The Seeweiher is a reservoir north of the village of Waldernbach in the municipality of Mengerskirchen (county of Limburg-Weilburg) in the Westerwald in the German state of Hesse. It impounds the Vöhlerbach, a tributary of the Kallenbach which, in turn, flows into the River Lahn. It has a surface area of 13 hectares.
The Seeweiher was impounded in 1452 and is thus one of the oldest reservoirs in Hesse.
