The equestrian sports were held at Santa Anita Racetrack, which offered stabling for up to 2100 horses, a grandstand with almost 16000 seats, and was managed by experienced horsemen. However, this was the first time the individual jumping competition was not held in the Olympic Stadium immediately prior to the closing ceremonies, as was tradition, and instead held with the other equestrian events at the racetrack. Horses were required to be at least 6 years old. Up to 14 riders and 22 horses were permitted per country. In total 157 entries from thirty nations (Argentina, Australia, Austria, Belgium, Bermuda, Brazil, Canada, Chile, Denmark, Ecuador, Finland, France, Federal Republic of Germany (FRG), Great Britain, Guatemala, Ireland, Italy, Japan, Mexico, Netherland, New Zealand, Norway, Peru, Puerto Rico, Spain, Sweden, Switzerland, USA, Virgin Islands, and Yugoslavia) competed.
