Osnabrück Land is a region in southwest Lower Saxony in Germany, which extends into the state of North Rhine-Westphalia. Its centre is the city of Osnabrück. The region is dominated by the Teutoburg Forest and the River Hase. Originally a variant of Low German was spoken here which belonged to the East-Westphalian dialect. The region is generally identified with the district and city of Osnabrück, which largely corresponds to the Prince-Bishopric of Osnabrück in the Holy Roman Empire. The Osnabrück Land Regional Association (Landschaftsverband Osnabrücker Land) looks after cultural issues for the region.
