The Allaine (French: l'Allaine (f), in its lower course l'Allan (m)) is a 65 km long river in northwestern Switzerland and eastern France. Its source is above the village Charmoille, in the Swiss Jura mountains. Downstream from its confluence with the Bourbeuse and the Canal du Rhône au Rhin, near Méziré, it is called the Allan. It is a right tributary of the Doubs, which it joins a few km downstream from Montbéliard, where it takes the Savoureuse with it, a river with its sources in the southern Vosges.
