At the 1904 Summer Olympics, seven boxing events were contested, with the sport making its Olympic debut. The competitions were held on Wednesday, September 21, 1904 and on Thursday, September 22, 1904. Contestants in lighter weight classes could also compete in heavier classes. Oliver Kirk, winning the bantamweight and featherweight categories, thus became the only boxer to have won two gold medals in the same Olympics. George Finnegan, Harry Spanjer and Charles Mayer won one gold and one silver medal.
