The Battle of Asculum was a battle that took place near Asculum in 279 BC, and was thought to have lasted either one or two days, between the Roman Republic under the command of the consuls Publius Decius Mus and Publius Sulpicius Saverrio, and the forces of King Pyrrhus of Epirus. The battle took place during the Pyrrhic War, after the Battle of Heraclea of 280 BC, which was the first battle of the war. There currently exist accounts of this battle only by three ancient historians: Dionysius of Halicarnassus, Plutarch, and Cassius Dio, although these historians in turn reference other historians whose work is now lost. Asculum was in Lucanian territory, in southern Italy.
