USA Softball is the national governing body for softball in the United States. It regulates competition to promote fairness and equal opportunity for players, and sanctions events in every state through a network of state and metropolitan associations. The organization reports more than 120,000 teams and a membership of over one million players, coaches, and umpires.

USA Softball supports the sport at multiple levels through membership and registration, adult and Junior Olympic programs, tournaments, and national championships. Its six national team programs represent the United States in international competition, while its High Performance Program provides a pathway for athletes seeking national-team opportunities. The organization also offers umpire training, certification, schools, clinics, rules guidance, and official resources for coaches and tournament directors.

Additional services and resources include the All-American Games, the Junior Olympic Cup, athlete support information, safe softball guidance, and a resource center for amateur softball.
