NOFV-Oberliga
The NOFV- Oberliga is a division at step 5 of the German football league system. After the fall of the Berlin Wall, it became the successor of the DDR-Oberliga, and functions today as a 5th division in the former territory of East Germany and the city of Berlin.
This league is named after the Nordostdeutscher Fußballverband (NOFV - North-East German Football Association), the regional association of the DFB in the former East German territories.
The league is currently split in two groups, north and south, the NOFV-Oberliga Nord and NOFV-Oberliga Süd. A third league, the NOFV-Oberliga Mitte existed from 1991 to 1994.
