USA Rugby (officially the United States of America Rugby Football Union, Ltd.) is the national governing body for the sport of rugby union in the United States. USA Rugby states its role as "the national governing body charged with achieving and maintaining high levels of quality in all aspects of rugby." USA Rugby is responsible for the promotion and development of the sport in the U.S. and promotion of U.S. international participation. USA Rugby is a member of World Rugby (WR) and a member of the United States Olympic Committee (USOC).
USA Rugby has over 115,000 members, the largest segment being college rugby with over 32,000 members. USA Rugby oversees 1,200 high school teams, 900 college teams, 700 senior club teams, and 400 youth teams. USA Rugby administers all United States national teams: senior men's and women's teams, sevens teams for both men and women, and under-20 national teams for both sexes. The organization also sponsors college rugby for both sexes, although since the 2010–11 academic year the NCAA has designated women's rugby an emerging varsity sport.
