The Dechatu River is a river of eastern Ethiopia. It rises in the Ahmar Mountains to flow north through the second largest city in the country, Dire Dawa towards the Awash River, entering the city at 9°35′N 41°52′E / 9.583°N 41.867°E. It is unclear if either its flow or river bed eventually reach the Awash. The river appears to lose itself in the Cantur Plain (Buren Meda) north of Dire Dawa.
