The Mad War (French: la Guerre folle) was a late medieval conflict between a coalition of feudal lords and the French monarchy. It occurred during the regency of Anne of Beaujeu in the period after the death of Louis XI and before the majority of Charles VIII. The war began in 1485 and ended in 1488.

The principal lords involved were Louis II of Orléans, the cousin of the King (and future Louis XII of France); Francis II of Brittany; René II, Duke of Lorraine; Alain d'Albret; Jean de Châlon, Prince of Orange; and Charles, Count of Angoulême. Other leading lords supported the revolt, including Philippe de Commines and Odet d'Aydie, Count of Commines and Governor of Guyenne.

As a revolt against French royal authority, it was supported by the foreign enemies of the King of France: England, Spain, and Austria. Its principal outcome was the absorption of Brittany into the French kingdom.
