The men's high jump was an event at the 1956 Summer Olympics in Melbourne, Australia. Twenty-eight contestants from 19 nations met on the morning of the first day of the athletic contests, on Friday November 23, 1956, and 22 cleared the qualifying height of 1.92 metres, to meet again in the afternoon. The maximum number of athletes per nation had been set at 3 since the 1930 Olympic Congress. The event was won by Charles Dumas of the United States, the nation's second consecutive and 11th overall victory in the men's high jump. Chilla Porter's silver was Australia's second medal in the event (after a gold in 1948). Igor Kashkarov's bronze was the Soviet Union's first.
