The Blies is a right tributary of the Saar in southwestern Germany (Saarland) and northeastern France (Moselle). The Blies flows from three springs in the Hunsrück near Selbach, Germany. It is roughly 100 km long, ending in the French city of Sarreguemines. It flows through Sankt Wendel, Ottweiler, Neunkirchen, Bexbach, Homburg and Blieskastel (Blieskastel being named after the river). Its lower extent demarcates part of the Franco–German border. The section within France and on the French-German border is 19.7 km (12.2 mi) long.
