Kamashi is one of the 20 Districts of Ethiopia, or woredas, in the Benishangul-Gumuz Region of Ethiopia. Part of the Kamashi Zone, it is bordered by the Didessa River on the east which separates it from Yaso and Belo Jegonfoy, by the Oromia Region on the south and west, and by Agalo Mite on the northwest.
This woreda is located on the western slopes of the Didessa River, with elevations ranging from approximately 2000 meters above sea level in the west to just under 1000 meters at the bottom of the Didessa valley. Notable high points in Kamashi include Mount Dade.
The administrative center of this woreda is named Kamashi; population details of this town are not available. Local tradition reports that the first mosque in what is now Benishangul-Gumuz was founded in Kamashi during the early 19th century by a Bidari trader, 'Ummad wad al-Hajj.[1] Ethiopia Call Ministry, an NGO, has announced that they will begin construction of a modern hospital in Kamashi, starting January 2007. Budgeted at 35 million Birr, construction of the hospital is expected to take three years.[2] On 24 July 2009, the Ethiopian Roads Authority announced that it had completed a gravel road 72 kilometers in length between Kamashi and Yaso woredas at a cost of 149 Birr.[3]
