Belize competed at the 2012 Summer Olympics in London, which were held from 27 July to 12 August 2012. The country's participation in London was its eleventh appearance in the Summer Olympics since its debut at the 1968 Summer Olympics. The delegation included two short-distance runners and one judoka: Kenneth Medwood, Kaina Martinez and Eddermys Sanchez. Medwood qualified by recording a time that met qualification standards while the latter two entered through wildcard places. Medwood was selected as the flag bearer for both the opening and closing ceremonies. Medwood reached the semifinals of the men's 400 metres hurdles before he was eliminated from competition while Martinez did not progress farther than the quarterfinal stage of the women's 100 metres. Sanchez was defeated by his opponent Miklós Ungvári of Hungary in a 19-second match in the Round of 32 of the men's half-lightweight judo competition.
