The Battle of Corinth of 146 BC, also known as the Battle of Leucapetra or the Battle of Lefkopetra, was a decisive engagement fought between the Roman Republic and the Greek city-state of Corinth and its allies in the Achaean League. The battle marked the end of the Achaean War and the beginning of the period of Roman domination in Greek history, and is also notable for the complete and total destruction of Corinth by the Romans in its aftermath.

Ancient Greece was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity, that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period.
