Awash is a market town in central Ethiopia. Located in Administrative Zone 3 of the Afar Region, above a gorge on the Awash River, after which the town is named, the town lies on the Addis Ababa - Djibouti Railway, which crosses the gorge by a bridge there.
Awash lies outside the Awash National Park, which is known for its wildlife, for the Mount Fentale caldera and for the Filwoha Hot Springs. Its market is held on Mondays, where Afar and Kereyu crafts can be found.
Based on figures from the Central Statistical Agency in 2005, Awash has an estimated total population of 11,053, of whom 5,748 were males and 5,305 were females. According to the 1994 national census, the town had a population of 8,684. It is the largest settlement in Awash Fentale woreda.
Awash grew up around the railroad station, which was opened not long about 1917 when the railway had reached this far into Ethiopia. A hotel for passengers was built in Awash about that time. The fourth post office in Ethiopia (after Harar, Dire Dawa and Addis Ababa) was established in Awash on 1 September 1923, but it may not have been much of a point of origin and arrival but rather a place on the line between the capital and the coast.
During the Italian occupation, Awash still provided a post office, a telegraph station, the hotel, and restaurant. The town was occupied in April 1941 by the 22nd East African Brigade of the King's African Rifles, who had advanced for three days from Dire Dawa. Elements of this brigade afterwards continued their advance across the Awash at this point on 3 April 1941, although the road and rail bridge had been demolished by the retreating Italians. By 1953, the bridge had been rebuilt.
One of the five camps to train conscripts of the People's Militia (reconstituted in the spring of 1977 as the "Red Army") was located at Awash. On 14 January 1985 a train derailed and plunged four carriages into a ravine; the crash was estimated to have killed 400 people and injured another 500.
