Kadenbach is an Ortsgemeinde – a community belonging to a Verbandsgemeinde – in the Westerwaldkreis in Rhineland-Palatinate, Germany.
The community lies in the Westerwald between Montabaur and Koblenz in the Nassau Nature Park. The community belongs to the Verbandsgemeinde of Montabaur, a kind of collective municipality.
In 1110, Kadenbach had its first documentary mention.
The council is made up of 17 council members, including the extraofficial mayor (Bürgermeister), who were elected in a municipal election on 13 June 2004.
The community’s arms recalls, with the cross pattée resembling the Teutonic Knights’ cross and the black eagle’s head as part of the whole, the community’s almost 600-year allegiance to the Koblenz House of the Teutonic Knights. The red cross and the tincture silver stand for the overlordship of the Electorate of Trier.
In 2006, a new credit union was built.
The nearest Autobahn interchange is Montabaur on the A 3 (Cologne–Frankfurt), some 12 km away.
