Nußbach lies in the valley of the like-named brook, the Nußbach ("Nutbrook"), which empties into the Odenbach some two kilometres downstream from the village, in the North Palatine Uplands.
Nußbach is a clump village lying on a broadening of the dale in the area of the so-called Dorfbach ("Village Brook"), which ﬂows by from the Roßberg ("Steed Mountain") and here empties into the Nußbach.
