The individual eventing was an equestrian event held as part of the Equestrian at the 1964 Summer Olympics programme. The event was held 16 October through 19 October.
Results
There was a dressage test, an endurance test, and a jumping test. The penalties accrued in each were summed to give a final score. It was possible to earn negative penalties in the endurance test; thus, some pairs finished with a negative score.
