Picenum was a region of ancient Italy. The name is an exonym assigned by the Romans, who conquered and incorporated it into the Roman Republic. Picenum was the Regio V in the augustan territorial organization of Roman Italy. Picenum was also the birthplace of such Roman notables as Pompey the Great and his father Pompeius Strabo. It was situated in what is now Marche and the northern part of Abruzzo. The Piceni or Picentes were the native population of Picenum, but they were not of uniform ethnicity. They maintained a religious centre in Cupra Marittima, in honor of the goddess Cupra.
