Gamo Gofa is a Zone in the Ethiopian Southern Nations, Nationalities, and Peoples' Region (SNNPR). It is named for the Gamo and Gofa peoples, whose homelands lie in this Zone. Gamo Gofa is bordered on the south by the Dirashe special woreda, on the southwest by Debub (South) Omo and the Basketo special woreda, on the northwest by Konta special woreda, on the north by Dawro and Wolayita, on the northeast by the Lake Abaya which separates it from the Oromia Region, and on the southeast by the Amaro special woreda. The administrative center of Gamo Gofa is Arba Minch.
Gamo Gofa has 431 kilometers of all-weather roads and 122 kilometers of dry-weather roads, for an average road density of 45 kilometers per 1000 square kilometers. The highest point in this Zone is Mount Gughe (4,207 meters above sea level). The Lake Chamo is located at the southeastern part of Gamo Gofa just south of Lake Abaya. The Nechisar National Park is located between these two lakes.
Originally Gamo Gofa was part of the Semien (North) Omo Zone, and the 1994 national census counted its inhabitants as part of that Zone. However friction between the various ethnic groups in Semien Omo, which was often blamed on the Welayta for "ethnic chauvinism" and despite the efforts of the ruling party to emphasize the need to co-ordinate, consolidate, and unify the smaller ethnic units to achieve the "efficient use of scarce government resources", eventually led to the division of the Zone in 2000, resulting with the creation of not only the Gamo Gofa, but also the Dawro and Wolayita Zones and two special woredas.
