The 1968 Olympic football tournament was played as part of the 1968 Summer Olympics. The tournament features 16 men's national teams from five continental confederations. The 16 teams are drawn into four groups of four and each group plays a round-robin tournament. At the end of the group stage, the top two teams advanced to the knockout stage, beginning with the quarter-finals and culminating with the gold medal match at the Azteca Stadium on 26 October 1968. This was the first time an Asian team won a medal, Japan claiming bronze.

Football at the Summer Olympics, also referred to as the Olympic Football Tournament, has been included in every Summer Olympic Games as a men's competition sport, except 1896 and 1932. Women's football was added to the official program at the Atlanta 1996 Games.
