Kœur-la-Petite (in French pronounced as /kœʁ la pətit/) is a commune in the Meuse department in Grand Est in north-eastern France.
In 1463, during the Wars of the Roses, Kœur became a refuge for members of the defeated House of Lancaster. Henry VI of England's wife, Margaret of Anjou found shelter and lived there with her son Edward of Westminster, Prince of Wales, and John Fortescue.
