The Rioni (Georgian: რიონი, Rioni; Ancient Greek: Φᾶσις, Phᾶsis) is the main river of western Georgia. It originates in the Caucasus Mountains, in the region of Racha and flows west to the Black Sea, entering it north of the city of Poti (near ancient Phasis). The city of Kutaisi, once the ancient city of Colchis, lies on its banks. It drains the western Transcaucasus into the Black Sea while the river Kura, drains the eastern Transcaucasus into the Caspian Sea.
