Laos at the 2016 Summer Olympics

Laos, officially the Lao People's Democratic Republic, competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. This was the nation's ninth appearance at the Summer Olympics, having attended all games since 1980 with the exception of the 1984 Summer Olympics in Los Angeles, because of the Soviet boycott.

Six athletes, four men and two women, were selected to the Laotian team through universality places and Tripartite Commission invitations across four sports, without having qualified. Apart from athletics and swimming, Laos marked its Olympic debut in road cycling and judo. Among the Laotian athletes were London 2012 Olympians Laenly Phoutthavong (women's 100 m) in track and field and Santisouk Inthavong (men's 50 m freestyle) in swimming, professional road cyclist Ariya Phounsavath, and hurdler Xaysa Anousone, who led the delegation as the nation's flag bearer in the opening ceremony. Laos has yet to win its first Olympic medal.
