The 2015 season was Strømsgodset's 9th season in Tippeligaen following their promotion back to the top flight in 2006. David Nielsen started the season as the manager, but was sacked after league round 10, having only secured 12 points. He was replaced by assistant manager Bjørn Petter Ingebretsen on 26 May 2015. Ingebretsen achieved immediate success, and took the team from 9th to 2nd after a 20-match run that secured 45 points.
