The equestrian events at the 1920 Summer Olympics in Antwerp included eventing, show jumping, vaulting and dressage. The competitions were held from 6 to 12 September 1920. Although 89 riders were competing, many rode in more than one event, with 87 entries total (45 jumping, 17 dressage, 25 eventing). Vaulting was also held, its one appearance at an Olympic Games, with only Belgium, France and Sweden fielding teams.
The requirements for the dressage test remained the same as for the 1912 Games. Team dressage medals were not distributed.
The show jumping competition held both its individual and team competitions on the same day, and riders in the team event could not compete for an individual medal. Therefore, 10 riders total (5 teams and 5 individual) could be sent for the jumping competition, although only Italy and Sweden were able to field that many riders.
The eventing competition removed the dressage test for the 1920 Games, and replaced it with a second roads and tracks phase that was in length. The cross-country test proved to be challenging, with 12 of the 25 horses contesting the course finishing with time faults, and 13 finishing with faults at obstacles.
A total of 89 riders from 8 nations competed at the Antwerp Games:
