Blanche of Navarre, was a French princess and Infanta of Navarre as a member of the House of Évreux and by marriage Queen consort of France from 29 January until 22 August 1350.
Blanche d'Évreux was originally supposed to marry John, Duke of Normandy and heir of the throne of France —whose first wife had just died of the Black Death—, but eventually married his father, King Philip VI of France. Only a few months after their wedding, the French monarch died prematurely and Blanche found herself a widow.
After giving birth in 1351 to a posthumous daughter, Blanche refused to remarry King Peter of Castile and retired to the large dower lands that were granted by her late husband. Despite her widowhood, she played an essential role in 1354 by attempting to reconcile her brother King Charles II of Navarre with King John II of France. In 1389 she organized the coronation of Isabeau of Bavaria, the wife of King Charles VI of France.
