Oldenburg Land (German: Oldenburger Land) is a region and regional association in the German state of Lower Saxony in the area of the former Grand Duchy of Oldenburg (1815–1918), the later Free State of Oldenburg (1918–1946) and administrative district of Oldenburg (1946 to 1978), without its exclaves, along the rivers Hunte and Hase. In the region between coastline, Dümmer and Damme Hills some of the population still speak Low German today and, in Saterland also Saterland Frisian. The region is rich in old Lower Saxon customs such as Schützenfests or Kohlfahrten. Typical country sports include Klootschießen and Boßeln.
The mainly Catholic southern part of the Oldenburg Land is known as Oldenburg Münsterland, the mainly Lutheran northern part is known as Oldenburg Land (Old Oldenburg) in its narrower sense.
