Mustahil (Somali: Mustaxiil) is a woreda in the Somali Region of Ethiopia. Part of the Gode Zone, Mustahil is bordered on the south by Somalia, on the west by Kelafo, on the north by the Korahe Zone, and on the east by Ferfer. The Shebelle River is flowing through this woreda. The major town in this woreda is Mustahīl.
The average elevation in this woreda is 310 meters above sea level.[1] As of 2008[update], Mustahil has no all-weather gravel road nor any community roads; about 7.96% of the total population has access to drinking water.[2] Mustahil woreda currently has had good progress and the local government workers have harvested about 50 hectares of Sudan grass so the woreda could help other drought areas.
