The United States Specialty Sports Association (USSSA) is a volunteer, sports governing body and a 501(c)(3) nonprofit organization based in Viera, Florida. Originally USSSA stood for United States Slowpitch Softball Association. 

However, in 1998, USSSA rebranded the name to United States Specialty Sports Association, because it expanded into other sports, including youth girls fastpitch, boys baseball, youth basketball, martial arts and more. USSSA governs 13 sports across the US, Puerto Rico, various US Military bases and Canada, and has a membership of over 3.7 million.
