Jørgen Marcussen (born 15 May 1950) is a former Danish racing cyclist.
He competed, as an amateur, in the individual road race and team time trial events at the 1972 Summer Olympics.[1]As an amateur he also became national champion in team time trial in 1970, and in individual time trial in 1975.[2]
From 1976 he rode as a professional, predominantly on less prominent teams.
In the 1978 UCI Road World Championships Jørgen Marcussen created an upset by winning a bronze medal,[3] behind Gerrie Knetemann and Francesco Moser. He also managed to finish 4th overall in the 1981 Vuelta a España,[4] which was the best result by a Dane in a Grand tour at the time. It was a feat that was not expected and not surpassed until Bjarne Riis came 3rd in the 1995 Tour de France.
Jørgen Marcussen is married to Olympic cyclist Karina Skibby.
