The Gambia 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 début at the 1984 Summer Olympics. The delegation included two athletes, Suwaibou Sanneh and Saruba Colley, the former had qualified by setting a qualifying time that fell within the required standard and the latter entered via a wildcard place. Sanneh was selected as the flag bearer for both the opening and closing ceremonies. Sanneh became the first Gambian athlete to advance into the semi-finals of the men's 100 metres, while Colley was eliminated after the quarter-final stages of the Women's 100 metres.
The Gambia participated in eight Summer Olympic Games between its début at the 1984 Summer Olympics in Los Angeles, United States and the 2012 Summer Olympics in London, England. The highest number of athletes sent by Gambia to a summer Games is ten to the 1984 Summer Olympics. No Gambian athlete has ever won a medal at the Olympics. The Gambia participated in the London Summer Olympics from 27 July to 12 August 2012. The Gambia National Olympic Committee (NOC) selected two athletes via qualification standards. An NOC would be able to enter up to three qualified athletes in each individual event as long as each athlete met the "A" standard, or one athlete per event if they met the "B" standard.
The two athletes that were selected to compete in the London Games were Suwaibou Sanneh in the men's 100 metres and Saruba Colley in the women's 100 metres. Sanneh was the flag bearer for both the opening and closing ceremonies. The athletes were due to train in York at various facilities in the city, including the Huntingdon athletics stadium and the University of York but withdrew due to financial issues. Along with the two athletes, a delegation led by the Gambia National Olympic Committee president Momodou Demba attended the London Games. The delegation consisted of Beatrice Allen, the vice-president, secretary general Peter Prom and treasurer Ousman Wadda.
Suwaibou Sanneh was the only male athlete representing The Gambia at the London Olympics. He previously competed in the 2008 Olympic Games in Beijing, China. Sanneh qualified for the London Olympics by securing the required qualifying time in the 'B' standard in an event in Jamaica. He competed in the men's 100 metres race on 4 August in the third heat of the quarter-finals, finishing fifth out of eight athletes with a time of 10.21 seconds. Sanneh became the first Gambian athlete to qualify for the semi-finals of the event, and the second time a competitor from the country advanced into the semi-finals of any Olympic event. He ranked ahead of Rytis Sakalauskas from Lithuania (10.29 seconds), Central Africa's Béranger-Aymard Bossé (10.55 seconds) and Bruno Rojas of Bolivia (10.65 seconds) in a heat led by American sprinter Ryan Bailey (9.88 seconds). In the semi-finals on 5 August, Sanneh achieved a Gambian national record of 10.18 seconds, but did not advance into the final after finishing eighth (and last) in her heat.
Competing at her first Summer Olympics, Saruba Colley qualified for the London Games as a wildcard, as her best time for the 100 metres event, 12.37 seconds, set in the 2010 Commonwealth Games in New Delhi, was nearly one second slower than the "B" qualifying standard. She competed in the preliminary round on 3 August and was drawn in the fourth heat. Colley finished second with a time of 12.21 seconds, behind heat winner Toea Wisil from Papua New Guinea (11.60 seconds). The result ensured she advanced into the quarter-finals of the event. Colley was placed in heat three along with seven other athletes. She posted a time of 12.06 seconds, finishing eighth and setting a national record in the process. Colley ranked behind Colombian athlete Yomara Hinestroza (11.56 seconds) in a heat led by eventual bronze medallist Veronica Campbell-Brown of Jamaica (10.94 seconds) and Bulgaria's Ivet Lalova (11.06 seconds). She finished 55th out of 56 athletes overall and did not advance to the later rounds.
