The 1990–91 season of the former DDR-Oberliga, renamed NOFV-Oberliga for this season, was the last season of the top East German league.
After the season, all East German leagues were dissolved and their teams placed in the German football league system. The top two teams joined the Bundesliga, while those ranked third through sixth went to the 2. Bundesliga. The bottom two teams remained in the NOFV-Oberliga, which absorbed all but the relegated teams of the former East German second tier DDR-Liga (also renamed NOFV-Liga) and joined the German league system at the third tier. The seventh through twelfth placed teams were drawn into a playoff with the two NOFV-Liga group champions for two additional 2. Bundesliga places, with unsuccessful teams also remaining in the NOFV-Oberliga.
The competition was contested by 14 teams. Hansa Rostock won the championship and Dynamo Dresden came in second, thus claiming the other available qualification for the Bundesliga. A total of 8 Eastern teams remained professional into both two national German championships.
