Doubs (/duː/, doo; French: [du] ⓘ; Arpitan: Dubs) is a department in the Bourgogne-Franche-Comté region in Eastern France.

Many famous people, including Mirabeau, Toussaint Louverture and Heinrich von Kleist, were imprisoned in the Château de Joux.

However, the commune of Le Cerneux-Péquignot was annexed by the Canton of Neuchâtel under the terms of the 1814 Treaty of Paris, and since remained Swiss territory.

Between the defeat of France at the Battle of Waterloo and November 1818, Doubs was included in the area occupied by Austrian troops.

Victor Hugo, Gustave Courbet, Armand Peugeot, Auguste and Louis Lumière and Frank Darabont are among the famous people born in Doubs.
