The Afrin River is a tributary of the Orontes River in Turkey and Syria. It rises in the Kartal Mountains in Gaziantep Province of Turkey, flows south through the city of Afrin in northwest Syria, then reenters Turkey. It joins the Karasu at the site of the former Lake Amik, and its waters flow to the Orontes by a canal.
The total length of the river is 131 kilometres, of which 54 kilometres is in Syria. The source of around a quarter of the river water is in Syria. More precisely, about 250 million m3 of the annual flow of the river comes from the Hatay Province of Turkey, while about 60 million m3 originates in Syria. The river is impounded by Syrias Afrin Dam to the north of the city of Afrin.
