The 1990–91 season of the DDR-Oberliga, now renamed NOFV-Oberliga, was the last season of the DDR-Oberliga. After the season the league was dissolved and the clubs integrated into the German football league system. Depending on their performance in the 1990–91 season the clubs would join either the Bundesliga, the 2. Bundesliga, or the Oberliga for the following season.
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.

Dissolution of the Oberliga
After the 1990–91 season, the DDR-Oberliga was dissolved, in context with German reunification. The teams were moved to the leagues in West Germany as follows: the top two teams joined the Fußball-Bundesliga and teams on ranks 3 to 6 joined the 2. Fußball-Bundesliga. The teams ranked 7th to 12th took part in a play-off for two additional 2nd Bundesliga spots. In addition the winners of the two NOFV-Liga (the former DDR-Liga) divisions took part. Play-off losers and the bottom three teams were moved to the NOFV-Oberliga.
