Tripolis (Greek: Τρίπολις), formerly Ischopolis, was an ancient fortress city in Pontus Polemoniacus, on a river of the same name, and with a tolerably good harbor; it is now the site and namesake of the city of Tirebolu in Giresun Province, Turkey. It belonged to the Mossynoeci and was situated at a distance of 18 km east from Cape Zephyrium. (Arrian, Periplus Ponti Euxini 16.4; Anon. Periplus Ponti Euxini p. 13; Pliny the Elder, Naturalis Historia vi.4.11) The place is situated on a rocky headland. (Hamilton, Researches, i. p. 257.)
