The Battle of Auberoche was fought during the Gascon campaign of 1345 on 21 October between a 1,200-strong force composed of English and local Gascons under Henry, Earl of Derby, and a French army of 7,000 commanded by Louis of Poitiers. It was fought at the village of Auberoche near Périgueux in northern Aquitaine. At the time, Gascony was a territory of the English Crown. The battle resulted in a heavy French defeat and they suffered very high casualties, with their leaders killed or captured. The battle took place during the early stages of the Hundred Years' War. Along with the Battle of Bergerac earlier in the year, it marked a change in the military balance of power in the region after the French position collapsed. It was one of a series of victories which would lead to Henry of Derby being called "one of the best warriors in the world" by a contemporary chronicler.
