Duncan William MacNaughton Scott is a Scottish swimmer representing Great Britain at the FINA World Aquatics Championships, LEN European Aquatics Championships, European Games and the Olympic Games, and Scotland at the Commonwealth Games. Scott made history after winning four medals - more than any other British athlete at a single Olympic Games - in Tokyo 2020, simultaneously becoming Great Britain's most decorated swimmer in Olympic history. With an additional gold and silver medal in Paris 2024 bringing his total to eight, Scott became Scotland's most-decorated Olympian, and is currently tied with Bradley Wiggins as the second most-decorated Olympian in British history. Scott is the only athlete in the top three to still be actively competing, and the only member of the top four who is not a track cyclist.
