The U.S. Anti-Doping Agency (USADA) is the national anti-doping organization for the Olympic movement in the United States. The U.S. Congress recognized USADA as "the official anti-doping agency for Olympic, Pan American and Paralympic sport in the United States."

Since its inception in 2000, USADA has worked to preserve the integrity of competition, inspire true sport and protect the rights of athletes in the Olympic & Paralympic movement in the United States. With the vision to be the guardian of the values and life lessons learned through true sport, our organization's anti-doping programs are comprehensive, including in-competition and out-of-competition testing, results management and adjudication processes, drug reference resources and therapeutic use exemption process, scientific research initiatives, and athlete and outreach education. We continue to work to improve our system and anti-doping endeavors to further protect clean athletes and the health of future athletes.
