Zephyrium or Zephyrion (Ancient Greek: Ζεφύριον) was a town of ancient Pontus in the territory of the Mosynoeci, located on a promontory of the same name, 90 stadia to the west of Tripolis, mentioned by several ancient authors.[1]
The promontory is identified as Çam Burnu (formerly Zefre Burnu) in Asiatic Turkey,[2][3] but the town is unlocated.
