Cote-D'Or, an E. department of France, in Burgundy, bordering on the departments of Aube, Haute-Marne, Haute-Saonc, Jura, Saone-et-Loire, Nievre, and Yonne; area, 3,383 sq. m.; pop. in 1872, 374,510. A chain of hills, the Cote d'Or, crosses the department from S. W. to N. E., forming with the Vosges the watershed between the valleys of the Seine and Saone. In the S. W. is the eastern portion of the hill range known as Mont de Morvan. The rivers are numerous, but small, the Saone being the only one that is navigable. The Burgundy canal passes through the department from N. W. to S. E., uniting the river Yonne with the Saone. Most of the land is fertile, and well adapted to hemp, flax, and various kinds of fruit and grain. The culture of the vine is one of the principal employments. The Cote de Nuits and Cote Beaunoise, E. slopes of the Cote d'Or, are famous for their wines, the former producing the red wines, Romanee, Chambertin, and Nuits; the latter both red and white of unsurpassed quality. Large quantities of honey are obtained. A considerable portion of the country is occupied by forests of oak, beech, elm, etc. The mineral productions are iron, coal, marble, limestone, potters' clay, and several varieties of stone useful for building and for lithography.

The iron mines are chiefly in the N. E. mountains, and are among the most productive in France. Large quantities of charcoal are consumed in the manufacture of malleable iron and steel at the furnaces and founderies near the mines. Other manufactures are linen, woollen, cotton, beetroot sugar, leather, and earthenware. The department is divided into the arrondissements of Dijon, Beaune, Chatillon-sur-Seine, and Se-mur. Capital, Dijon.
