A quota of 150 equestrian riders (48 dressage, 48 eventing and 54 show jumping) will be allowed to qualify. A maximum of 12 athletes can compete for a nation across all events (with a maximum of four per discipline). Athletes qualified through various qualifying events and rankings.[1]
If a country does not qualify a team in eventing, it may enter a maximum of two individuals per discipline. A team can be made up of three of four athletes, meaning if reallocation does occur, countries with individuals can qualify teams, respecting the maximum number of teams allowed to compete in each discipline.[1]
Only four nations took part in the South American Qualifier. As three countries qualified teams to the Pan Am Games, only Uruguay qualified the limit of two individual athletes. The last spot was vacant and will be distributed by the FEI World Eventing Ranking.
