The 1985 2. Divisjon was a second-tier football league in Norway. The league consisted of 24 teams, divided into groups A and B. The winners within each group were promoted to the 1986 1. divisjon.[1] The second-place teams of each group met the tenth position finisher in the 1. divisjon in a qualification round, with the winner promoted to 1. divisjon. The bottom three teams of both groups were relegated to the 3. divisjon.
