The Battle of Mello was the decisive and largest engagement of the Peasant Jacquerie of 1358, a rebellion of peasants in the Beauvais region of France, a major upheaval in this region at the height of the Hundred Years' War with England. The battle was fought at almost the same time as another major battle fought at Meaux, where the Jacquerie rebels (or Jacques Bonhommes) joined the Parisian militia in assaulting a royal stronghold.
