See main article: Wrestling at the 2008 Summer Olympics. Men's freestyle 66 kilograms competition at the 2008 Summer Olympics in Beijing, China, was held on August 20 at the China Agricultural University Gymnasium.
This freestyle wrestling competition consisted of a single-elimination tournament, with a repechage used to determine the winner of two bronze medals. The two finalists faced off for gold and silver medals. Each wrestler who lost to one of the two finalists moved into the repechage, culminating in a pair of bronze medal matches featuring the semifinal losers each facing the remaining repechage opponent from their half of the bracket.
Each bout consisted of up to three rounds, lasting two minutes apiece. The wrestler who scored more points in each round was the winner of that round; the bout finished when one wrestler had won two rounds (and thus the match).
