USA Track & Field (USATF) is a United States national governing body for the sports of track and field, cross country running, road running, and racewalking. The USATF was known between 1979 and 1992 as The Athletics Congress (TAC) after its spin-off from the Amateur Athletic Union (AAU), which governed the sport in the US through most of the 20th century until the Amateur Sports Act of 1978 dissolved its responsibility. Based in Indianapolis, USATF is a non-profit organization with a membership of more than 130,000. The organization has three key leadership positions: CEO Max Siegel, Board of Directors Chair Steve Miller, and elected president Vin Lananna. U.S. citizens and permanent residents can be USATF members, but permanent residents can only participate in masters events in the country, and they cannot win USATF medals, prize money, or score points for a team, per World Athletics regulations.

Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. In British English the term "Athletics" is synonymous with American "Track and Field" and includes all jumping events.
