Lucania was a historical region of Southern Italy, corresponding to the modern-day region of Basilicata. It was the land of the Lucani, an Oscan people. It extended from the Tyrrhenian Sea to the Gulf of Taranto. It bordered with Samnium and Campania in the north, Apulia in the east, and Bruttium in the south-west, and was at the tip of the peninsula which is now called Calabria. It comprised almost all the modern region of Basilicata, the southern part of the Province of Salerno and a northern portion of the Province of Cosenza.

Basilicata, also known by its ancient name Lucania, is an administrative region in Southern Italy, bordering on Campania to the west, Apulia to the north and east, and Calabria to the south. It has two coastlines: a 30-km stretch on the Tyrrhenian Sea between Campania and Calabria, and a longer coastline along the Gulf of Taranto between Calabria and Apulia. The region can be thought of as the "instep" of the "boot" of Italy, with Calabria functioning as the "toe" and Apulia the "heel".
