James Wilby (swimmer)

James Wilby (born 12 November 1993) is a British competitive swimmer who specialises in the breaststroke. Wilby is the 2018 Commonwealth Games champion in 200 metre breaststroke, the 2022 Commonwealth Games champion in 100 metre breaststroke, and the 2022 European champion in 200 metre breaststroke. He formed part of the Great Britain team that won World Championship gold in the men's 4 x 100 metre medley relay in 2019, and the England team that won the Commonwealth Games Men's 4 x 100 metre medley relay in 2014 and 2022.

He has represented Great Britain at the Olympic Games, winning a silver in the 2020 Summer Olympics as a heat swimmer in the men's 4 x 100 metre medley relay, three FINA World Aquatics Championships, winning a further silver in the 100m breaststroke, and two bronze medals, and England at three Commonwealth Games, where he has won four other medals aside from his four gold medals.

Wilby's career has overlapped those of several other internationally significant British breaststrokers, notably Olympic and Commonwealth medalist Michael Jamieson, Commonwealth and European champion Ross Murdoch and multiple Olympic and World champion Adam Peaty. In 2022 Wilby became the first swimmer to defeat Peaty in an international 100 metres breaststroke race since Peaty first won the World title, claiming the Commonwealth gold medal in the event in Birmingham in 2022. Weeks later, he won his first individual European title in the 200 metres breaststroke.
