Basketball at the 2016 Summer Olympics
Basketball at the 2016 Summer Olympics was the nineteenth appearance of the sport of basketball as an official Olympic medal event. It took place at Rio de Janeiro, Brazil, and was held from 6 August to 21 August 2016. The preliminary and knockout round matches for men were played inside the Carioca Arena 1 in Olympic Park which seated up to 16,000 spectators. The matches for women were played at the Youth Arena. This marked the first time that the men's and women's Olympic tournaments were played in multiple/separate venues. The  host country Brazil failed to make it to the quarterfinals, of both the men's and women's tournaments, after being eliminated from the group stage. Three countries in both categories took all of the medals: The United States (who took both gold medals), Serbia, and Spain. Venues. Carioca Arena 1, the largest among the three Carioca Arenas, and Youth Arena, are the arenas that are being used for the basketball tournaments. The Ginásio do Maracanãzinho, site of the 1954 FIBA World Championship and the 1963 FIBA World Championship, hosted the indoor volleyball tournaments instead. Carioca Arena 1 hosted the  entire men's tournament and the women's knockout stage, while Youth Arena hosted the women's preliminary round. Qualification. The National Olympic Committees might enter up to one 12-player men's team and up to one 12-player women's team. Hosts. Just as in 2012, the Olympic hosts were not guaranteed an Olympic berth.
