Lotterberg is a 305 m high hill between the villages of Wolfershausen and Deute in Schwalm-Eder-Kreis, Hesse, Germany.
The hill is composed of basalt that fills the neck of a now-extinct volcano. The volcanic activity was during the Miocene, that is it started 20 million years ago and ended 7 million years ago. This volcano was one of many in the West Hesse Depression. The alkali basalt has a silica volume percentage of 45–55%. The main minerals in the rock are plagioclase, augite and olivine.
On the west side of the Lotterberg is a deposit of loess, which formed after the last Quaternary glaciation.
