The battle of Bitola (Bulgarian: Битка при Битоля) took place near the town of Bitola, in Bulgarian territory, between a Bulgarian army under the command of the voivode Ivats and a Byzantine army led by the strategos George Gonitsiates. It was one of the last open battles between the First Bulgarian Empire and the Byzantine Empire. The Bulgarians were victorious and the Byzantine Emperor Basil II had to retreat from the Bulgarian capital Ohrid, whose outer walls were by that time already breached by the Bulgarians. However, the Bulgarian victory only postponed the fall of Bulgaria to Byzantine rule in 1018.
