Adenbach is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Kusel district in Rhineland-Palatinate, Germany. It belongs to the Verbandsgemeinde Lauterecken-Wolfstein.
The municipality lies in the Odenbach valley in the North Palatine Uplands in the Western Palatinate.
The municipal area measures 294 ha, of which 20 ha is wooded and 10 ha is settled.
Adenbach borders in the northwest and north on the municipality of Odenbach, in the east and southeast on the municipality of Becherbach, in the south on the municipality of Ginsweiler and in the southwest on the municipality of Cronenberg.
Adenbach's Ortsteile are the main village site, also called Adenbach, and the outlying homesteads of Brühlerhof, Langwiesenhof, Bornweiderhof and Brucherhof.
On the east side of the north-south thoroughfare, the houses stand cheek by jowl, forming here and on several sidestreets a small clump village. The new building area west of the village centre, though, is marked by looser construction along a street that runs beyond the brook, parallel to the thoroughfare. The Aussiedlerhöfe – the farming homesteads mentioned as outlying Ortsteile above – lie in the south of the municipal area. A new graveyard was established in 1988 on the brook’s left bank.
