a river of Germany, a left-bank tributary of the Rhine, rises near Selbach in the Oldenburg principality of Birkenfeld. For some distance it forms the boundary between the Bavarian Palatinate and the Prussian Rhine Province, and it falls into the Rhine at Bingen. Its length is 78 m., but it is too shallow and rocky to be navigable. Its picturesque valley, through which runs the railway from Bingerbriick to Neunkirchen, is largely visited by tourists.
