Martigny-les-Bains (French pronunciation: [maʁtiɲi le bɛ̃] ⓘ) is a commune in the Vosges department in Grand Est in northeastern France.

The commune includes within its confines the sources of the Anger and Mouzon rivers which set off in opposite directions before they connect between Pompierre and Circourt after about thirty kilometres (nineteen miles).

The valley of the Mouzon, which sets off in a westerly direction before turning to the north, flows over relatively flat plateau land rather than in some form of a gorge: claims appropriate to a spa village are made for the health giving properties of the air here.

Following the successive wars against France that characterised the seventeenth century, the village consisted of two parts, namely Martigny-Saint-Remy and Martigny-Saint-Pierre.

The nearby village of Saint-Pierre had been destroyed by the Swedes who were in the pay of the French king at this time: the inhabitants turned up as refugees in Martigny-Saint-Remy and constructed the quarter which became known as Martigny-Saint-Pierre, including a church of which the remains survived until recently.
