Barbarikon (Βαρβαρικόν) was the name of a sea port near the modern-day city of Karachi, Sindh, Pakistan, important in the Hellenistic era in Indian Ocean trade. It is also a Greek version of the term Barbaricum, designating areas outside civilization and/or the Roman Empire. Barbarikon is mentioned briefly in the Periplus of the Erythraean Sea: Its principal function beyond supplying its immediate hinterland was as a transshipment port for supplies of Persian turquoise and Afghan lapis lazuli, to be carried overland to Egypt.
