Indonesia competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. This was the nation's fifteenth appearance at the Summer Olympics.

During the Parade of Nations within the Rio de Janeiro 2016 Summer Olympics opening ceremony, athletes and officials from each participating team marched in the Maracanã Stadium preceded by their flag and placard bearer. Each flag bearer had been chosen either by the team's National Olympic Committee or by the athletes themselves.
