The Kermeter is an upland region, up to 527.8 m above sea level (NN), which is part of the North Eifel in the districts of Aachen, Düren and Euskirchen in the southwestern part of the state of North Rhine-Westphalia in Germany.
The Kermeter ridge is covered by a forest, some 33 km² in area, that is one of the largest contiguous, deciduous forests in the Rhineland. Since 1 January 2004 it has formed the core zone of the Eifel National Park.
The Kermeter lies on the territory of the three Eifel parishes of Heimbach, Simmerath and Schleiden. It is bordered to the north and west by the Rur Reservoir (around 281.5 m above NN) and thus by the Rur valley near Heimbach, to the southwest by the Obersee (a pre-basin of the Rur Dam), and in the south by the Urft Reservoir (at around 322.5 m above NN) and thus the Urft valley. In the southwest the Kermeter transitions into Wolfgarten and Gemünd in the direction of the upper reaches of the Rotbach.
The highest point in the Kermeter is an unnamed rounded summit (527.8 m above NN) near Wolfgarten, on which the fire service and observation tower, the Wolfgarten Fire Watchtower (Feuerwachtturm Wolfgarten), stands (a list of other Kermeter hills is given below).
