Great Britain at the 2016 Summer Olympics

Great Britain, or in full Great Britain and Northern Ireland, represented by the British Olympic Association (BOA), the previous host of the 2012 Olympics at London, competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016 and the team of selected athletes was officially known as Team GB. British athletes have appeared in every Summer Olympic Games of the modern era, alongside Australia, France, Greece, and Switzerland, though Great Britain is the only country to have won at least one gold medal at all of them. The team represented the United Kingdom, the three Crown Dependencies, and the thirteen British Overseas Territories, ten of whom sent representatives.

These Games were the most successful for Great Britain since 1908, winning a total of 67 medals, which exceeded its London 2012 tally of 65 medals, therefore becoming the first nation to surpass its medal total at the Olympics immediately following one that it hosted. Great Britain also became one of only two nations (the other being Azerbaijan) ever to increase the number of medals achieved in five consecutive Games. Overall, Great Britain finished second in gold medals behind the United States and third in total medals after the United States and China. The country won gold medals in more sports than any other nation at the Games and topped the medal tables in cycling, sailing, triathlon, golf, and rowing. Great Britain also secured its first-ever golds in golf, diving, and gymnastics, and successfully defended 18 of the gold medals it had won in London.
