A race track (racetrack, racing track or racing circuit) is a facility built for racing of vehicles, athletes, or animals (e.g. horse racing or greyhound racing). A race track also may feature grandstands or concourses. Race tracks are also used in the study of animal locomotion.

A racetrack is a permanent facility or building. Racecourse is an alternate term for a horse racing track, found in countries such as the United Kingdom, India, Australia, Hong Kong, and the United Arab Emirates. Race tracks built for bicycles are known as velodromes. Circuit is a common alternate term for race track, given the circuit configuration of most race tracks, allowing races to occur over several laps. Some race tracks may also be known as speedways, or raceways.

A race course, as opposed to a racecourse, is a nonpermanent track for sports, particularly road running, water sports, road racing, or rallying. Many sports usually held on race tracks also can occur on temporary tracks, such as the Monaco Grand Prix in Formula One.
