Ibbenbürener Bergplatte, Mountain summit in North Rhine-Westphalia, Germany.

The Ibbenbürener Bergplatte is a ridge of Carboniferous rock raised as a horst, reaching 176.1 m, extending 14 km west-northwest and 5 km wide north of Ibbenbüren. Its eastern part, the Schafberg, and western part, the Dickenberg, are separated by the 2 km wide Bockradener Graben. The highest natural point lies near the Blomenkamp transmitter, while a spoil heap northeast of Dickenberg exceeds 190 m.

The mountain formed through geological processes and contains coal deposits from the Carboniferous period around 300 million years ago. Humans later exploited these resources through mining, which shaped the region's economy for centuries.

The name Schafberg is used in mining contexts for the whole Ibbenbürener Bergplatte, while the eastern part is called Ostfeld and the western part Dickenberg, or Westfeld. At the Querenberg between Ibbenbüren and Mettingen, the name is thought to come from the Low German word for a hand mill, Quern: several of these hand millstones were found in 8th-century flat and mound graves in 1932, and a Mühlsteinregal once stood there.

The best views are from the Rudolfshalde, a coal spoil heap of the Ibbenbüren mine that rises above the plateau; on clear days you can see as far as Osnabrück, Rheine and the Emsland nuclear power station near Lingen. The highest natural point, 176.1 m, lies in the Osterledde hamlet, about 90 m southwest of the Blomenkamp transmitter. The plateau stretches 14 km west-northwest and is 5 km wide, with parts inside the TERRA.vita nature and geopark.

The highest point is not natural: a spoil heap northeast of Dickenberg, about 300 m long and 60 m wide, rises above the 190 m contour line, higher than the natural summit at 176.1 m. From the Rudolfshalde coal heap, views reach Osnabrück, Rheine and the Emsland nuclear power station in Lingen.
