László Papp was a Hungarian professional boxer from Budapest. He was left-handed and won gold medals in the 1948 Summer Olympics in London, the 1952 Summer Olympics in Helsinki, and the 1956 Summer Olympics held in Melbourne, Australia. In his final Olympic competition he became the first boxer in Olympic history to win three successive gold medals. He won 12 of his 13 Olympic fights without losing a round, dropping only one, in his last Olympic final, to American boxer José Torres. There was not another triple gold medalist for 20 years, when Cuba's Teófilo Stevenson won three, followed by another Cuban Félix Savón as the third of the three men to accomplish the feat.

The 1956 Summer Olympics, officially known as the Games of the XVI Olympiad, were an international multi-sport event held in Melbourne, Victoria, Australia, from 22 November to 8 December 1956, with the exception of the equestrian events, which were held in Stockholm, Sweden, in June 1956.
