Nicholas Gillingham, MBE (born 22 January 1967) is an English former competitive swimmer who represented Great Britain in the Olympics, FINA world championships and European championships, and England in the Commonwealth Games. Gillingham participated in three consecutive Summer Olympics, starting in 1988. In August 1989, he equalled the existing world record in the long-course 200-metre breaststroke, only to co-hold it for a single day before the other record co-holder, American Mike Barrowman, lowered the record again. At the 1988 Summer Olympics in Seoul, he won the silver medal in the 200-metre breaststroke, followed by a bronze one in the same event, four years later in the 1992 Summer Olympics in Barcelona.
Gillingham was awarded the MBE in 1993 for ‘services to swimming’ and retired from full-time competitive sport in 1996. After retiring, he established a sports communications business focusing on sports marketing, development & events.
Recently, Gillingham took part in a scheme called Young Ambassadors, promoting youth sport development in the North East of England at Loughborough.
