Nicaragua competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. This was the nation's thirteenth appearance at the Summer Olympics, with the exception of the 1988 Summer Olympics in Seoul because of its partial support to the North Korean boycott.

Nicaragua Olympic Committee (Spanish: Comité Olímpico Nicaragüense) sent the nation's smallest delegation to the Games since 2004. A total of five athletes, three men and two women, were selected to the Nicaraguan team across four different sports.^[2] Majority of Nicaraguan athletes made their Olympic debut in Rio de Janeiro, except for butterfly swimmer Dalia Torrez Zamora, who attended her third Games as the oldest (aged 26) and most experienced competitor.
