Longobucco is a town and comune in the province of Cosenza, in the Calabria region of southern Italy.

Longobucco's name derives from longburg (meaning "far away borough", or "simply long borough"); in the past it was associated with Temesa, or Tempsa, the ancient town Homer was referring to in his Odyssey and famous for its mining fields, from which the Sybarites derived silver to coin their coins, as well as Kroton and the Romans. The first documents about the Argentera date to the 12th century. In 1197 Emperor Henry VI sent to oppido nostro Longoburgi (our town Longburg) his relative Pietro di Livonia to supervise the precious mineral extraction. Even Gioacchino da Fiore went there for the manufacturing of some goblets.
