The Battle of Tours (10 October 732), also called the Battle of Poitiers and, by Arab sources, the Battle of the Highway of the Martyrs, was an important victory of the Frankish and Burgundian forces under Charles Martel over the raiding parties of the Umayyad Caliphate led by Abdul Rahman Al Ghafiqi, Governor-General of al-Andalus.

The battle was fought in an area between the cities of Poitiers and Tours, in Aquitaine in west-central France, near the village of Moussais-la-Bataille, about 20 kilometres (12 mi) northeast of Poitiers. The location of the battle was close to the border between the Frankish realm and the then-independent Duchy of Aquitaine under Odo the Great.

The Franks were victorious. Abdul Rahman Al Ghafiqi was killed, and Charles subsequently extended his authority in the south. Details of the battle, including its exact location and the number of combatants, cannot be determined from the accounts that have survived. Notably, the Frankish troops won the battle without cavalry.

The battle helped lay the foundations of the Carolingian Empire and Frankish domination of western Europe for the next century. Most historians agree that "the establishment of Frankish power in western Europe shaped that continent's destiny and the Battle of Tours confirmed that power."
