Ørjan Berg (born 20 August 1968 in Bodø) is a former Norwegian football midfielder, who most recently played for Rosenborg. He retired at the end of the 2006 season, and has previously played for F.K. Bodø/Glimt, FC Wettingen, TSV 1860 München, and FC Basel. Ørjan is the brother of Bodø/Glimt player Runar Berg, and the son of legendary Bodø/Glimt midfielder and playmaker Harald Berg.
He is the current sporting director of Bodø/Glimt.
He is married and has two sons, Patrick and Marius.
Berg first played — as his father had — at Bodø/Glimt, then playing in the 2nd division, later moving up to the 1st. In 1988 Rosenborg coach Nils Arne Eggen brought him and his friend Jahn Ivar "Mini" Jakobsen from Bodø/Glimt to Rosenborg, where they won the double in their debut year in the Norwegian top division.
After two seasons at Rosenborg, Berg was sold to Swiss club Wettingen FC in 1990, where he played for one season before moving to 1860 Munich and FC Basel before returning to his home club Bodø/Glimt in 1996.
In Bodø/Glimt, now back in the top division, Berg played for three seasons losing a cup final against Tromsø I.L. in 1996. In 1999 Rosenborg needed to strengthen its team to play in the UEFA Champions League, and Berg went on loan to Rosenborg. Later that year he was traded to Rosenborg.
In mid season 2006, he returned to his home town Bodø, trying to recover from injuries which has plagued him in the last (almost) two years. If he recovered, he said he would join Rosenborg again when preseason starts at the beginning of 2007 – which would have been his last season according to his contract. However, it became increasingly clear that his injury would never be completely healed, and he decided to terminate his contract a year early. His official farewell ceremony took place in the recess of the Rosenborg – Viking match on 29 October.
Berg made his debut for the Norwegian national team in 1988, but after Egil Olsen became coach Berg was rarely found good enough for the squad. He got a second chance when Norway got Nils Johan Semb as coach in 1998 and Berg played on the national team again 10 years after his debut. He earned a total of 19 caps, scoring 1 goal. His last international match was a February 2000 friendly match against Sweden. In 2002, Berg declared that he retired from the national team.
