The men's football tournament at the 2012 Summer Olympics was held in London and five other cities in Great Britain from 26 July to 11 August. Associations affiliated with FIFA were invited to enter their men's U-23 teams in regional qualifying competitions, from which 15 teams, plus the hosts Great Britain, reached the final tournament. Men's teams were allowed to augment their squads with three players over the age of 23. It was the first major FIFA-organised men's tournament to be held within the United Kingdom since the 1966 FIFA World Cup and was the first men's Olympic football tournament to feature a team representing Great Britain since the 1960 Summer Olympics in Rome.
Each National Olympic Committee may enter one men's team in the football tournament.

For the first matchday at St James' Park, there were long queues at the box office, leading to fans missing some of the game. A spokesman for Ticketmaster said: "We saw extremely high numbers of spectators arriving at St James' Park to purchase football tickets on the day of the event. While Ticketmaster is contracted to manage the box offices at Olympic venues, the staff numbers at those venues are determined by LOCOG. We will continue to work closely with LOCOG to ensure that the box office staff levels are sufficient to meet the demands for ticket sales and collection". LOCOG described the situation as "totally and completely 100% unacceptable", and after changes were made in the process, the issue was reportedly avoided for the second round of matches.
During the matches held at the Wembley Stadium on 29 July, fans were subjected to long queues at the concession stands in the ground after Visa's card payment system crashed, leaving cash payment as the only alternative. The situation was compounded by the fact that, as Visa had been granted exclusive rights to the Olympics, other cards could not be accepted as payment, and the number of cash machines in the stadium had been reduced after 27 that worked on the LINK system had been removed to be replaced by eight that could only be used by Visa cards.
There were several problems relating to transport for events held at the Millennium Stadium in Cardiff. There was severe congestion at Cardiff Central railway station when Great Britain played South Korea; and the bronze medal match also had rail disruption when a retaining wall collapsed onto the tracks.
Swiss footballer Michel Morganella was sent home by the Switzerland team following their 2-1 loss against South Korea after he sent a tweet that, according to the director of Swiss Olympic Committee Gian Gilli, "discriminated, insulted and violated the dignity of the South Korean football team and people".
Following the criticism against Scottish female player Kim Little, for choosing not to sing the British national anthem "God Save the Queen" because of her national identity, other Scottish and Welsh players, Ryan Giggs, Craig Bellamy and Ifeoma Dieke, also attracted comment in the media for remaining silent. Giggs, the Great Britain men's captain, later said: "The problem is the British anthem is the same as the English anthem and if you're a Welshman or a Scotsman it's difficult".
After South Korea defeated Japan in the bronze medal match at the Millennium Stadium in Cardiff on 10 August, South Korean player Park Jong-woo walked around the field holding a banner with a political message written in Korean, " ?!" (dokdo neun uri ttang, lit.: "Dokdo is our territory"). This incident occurred on the same night after South Korean President Lee Myung-bak had visited the islands which both South Korea and Japan claim as their territory. The IOC and FIFA reviewed the evidence, since FIFA statutes prohibit political statements being made by athletes at Olympic events. The IOC barred Park from the bronze medal ceremony and did not permit him to receive his medal. In addition, it asked FIFA to discipline Park, and stated that it may decide on further sanctions at a later date. IOC president Jacques Rogge told reporters: "We will take a possible decision of what will happen with the medal later". FIFA failed to reach a conclusion on the case at a meeting at its Zürich headquarters held on 5 October, and the disciplinary committee discussed the case again on the following week, then again failed to reach a verdict. After that, the Korean Olympic Committee (KOC) announced that Park would receive his bronze medal. The case was heard again by the committee on 20 November, and FIFA finally decided and announced on 3 December to suspend Park for two matches after he was considered to have breached the FIFA Disciplinary Code and the Regulations of the Olympic Football Tournaments. FIFA also imposed a warning on the Korea Football Association and reminded it of its obligation to properly instruct its players on all the pertinent rules and applicable regulations before the start of any competition, in order to avoid such incidents in the future. The Korea Football Association was warned that should incidents of such nature occur again in the future, the FIFA Disciplinary Committee may impose harsher sanctions on the Korea Football Association.
