It belongs to the Verbandsgemeinde Simmern-Rheinböllen, whose seat is in Simmern. Wahlbach has some 175 inhabitants.

The municipality lies in the Hunsrück, with the municipal area spread out over several hills, giving it an average elevation of 433 m above sea level. Wahlbach lies some 4 km west of Rheinböllen and the Autobahn A 61. To the south, it is roughly 2 km to Argenthal and to the west a good 4 km to Simmern.

Archaeological finds from barrows bear witness to early habitation. In 1158, Wahlbach had its first documentary mention. The village was a noble family’s namesake, although it died out soon after 1258. Later, the village belonged to Electoral Palatinate “New Court” (neues Gericht), which in 1410 was grouped into the new Duchy of Palatinate-Simmern. In 1556, the duchy introduced the Reformation. In 1673, Wahlbach passed back to Electoral Palatinate and with the occupation of the Rhine’s left bank by French Revolutionary troops in 1794, it became part of France. In 1814 it was assigned to the Kingdom of Prussia at the Congress of Vienna. Since 1946, it has been part of the then newly founded state of Rhineland-Palatinate. In 1961, the Evangelical church was built.

The council is made up of 6 council members, who were elected by majority vote, and the honorary mayor as chairman.

Wahlbach’s mayor is Volker Mayer.
