The men's singles tennis tournament at the 2012 Olympic Games in London was held at the All England Club in Wimbledon from 28 July to 5 August, making it the first Olympic grass court tournament since tennis was re-introduced to the Games. The event was run and organised by the International Olympic Committee (IOC) and the International Tennis Federation (ITF), and is part of the Association of Tennis Professionals tour. Matches were the best of three sets, except for the final which was the best of five sets. Tie-breaks were in use for all sets except the fifth set of the final and the third set of all other matches.

Rafael Nadal was the reigning Gold Medallist, having won the tournament at the 2008 Olympics in Beijing, but withdrew on 19 July 2012 due to a recurring knee injury. Prior to his withdrawal, Nadal was seen as the favourite to retain the Gold Medal, despite losing to Lukáš Rosol in the second round of the Wimbledon Championships a month earlier.

The second-round match between Jo-Wilfried Tsonga and Milos Raonic on 31 July 2012 culminated in a record-setting 3 hours and 57 minutes and 66 total games with a third set ending at 25–23. This was the longest tennis match in Olympic history, in terms of games played, under the best of three sets system. In terms of time, it was, at that time, the longest best of three sets men's singles match in Olympic history.
