Athletics at the 1952 Summer Olympics – Men's 100 metres
The men's 100 metres sprint event at the 1952 Olympic Games in Helsinki, Finland was held at the Olympic Stadium on 20 and 21 July. Seventy-two athletes from 33 nations competed; each nation was limited to 3 runners. The final was won by American Lindy Remigino, the fourth consecutive victory by a different American. Herb McKenley won Jamaica's first medal in the men's 100 metres with his silver, while McDonald Bailey's bronze put Great Britain on the podium for the first time since 1928. The final was "probably the closest mass finish in Olympic 100 metre history" with the first four runners all clocking in at 10.4 seconds hand-timed, all six finalists within 0.12 seconds electric-timed (10.79 for first, 10.91 for sixth), and a photo finish necessary to separate the winners.
