The Üßbach is a stream, just under 49 km (30 mi) long in the Eifel in the German state of Rhineland-Palatinate. It rises near Mosbruch in the county of Vulkaneifel and empties near Alf (Cochem-Zell) into the eponymous river, just before the Alf discharges into the river Moselle. The spa resort of Bad Bertrich lies on the Üßbach.
