The men's 68 kg competition at the 2016 Summer Olympics was held on 18 August, at the Carioca Arena 3.
The main bracket consisted of a single elimination tournament, culminating in the gold medal match. The top eight athletes in each event were seeded so as not to face each other in the preliminary round. The remainder of the qualified athletes were drawn randomly on 15 August 2016. Two bronze medals were awarded at the Taekwondo competitions. A repechage was used to determine the bronze medal winners. Every competitor who lost to one of the two finalists competed in the repechage, another single-elimination competition. Each semifinal loser faced the last remaining repechage competitor from the opposite half of the bracket in a bronze medal match.[1]
