Montbard (population 7900 in 1991) is a town in eastern France, a sub-prefecture of the Côte d'Or département, in the Burgundy région.

Montbard is a small industrial town on the river Brenne. The Chateau was the scene of the marriage of Anne de Bourgogne and John of Lancaster, Duke of Bedford in 1423. It was acquired by Georges-Louis Leclerc, Comte de Buffon.

Montbard was the birthplace of Buffon's collaborator Louis-Jean-Marie Daubenton, and where Géneral Jean-Andoche Junot, Duc d'Abrantès (1771-1813), committed suicide.
