Great Britain's Andy Murray defeated Switzerland's Roger Federer in the final, 6–2, 6–1, 6–4 to win the gold medal in men's singles tennis at the 2012 Summer Olympics.

Federer was attempting to become the third man to complete the career Golden Slam in singles (after Andre Agassi and Rafael Nadal).

In the bronze medal match, Argentina's Juan Martín del Potro defeated Serbia's Novak Djokovic, 7–5, 6–4.

[7] Rafael Nadal was the reigning gold medalist from 2008,[6] but withdrew due to a recurring knee injury.

[8] Despite his early exit at Wimbledon the previous month, Nadal was the pre-Olympics favourite to retain his Gold Medal.

[9] The second-round match between Jo-Wilfried Tsonga and Milos Raonic lasted 3 hours and 57 minutes and 66 games, with the third set ending at 25–23.

This was (then) the longest tennis match in Olympic history, in terms of games played and in time, under the best-of-three-sets system.

[10][11][12] However, this record was quickly eclipsed by Federer and del Potro three days later in a semifinal encounter that lasted 4 hours 26 minutes, with the third set ending at 19–17.
