The men's triathlon was one of the triathlon events at the 2012 Summer Olympics in London, United Kingdom. It took place on 7 August 2012, featuring 55 men from 32 countries. It was the fourth appearance of an Olympic men's triathlon event since the first at the 2000 Olympics in Sydney. The race was around Hyde Park, a 1.42 km² park in central London. The race was held over the "international distance" (also called "Olympic distance") and consisted of 1.5 kilometres (0.93 mi) swimming, 43 kilometres (27 mi) road cycling, and 10 kilometres (6.2 mi) road running.

A sub-twenty degree celsius Serpentine River met the athletes in the swimming discipline. A group of six finished the 1,500 metres (1,600 yd) swim leg in a lead group.Great Britain's Jonathan Brownlee was given a 15-second penalty for an illegal transition between the swimming and cycling disciplines. A large lead group of articles were together at the end of the cycling leg but Jonathan Brownlee's brother Alistair Brownlee (Great Britain) broke away on the run to win the gold medal with Spain's Javier Gómez in second and Jonathan Brownlee in third. Alistair Brownlee earned Great Britain's nineteenth gold medal at the 2012 Games.

Bronze-medallist Jonathan Brownlee collapsed almost immediately after crossing the finish line.Paramedics gave him treatment and diagnosed him with heat stroke. He was taken to the medical tent where it was determined he would suffer no long lasting effects from the incident.

Qualification for the race was restricted to three athletes per National Olympic Committee (NOC), an organisation representing a country at the Olympics, until eight NOCs had three qualified athletes. Once eight NOCs had qualified three athletes; a NOC was limited to two entries. A NOC with an athlete who won one of the five continental championships (Africa, Asia, Pan America, Europe and Oceania) were given one place in the event. Additionally, three places were available for the NOC of the medallists at the International Triathlon Union (ITU) World Qualification Event. Another 38 places were available to the NOCs with the highest ranked athletes on the ITU Olympic Qualification List on 31 May 2012. If an athlete had already qualified through another method the NOC did not receive another quota with it instead going to the next NOC on the ITU Olympic Qualification List. Five more entries into the event were given to one NOC per continental region. This was based on the ITU Olympic Qualification List with the highest ranked athlete from a non-qualified NOC in their continental region qualifying a place for their NOC in the event. One was given to the Great Britain NOC as the hosts but as they had already gained a place, the host place was given to the highest eligible athlete on the ITU Olympic Qualification List's NOC. The final two places for the event was given to two NOCs chosen by the Tripartite Commission.
