The Iapygians (Greek: Ἰάπυγες, Ĭāpyges; Latin: Iapyges, Iapygii) were an Indo-European people who inhabited Apulia in classical antiquity. They lived in the eponymous region Iapygia and were divided in three populations: the Daunians, Peucetians and Messapians. Their land was annexed by the Roman Republic, and they were eventually Latinized and assimilated into Roman culture.
