The individual show jumping in equestrian at the 1948 Summer Olympics in London was held at the Wembley Stadium on 14 August. The competition consisted of a single round of jumping. In the case of a tie in points, a jump-off was arranged. The jump-off had no time limit, however, the time taken to complete the jump-off was used as a tie-breaker. The points from the individual competition were also used in the team competition. There were 44 competitors from 15 nations, with nations able to send up to three riders each. The event was won by Humberto Mariles of Mexico, with his teammate Rubén Uriza taking silver at the top of a three-way jump-off for second place. Mariles' win was Mexico's first victory in the event. Jean-François d'Orgeix of France earned that nation's first individual jumping medal since 1928 with his bronze.

The equestrian events at the 1948 London Summer Olympics included dressage, eventing, and show jumping. All three disciplines had both individual and team competitions. The competitions were held from 9 to 14 August 1948, with the first five days held in the military complex at Aldershot, the endurance day on the army grounds of Aldershot at Tweseldown, and the jumping at the Empire Stadium in Wembley. World War II resulted in a greatly reduced number of competitors, including the absence of Germany, although Brazil made its first appearance in the equestrian events. 103 entries from 17 nations competed. The youngest participant was Aëcio Coelho from Brazil at 23 years old, while the oldest rider was the Italian Alessandro, Count Bettoni Cazzago, at 55 years old.
