The 2016 Summer Olympics, officially known as the Games of the XXXI Olympiad, and officially branded as Rio 2016, were an international multi-sport event held from 5 to 21 August 2016 in Rio de Janeiro, Brazil, with preliminary events in some sports beginning on 3 August. 11,238 athletes representing 207 National Olympic Committees (NOCs) participated, including first-time entrants Kosovo, South Sudan, and the Refugee Olympic Team. The games featured 306 events in 28 sports and 41 disciplines. The 2016 Summer Games were the first Olympics to be held in South America. Athletes representing 87 NOCs received at least one medal, breaking the record of most NOCs winning a medal at a single edition of the Olympics. Athletes from 59 nations earned gold medals at these games, also breaking the record for the most nations winning gold at a single games. Bahrain, Fiji, Ivory Coast, Jordan, Kosovo, Puerto Rico, Singapore, Tajikistan, and Vietnam won their first Olympic gold medals.

Medals

The 2016 Olympic medals were the largest diameter of any medals presented at the Olympics up to this point. The golds were purer than any presented at all preceding Olympics. The silvers were made from recycling mirrors, solder, and X-ray plates. Just under half of the copper used in the bronze medals was recycled from normal operations at the Brazilian Mint. The reverse of the medals features Nike, the Greek goddess of victory.

The table uses the Olympic medal table sorting method. By default, the table is ordered by the number of gold medals the athletes from a nation have won, where a nation is an entity represented by a NOC. The number of silver medals is taken into consideration next and then the number of bronze medals. If teams are still tied, equal ranking is given and they are listed alphabetically by their IOC country code. Events in boxing result in a bronze medal being awarded to each of the two competitors who lose their semi-final matches, as opposed to fighting in a third place tie breaker. Other combat sports, which include, judo, taekwondo, and wrestling, use a repechage system which also results in two bronze medals being awarded. Two gold medals and no silver medals were awarded due to a first-place tie in the women's 100 metre freestyle swimming event, while three silver medals and no bronze medals were awarded due to a second-place tie in the men's 100 metre butterfly swimming event. Additionally, two bronze medals were awarded for a third-place tie in the women's 100 metre backstroke swimming and in the men's K-1 200 metres canoeing events. Nijat Rahimov of Kazakhstan originally won the gold medal in men's 77 kg weightlifting but was disqualified in March 2022 by the Court of Arbitration for Sport (CAS) for doping violations. As of July 2024, the medals have not yet been re-allocated and will not be until final rulings by the IOC have been issued. Changes in medal standings (see below)
