations, clubs, coaches, referees, players, and other stakeholders. Although professional leagues such as Major League Soccer and the National Women's Soccer League operate independently, U.S. Soccer has a broader governing and development role within the national soccer landscape. Its programmes support participation at recreational, amateur, youth, collegiate, and elite levels.

Education and development are important parts of the federation's activities. Through coaching and referee education programmes, licensing pathways, learning resources, and technical initiatives, U.S. Soccer helps improve the quality and consistency of the game. It also promotes player safety, inclusion, responsible conduct, and standards intended to support a positive sporting environment.

The federation coordinates national-team programmes and international fixtures, supports talent identification and youth development, and collaborates with regional and local soccer organisations to expand access to the sport. Its work also includes communications, commercial partnerships, sponsorships, fan engagement, and long-term strategic planning for the development of soccer across the country.

As a nonprofit governing organisation, U.S. Soccer serves a broad network of participants and institutions rather than operating as an individual football club. Its central mission is to advance soccer in all its forms throughout the United States and to support sustainable growth from grassroots participation to international competition.
