The Bruttians were an ancient Italic people. They inhabited the southern extremity of Italy, from the frontiers of Lucania to the Sicilian Straits and the promontory of Leucopetra. This roughly corresponds to the modern region of Calabria.

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.
