The equestrian events at the 2012 Olympic Games in London were held between 28 July and 9 August at Greenwich Park.

Medals were awarded in the following competitions: Each event has its own qualification rules, but generally rely on FEI rankings.

Similar to dressage, teams of four riders were qualified at either the World Equestrian Games (WEG) or through a regional competition.

The WEG awarded five berths, the regions six (America: two, Europe: two, Asia: two), and the hosts (Great Britain).

Similar to dressage, teams of five riders were qualified at either the WEG, a regional competition, or through a composite spot.

The WEG awarded five berths, the regions seven (America: three, Europe: three, Middle East & Africa: one), the hosts (Great Britain).

Additionally, countries who can not make a full team may send riders to compete for individual medals.

The top seven teams (included those tied for 7th) advance to the Grand Prix Special, which is a slightly more rigorous test.

Riders can tailor a test to their horses' strengths, as well as incorporate movements that are more difficult than those required in the Grand Prix or the Special (such as a pirouette in piaffe) in order to increase their scores.
