The 2015 Norwegian Football Cup was the 110th season of the Norwegian annual knock-out football tournament. It began with qualification matches in March 2015. The first round was played 21, 22 and 23 April 2015 and the tournament was ended with the final being held on 22 November 2015.
The victory would have earned Rosenborg a place in the second qualifying round of the 2016–17 UEFA Europa League, but since the club already had qualified to the 2016–17 UEFA Champions League as winners of the 2015 Tippeligaen, this berth was passed down to Odd, fourth-place fininshers in the league.
