Meuse (French pronunciation: [møz]) is a department in northeast France, named after the River Meuse. Meuse is part of the current region of Grand Est and is surrounded by the French departments of Ardennes, Marne, Haute-Marne, Vosges, Meurthe-et-Moselle and has a short border with Belgium on the north. Parts of Meuse belong to Parc naturel régional de Lorraine. Front lines in trench warfare during World War I ran varying courses through the department and it hosted an important battle/offensive in 1916 in and around Verdun.
