The Großer Kellenberg is a hill, sea level (NHN), in the Wiehen range in northern Germany. It is exactly the same height as the hill, known as the Schwarzer Brink, which stands opposite the Großer Kellenberg on the Egge, a parallel side ridge of the Wiehen. The Großer Kellenberg lies within the county of Osnabrück, on the territory of the town of Melle, and thus in the Lower Saxon part of the range. The state border with North Rhine-Westphalia runs one kilometre to the east of the summit.
