Menjiwo is one of the woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. The name Menjiwo is derived from the province Manjo of the Kingdom of Kaffa; however, the province of Manjo lay within the boundaries of neighboring Ginbo, while Menjiwo occupies the lands of the Gallo province of the former kingdom. Part of the Keffa Zone, Menjiwo is bordered on the south by Telo, on the southwest by Decha, on the west by Ginbo, on the north by the Gojeb River which separates it from the Oromia Region, and on the east by the Konta special woreda. The major town in Menjiwo is Adiya Kaka.
This woreda has been described as "one of the most isolated zones in the Region, with most kebeles inaccessible by road throughout the year." According to a 2004 report, Menjiwo had 56 kilometers of dry-weather roads, for an average road density of 53 kilometers per 1000 square kilometers. Despite the lack of all-weather roads, this woreda possesses "a largely self-contained economy, not wealthy, but economically secure. Major cash crops include corn, teff, wheat, and haricot beans. Other important sources of income include selling butter.
