Marie de Châtillon

Marie de Châtillon (1323–1363) was Duchess of Lorraine by her marriage to Duke Rudolph the Valiant. She was the daughter of the Count of Blois and a niece of King Philip VI of France.

When Rudolph was killed at the Battle of Crécy in 1346, their young son John I inherited the duchy, and Marie served as regent until 1354, ruling jointly with the Count of Württemberg. In that year the king dispensed John from his minority, ending the regency.
