The Ravensberg is a 659 m high mountain in the South Harz mountains in the German state of Lower Saxony. It is relatively isolated and visible for a long way. It lies in the district of Göttingen, north of Bad Sachsa.
The mountain top is crowned with a prominent 64 m high tower, which was built in 1970. This tower acted as a listening post during the Cold War; today it is used by Deutsche Telekom.
The Ravensberg is a wonderful viewing point, and is also very easy to get to by car, a road about 3.5 km long, running up to the summit from Bad Sachsa. There is an old boundary stone, the Dreiherrenstein, on this road shortly before the summit.
