Stahlhofen am Wiesensee is an Ortsgemeinde – a community belonging to a Verbandsgemeinde – in the Westerwaldkreis in Rhineland-Palatinate, Germany. It is not to be confused with Stahlhofen, another community in the same district, but in the Verbandsgemeinde of Montabaur.
Stahlhofen am Wiesensee lies 3 km northeast of Westerburg, on a bank near the Wiesensee's west shore. Since 1972 it has belonged to what was then the newly founded Verbandsgemeinde of Westerburg, a kind of collective municipality. Its seat is in the like-named town.
Stahlhofen am Wiesensee's neighbours are Pottum, Hergenroth, Winnen and Halbs.
The municipal council is made up of 9 council members, including the extraofficial mayor (Bürgermeister), who were elected in a majority vote in a municipal election on 13 June 2004.
The old village school from 1830 is a protected monument.
The Wiesensee (lake) has an area of roughly 80 ha and offers not only hikes around it but also bathing, sailing, surfing and angling. Near the lake is also found a golf course.
North of the community runs Bundesstraße 255, linking Montabaur and Herborn. The nearest Autobahn interchange is Montabaur on the A 3 (Cologne - Frankfurt), some 20 km away. The nearest InterCityExpress stop is the railway station at Montabaur on the Cologne-Frankfurt high-speed rail line.
