1991 DFB-Supercup

The 1991 DFB-Supercup was the fifth edition of the DFB-Supercup. Uniquely, because Germany had just been reunified, the competition featured four teams instead of the usual two: The previous season's Bundesliga and DFB-Pokal winners, 1. FC Kaiserslautern and Werder Bremen, respectively, were joined by their counterparts from the East. Hansa Rostock had won both the NOFV-Oberliga and the NOFV-Pokal, so the losing cup finalists, Stahl Eisenhüttenstadt, took the fourth place in the competition.

Both Western teams advanced to the final, with Kaiserslautern defeating Werder Bremen 3–1 in the final in Hanover.
