Ardeche, a S. E. department of France, bounded E. by the Rhone; area, 2,134 sq. m.; pop. in 1872. 380.277. The river Ardeche, from which it has its name, rises near its centre and flows S. S. E. to the Rhone. The Loire has its source near that of the Ardeche, and flows in the opposite direction. A large portion of the surface is occupied by branches of the Cevennes mountains. The department is rich in iron and coal, but deficient in agricultural products, though potatoes are largely raised, chestnuts are plentiful in the forests, and the pasturage is fine. Wine, silk, and wool are among the principal exports, as well as various manufactured goods, including famous stationery. Privas is the capital, and the other chief towns are Annonay and Aubenas. The department is divided into the three arrondissements of Privas, Largentierel and Tournon.
