Lachaussée (in French pronounced as /laʃose/) is a commune in the Meuse department in Grand Est in north-eastern France.
The village of Lachaussée lies on the south-eastern rim of a huge pond named Étang de Lachaussée, which was created during the Middle Ages from a marsh area and then devoted to pisciculture.
