The Doubs is a 453 km long river in eastern France and western Switzerland, left tributary of the Saône. Its source is near Mouthe in the western Jura mountains. First it flows north-east, more or less along the French-Swiss border (forming the border for approx. 40 km). Near Montbéliard it turns south-west, until it flows into the river Saône in Verdun-sur-le-Doubs, approx. 20 km north-east of Chalon-sur-Saône.

The Doubs flows through the following départements, cantons and cities:

• Doubs (F, named after the river): Pontarlier.
• Canton of Neuchâtel (CH).
• Canton of Jura (CH): Saint-Ursanne.
• Doubs (F): Montbéliard, Besançon.
• Jura (F): Dole.
• Saône-et-Loire (F): Verdun-sur-le-Doubs.

Trbutaries include:

• Loue
• Dessoubre

The river forms several lakes:

• Lac des Brenets (elevation 750 m)
• Lac de Moron (elevation 716 m)
• Lac de Biaufond (elevation 610 m)
