The men's triple jump event was part of the track and field athletics programme at the 1948 Summer Olympics. The competition was held on 3 August 1948. Twenty-eight athletes from 17 nations competed. The maximum number of athletes per nation had been set at 3 since the 1930 Olympic Congress. The final was won by Arne Åhman of Sweden. It was Sweden's first victory in the event since 1912, and first medal since 1932. Australia reached the podium for the second Games in a row (albeit twelve years apart) with Gordon George Avery's silver. Turkey received a medal in its first appearance in the triple jump with Ruhi Sarialp's bronze; it was the only track and field athletics medal won by Turkey in the 1900s.
