Mark Andrew Foster (born 12 May 1970) is an English former competitive swimmer who represented Great Britain in the Olympics and world championships, and swam for England in the Commonwealth Games.

[14][15][16][17] First selected for the British team in 1985, Foster's breakthrough came in 1990 when he won his first individual international medal - bronze - in the Commonwealth Games in Auckland.

The Race Club included such well known swimmers as Foster, Roland Mark Schoeman, Ryk Neethling, and Therese Alshammar.

[19] Despite success at Commonwealth, European and World championship level mostly at short courses, Olympic titles eluded him and he has never won a medal.

[20] Nonetheless, Foster responded to his omission from the Olympic squad with a gold medal in the World Short Course Championships in Indianapolis later that year.

Although Foster announced his retirement from swimming after the European short course championships in April 2006 at the age of 35, he still occasionally competed that year at invitational meets.

Returning to the British squad he won a silver medal in the 50 m freestyle at the 2008 FINA Short Course World Championships, and qualified to represent Great Britain at the same distance in the Olympics.

In 1999, Foster's friend, Scottish athlete Ross Baillie died from anaphylaxis shortly after the pair had gone out for lunch.

[23] In October 2008, Foster was a celebrity judge for the Miele Fashion Prize, in aid of children's medical charity, Sparks.

[25] Foster is also an ambassador for the UK charity SportsAid, which supported him in the early days of his career, helping talented young sports people to achieve their ambitions.

On 27 July 2012, Foster appeared on a Paralympic special of the Channel 4 game show The Million Pound Drop with Countdown presenter Rachel Riley.

In 2002 Foster lived in Bath, UK, sharing a flat with former 110m hurdles Olympic silver medallist and World champion athlete Colin Jackson.
