The association football tournament at the 2012 Summer Olympics was held from 25 July to 11 August, and was the only sport to begin before the official opening day of the Olympic Games, two days before the opening ceremony. It was also the only sport to be held at multiple venues outside London, with Manchester, Glasgow, Newcastle, Coventry and Cardiff all hosting matches. The finals were played at Wembley Stadium. Associations affiliated with FIFA were invited to send their senior women's and men's under-23 national teams to participate; men's teams were allowed to augment their squads with three players over the age of 23. Five hundred and four football players competed for two sets of gold medals.
