The men's 110 metres hurdles event at the 1972 Summer Olympics in Munich was held from 3–7 September. Thirty-nine athletes from 27 nations competed. The maximum number of athletes per nation had been set at 3 since the 1930 Olympic Congress. The event was won by Rod Milburn of the United States, the nation's ninth of nine consecutive victories and the 15th overall gold medal in the event for the Americans. Guy Drut's silver was France's first medal in the event and the best result by a non-American since 1936.
