Andrew ("Andy") Jameson (born 19 February 1965) is an English sports commentator and former competitive swimmer. He competed in three consecutive Summer Olympics, starting in 1980.
Jameson was born in Crosby, Merseyside. His swimming career was initially centred on individual medley events, but after studying at Arizona State University, he decided to specialise in the 100 m butterfly and 100 m freestyle events.
He then won silver in the 100 m butterfly at the 1985 European Championships (Sofia), behind the legendary Michael Groß.
Jameson took bronze in the 100 m butterfly at the 1986 World Championships (Madrid), and then went on to take gold in the same event at the Edinburgh Commonwealth Games later that year.
He won gold at the 1987 European Championships (Strasbourg) in the 100 m butterfly, and was also part of the team which took silver in the 4×100 m medley relay.
Going into the 1988 Summer Olympics in Seoul, he was one of the pre-race favourites to win, having been undefeated for over two years in the 100 m butterfly.
He qualified fastest into the final, where he took bronze in a time of 53.30 s, breaking both the British and Commonwealth records in the process.
Jameson retired from competitive swimming in 1989. He commentates on swimming for the BBC with fellow Olympian Adrian Moorhouse. His sister Helen was also a swimmer, and represented Britain at the 1980 Olympic Games in Moscow winning a silver medal in the 4×100 m medley relay.
He now lives in London with his wife Peggy Jameson and has two children Maisie (1998) and Oscar (2000)
