United States Aquatic Sports (USAS) is the national federation for aquatic sports which represents the United States in FINA. Since by U.S. law and FINA regulations, the United States must have only one national federation for itself to FINA, United States Aquatic Sports has served as the unifying body for the sports since 1980. Five separate national governing bodies (NGBs) make up USAS: USA Swimming, USA Diving, United States Synchronized Swimming, USA Water Polo, and U.S. Masters Swimming. Of the five, only U.S. Masters Swimming (USMS) is not a member of the United States Olympic Committee.
