Bjørn Rune Gjelsten (born 17 September 1956 in Tomrefjord) is a Norwegian businessman and Offshore powerboat racing World Champion.
In 2004, Gjelsten retired to concentrate on his businesses, and sold the "Spirit of Norway" team to Bård Eker, who won the 2005 Championship with Curtis.
Buying into Wimbledon Football Club in the late 1990s, Gjelsten and his business partner Kjell Inge Røkke became joint owners of the team in 2000.
The following year, with the side homeless since leaving their Plough Lane ground in 1991 and playing at Crystal Palace's Selhurst Park stadium in Croydon, southeast London, Gjelsten, along with Røkke, chairman Charles Koppel and businessman Pete Winkelman agreed to relocate the team to Milton Keynes, a town around 60 miles from their traditional base.
The following season, Wimbledon FC would go on to play in front of record low crowds, including just 664 for a League Cup game against Rotherham, before finally completing the move in 2004, becoming Milton Keynes Dons.
