Vosges (Ger. Vogesen Or Wasgau), a chain of mountains in N. E. France and the German Reichsland of Alsace-Lorraine, forming a continuation of the Jura chain. They separate the Rhine from its W. affluent the Moselle, run N. along the borders of Alsace on the east, and of the French departments of Haute-Saōnie, Vosges, and Meurthe-et-Moselle, and of German Lorraine on the west, forming the W. boundary of part of the basin of the Rhine, the corresponding E. boundary being formed by the Black Forest. The Hardt in Rhenish Bavaria is a N. prolongation of the chain, and the Faucilles connect it with the plateau of Langres and the Cote d'Or in the southwest. The rivers Moselle, Meurthe, Saar, 111, and Ognon have their sources in these mountains. The average height is from 3,000 to 4,000 ft., and the rounded tops, covered with snow for several months, are called balloons, the principal being the Ballon de Guebviller (Gebweiler), nearly 4,700 ft. high, Ballon d'Alsace, and Ballon de Servance. The mountains are generally divided into the upper, central, and lower Vosges. They are well wooded, and have mines of iron, lead, rock salt, and especially copper, and numerous mineral and thermal springs.

Goitre and cretinism are prevalent.
