The men's 100 metres sprint event at the 1972 Olympic Games in Munich, West Germany, was held at Olympiastadion on 31 August and 1 September. Eighty-five athletes from 55 nations competed. Each nation was limited to 3 athletes per rules in force since the 1930 Olympic Congress. The event was won by Valeriy Borzov of the Soviet Union, the first medal in the men's 100 metres for that nation. Jamaican Lennox Miller, silver medalist four years earlier, became the second man to make the podium twice in the event by taking bronze (after Ralph Metcalfe in 1932 and 1936).
