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 of Tirebolu, Giresun Province, Turkey. It belonged to the Mosynœci and was situated at a distance of 18 km from Cape Zephyrium. (Arrian, Peripl. P. E. p. 17; Anon. Peripl. P. E. p. 13; Plin. vi. 4.) The place is situated on a rocky headland. (Hamilton, Researches, i. p. 257.)
