The siege of Saint-Dizier took place in the summer of 1544, during the Italian War of 1542–1546, when the Imperial army of Charles V attacked the French city of Saint-Dizier at the beginning of its advance into Champagne. After a two-month siege and the stubborn resistance by a small French garrison, the fortress fell to the Imperial army, personally led by Charles V.
