Sherka is one of the woredas in the Oromia Region of Ethiopia. Research by Ulrich Braukämper uncovered a local tradition that traced the origins of this woreda's name to an ancient Ethiopian province, Sharkha, which vanished as a political unit in the 16th century. Part of the Arsi Zone, Sherka is bordered on the south by the Shebelle River which separates it from the Bale Zone, on the southwest by Bekoji, on the west by Digeluna Tijo, on the north by Tena, and on the east by Robe.
