a town of France, capital of an arrondissement of the same name, in the department of Drome, is situated at the confluence of the Roubion and the Jabron, 26 miles S. of Valence. The town is defended by Gothic walls, is entered by four gates, and has a castle standing on an eminence in the centre. The houses are well built, and the streets broad and paved with basalt. It derives its name, Montel d'Adhemar (Mons Adhemari), from an ancient noble family who had possessions here as early as the time of Charlemagne. Montelimart was one of the first towns of France to adopt the Reformed doctrines; and is noted in the civil wars of the Reformation. It has a court of primary instance, and a communal college. Manufactures of silk, leather, hosiery, tiles, &c., are carried on; and the place is famed for a sort of cake made of almonds and honey. Some trade is carried on in these articles, as well as in cattle, corn, &c. Pop. (1851) 8632.
