Belarus' Victoria Azarenka and Max Mirnyi defeated Great Britain's Laura Robson and Andy Murray in the final, 2–6, 6–3, [10–8] to win the gold medal in Mixed Doubles tennis at the 2012 Summer Olympics.

In the bronze medal match, the United States' Lisa Raymond and Mike Bryan defeated Germany's Sabine Lisicki and Christopher Kas, 6–3, 4–6, [10–4].

The tournament was held from 1 to 5 August on the grass courts of the All England Lawn Tennis and Croquet Club in Wimbledon, London.

This was the first time mixed doubles was included in the Olympic tennis programme since Paris in 1924, where Hazel Wightman and Richard Williams won gold.

The other seeded teams were the two American pairs (with the Bryan brothers playing with Liezel Huber and Lisa Raymond) and Polish duo Agnieszka Radwańska and Marcin Matkowski.
