The Lucanians were an Italic tribe living in Lucania, in what is now southern Italy, who spoke an Oscan language, a member of the Italic languages. Today, the inhabitants of the Basilicata region are still called Lucani, and so is their dialect.

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.
