San Marino 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 thirteenth appearance in the Summer Olympics since its début at the 1960 Summer Olympics. The delegation sent by the Sammarinese National Olympic Committee consisted of four athletes: sprinter Martina Pretelli, archer Emanuele Guidi, trap shooter Alessandra Perilli and short-distance swimmer Clelia Tini.

Three of the four Sammarinese athletes qualified for the Games by using wild cards for their respective events, bar Perilli who made the Olympics by meeting the required criteria for her sport. Although Pretelli, Guidi and Tini were unable to advance beyond the heats of their contests, Perilli came joint second in the final of the women's trap shooting event. Perilli narrowly missed out on claiming San Marino's first Olympic medal after placing fourth following a shoot-out for the bronze and silver medals.
