Baume-les-Messieurs (French pronunciation: ​[bom le mesjø]) is a commune in the Jura department in the region of Bourgogne-Franche-Comté in eastern France. The village lies within the most extensive of the steephead valleys of the Jura escarpment, the Reculée de Baume. It is therefore almost surrounded by limestone cliffs about 200m high. One of the source rivers of the Seille, the Seille de Baume, has its source within the Reculée and flows through the village. A short tributary of the Seille de Baume, the Dard, merges with the Seille at Baume; at the source of the Dard, also within the Reculée, there is a notable series of caves.
