List of Olympic medalists in equestrian

Equestrian sports are among those contested at the Summer Olympic Games. Equine events began at the Olympics in 1900, when competitions in polo (considered by the International Olympic Committee (IOC) to be a separate sport from the other equestrian events), vaulting, four-in-hand driving, mail coach driving, mixed hacks and hunters and three types of jumping (high jump, long jump and show-jumping) were held. Most of these events were later discontinued, although equestrian events have continued through the 2008 Summer Olympics, and now include team and individual dressage, three-day eventing and show-jumping. Competitors in the modern pentathlon event also have to complete an equestrian show-jumping course, but this is not part of the equestrian events.

Modern-day Olympic equestrian events are rooted in cavalry skills and classical horsemanship, and through 1948, competition was restricted to active-duty officers on military horses. Only after 1952, as mechanization of warfare reduced the number of military riders, were civilian riders allowed to compete. Equestrian is the only Olympic sport in which animals compete with humans, and is one of four sports in which the genders compete against each other, the others being some sailing divisions, mixed doubles division in tennis and the mixed doubles division of badminton. The rules for Olympic equestrian competition are set by the Fédération Équestre Internationale, the international governing body for equestrian sports.
