(anciently Noviomagus), a town of France, department of Oise, on the Vorse, a tributary of the Oise, 42 miles E.N.E. of Beauvais. The town is ancient, but well built; and is surrounded with numerous gardens. It was formed into a bishopric in 531; and its cathedral is a fine Romanesque edifice of the twelfth and thirteenth centuries. Charlemagne resided here; and Hugh Capet was here elected king of France in 987. Noyon is, however, chiefly remarkable as the birth-place of the Reformer John Calvin. Manufactures of linens, hosiery, leather, &c., are carried on, and a brisk general trade. Pop. 6322.
