Steffenberg is a municipality in Marburg-Biedenkopf district in Hesse, Germany.

Steffenberg lies at the southern foothills of the Rothaargebirge between the towns of Dillenburg (20 km) and Marburg (35 km).

Steffenberg borders in the north on the community of Breidenbach, in the east on the community of Dautphetal, in the south on the communities of Bad Endbach and Angelburg (all in Marburg-Biedenkopf), and in the west on the community of Eschenburg (Lahn-Dill-Kreis).

The community consists of the following six centres:

• Niedereisenhausen
• Oberhörlen
• Quotshausen
• Steinperf
• Obereisenhausen
• Niederhörlen

On 1 April 1972, the formerly independent communities of Niedereisenhausen, Obereisenhausen, Niederhörlen and Oberhörlen joined together of their own free will into the community of Steffenberg. On 1 July 1974, the communities of Steinperf and Quotshausen were amalgamated by state law with Steffenberg to form the current greater community.
