The Peucetians (Greek: Πευκέτιοι Peukétioi; Latin: Peucetii) were an Iapygian tribe which inhabited western and central Apulia in classical antiquity. Besides this original Greek name, they were also called the Poidikloi (Greek: Ποίδικλοι) by the later Greek writer Strabo and Poediculi by Latin writers. Together with the Daunians and the Messapians they constituted the Iapygians. They shared the Messapian language with these two other tribes, but had developed a separate archaeological culture by the seventh century BC. They occupied a region called Peucetia, which is now called the Terra di Bari. It was bordered by the Ofanto river and the Murge in the north, the Bradano river in the west and the territories of the Greek colony of Taras and the Messapians in the south. This region is mostly coincident with the Metropolitan City of Bari and a part of the Province of Taranto today.
They had three important towns: Canosa, Silvium and Bitonto; the present capital of Apulia, Bari, had not much importance.
