Franche-Comté (French pronunciation: [fʁɑ̃ʃ kɔ̃te]; Franc-Comtois: Fraintche-Comtè; Arpitan: Franche-Comtât) the former "Free County" of Burgundy, as distinct from the neighbouring Duchy, is an administrative region and a traditional province of eastern France. It is composed of the modern departments of Doubs, Jura, Haute-Saône and Territoire de Belfort and has a population of 1,159,000 (2008).

The principal cities are the capital Besançon, Belfort, and Montbéliard (Aire Urbaine Belfort-Montbéliard-Héricourt-Delle). Other important cities are Dole (capital before the region was conquered by Louis XIV in the late 17th century), Vesoul (capital of Haute-Saône), Arbois (the "wine capital" of the Jura), and Lons-le-Saunier (capital of Jura).

The region has been inhabited since the Paleolithic age and was occupied by the Gauls. Little touched by the Germanic migrations, it was part of the territory of the Alamanni in the 5th century, then the Kingdom of Burgundy from 457 to 534. It was Christianized through the influence of St. Columbanus, who founded several monasteries there. In 534, it became part of the Frankish kingdom. In 561 it was included in the Merovingian Kingdom of Burgundy, under Guntram, the third son of Clotaire I. In 613, Clotaire II reunited the Frankish Kingdom under his rule, and the region remained a part of the Kingdom of Burgundy under the later Merovingians and Carolingians.
