The equestrian events at the 1928 Summer Olympics included dressage, eventing, and show jumping. All three disciplines had both individual and team competitions. The competitions were held from 8 to 12 August 1928. Teams were now fielded by three riders, rather than four, the purpose being to reduce pressure on national federations to find that many riders in order to compete for team medals. Riders had to be considered amateurs, which was defined as either an actively serving professional officer, or as a gentleman rider as defined by the rules of that rider's national governing body. A total of 113 entries were present from 20 nations: Argentina, Austria, Belgium, Bulgaria, Czechoslovakia, Denmark, Finland, France, Germany, Hungary, Italy, Japan, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, and the USA. This was the first appearance for Hungary, Japan and Argentina in equestrian events at an Olympics. Additionally, after being shut out from two Olympic competitions, Germany also returned to the Games to win a few medals in the equestrian events.

The 1928 Summer Olympics, officially known as the Games of the IX Olympiad and commonly known as Amsterdam 1928, was an international multi-sport event that was celebrated from 28 July to 12 August 1928 in Amsterdam, Netherlands. The city of Amsterdam had previously bid for the 1920 and 1924 Olympic Games, but was obliged to give way to war-torn Antwerp in Belgium for the 1920 Games and Pierre de Coubertin's Paris for the 1924 Games.
