The 2016 Summer Olympics (Portuguese:Jogos Olímpicos de Verão de 2016),^[a]officially known as the Games of the XXXI Olympiad and branded and commonly known as Rio 2016, was a major international multi-sport event held in Rio de Janeiro, Brazil, from 5 August to 21 August 2016.

More than 11,000 athletes from 207 National Olympic Committees, including first time entrants Kosovo, South Sudan, and theRefugee Olympic Team, took part.^[1][2] With 306 sets of medals, the games featured 28Olympic sports, including rugby sevens andgolf, which were added to the Olympic program in 2009. These sporting events took place at 33 venues in the host city, and at five in São Paulo, Belo Horizonte, Salvador,Brasília, and Manaus.

These were the first Summer Olympic Games under the IOC presidency of Thomas Bach.^[2]The host city Rio de Janeiro was announced at the 121st IOC Session in Copenhagen,Denmark, on 2 October 2009. Rio became the first South American city to host the Summer Olympics. These were the first games to be held in a Portuguese-speaking country, the first to be held entirely in the host country's winter, the first since 1968 to be held in Latin America, and the first since 2000 to be held in the Southern Hemisphere.^[3]

The lead-up to these Games was marked bycontroversies, including the instability of the country's federal government; health and safety concerns surrounding the Zika virusand significant pollution in the Guanabara Bay; and a doping scandal involving Russia, which has affected the participation of its athletes in the Games.

The United States topped the medal table for the fifth time in the past six Summer Olympics, winning the most golds (46) and most medals overall (121). Great Britainfinished second and became the first country in the history of the modern Olympics to increase its tally of medals in the subsequent games after being the host nation. Chinafinished third. Host country Brazil won seven gold medals, its most at any single Summer Olympics, finishing in thirteenth place. This year's Olympics also saw the first gold medal winners for Fiji, Kosovo, Puerto Rico, Singapore, Tajikistan, Vietnam and Independent Olympic Athletes (from Kuwait), and 1,000th Olympic gold medal for the United States.
