The men's high jump event at the 1984 Summer Olympics in Los Angeles, California, was held at the Los Angeles Memorial Coliseum on 10–11 August 1984. Thirty athletes from 20 nations competed. The maximum number of athletes per nation had been set at 3 since the 1930 Olympic Congress. The event was won by Dietmar Mögenburg of West Germany, the nation's first victory in the men's high jump. Patrik Sjöberg's silver was Sweden's first medal in the event since 1920. Zhu Jianhua won bronze in the People's Republic of China's first appearance. The United States, which had made the podium in each of the 18 editions of the high jump before the 1980 boycott, now missed the podium for the first time in which the country competed, as Dwight Stones in fourth place fell just short of becoming the first man to earn three medals in the event.

Dietmar Mögenburg is a (West) German former high jumper who won gold medals at the 1984 Summer Olympics in Los Angeles and at the 1982 European Championships in Athens.
