The 1991 Tippeligaen was the 47th completed season of top division football in Norway.

The winners of the two groups of the 1. divisjon are promoted, as well as the winner of a series of play-off matches between the two second placed teams in the two groups of the 1. divisjon and number ten in the Tippeligaen.

The season ended on October 13, 1991, with Viking claiming their eighth league title.

Viking were thus the last club to win the league before Rosenborg's 13-year domination started.
