Mont-Terrible was one of the 130 departments of Napoleonic France, with its capital at Porrentruy.
The Mont Terrible for which the department was named is now known as mont Terri, a peak of 804 metres near Courgenay. Mont Terri is now in the canton of Jura, Switzerland.
The department was created in 1793 with the annexation of the short-lived Rauracian Republic, which had been created in December 1792 from a part of the Prince-Bishopric of Basel. In 1797, the old principality of Montbéliard, formerly given to Haute-Saône, was reattached to Mont-Terrible. The department was abolished in 1800. Its territory was annexed to the Haut-Rhin, within which it formed the two arrondissements of Delémont and Porrentruy. In 1815, the territory that had previously formed Mont-Terrible was partitioned between Doubs (Montbéliard) and the Swiss canton of Bern (now forming the canton of Jura and the Bernese Jura).
