Mauritania competed at the 2012 Summer Olympics in London, which was held from 27 July to 12 August 2012. The country's participation at London marked its eighth appearance in the Summer Olympics since its debut in the 1984 Summer Olympics. The delegation included two track and field athletes, Jidou El Moctar and Aicha Fall, who were selected to the team by wildcard places, as the nation had no athletes that met either the "A" or "B" qualifying standards. Moctar was selected as flag bearer for the opening ceremony while a LOCOG Games Maker carried it for the closing ceremony. Neither of the two athletes progressed beyond the heats.
