Lesotho at the 2016 Summer Olympics

Lesotho competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. This was the nation's eleventh appearance at the Summer Olympics, except the 1976 Summer Olympics in Montreal, because of its partial support to the African boycott.

Lesotho National Olympic Committee sent the nation's largest delegation to the Games since 1996. A total of eight athletes, seven men and one woman, were selected to the Lesotho team to compete only in athletics, boxing, and mountain biking (the nation's Olympic sporting debut in Rio de Janeiro). Track sprinter Mosito Lehata led the Lesotho delegation as the lone returning Olympian from London 2012 and the nation's flag bearer in the opening ceremony. Lesotho, however, has yet to win its first ever Olympic medal.
