Bako Gazer is one of the woredas in the South Ethiopia Regional State.
Part of the Debub Omo Zone, Bako Gazer is bordered on the south by Bena Tsemay, on the west by the Mago River which separates it from Selamago, on the north by the Basketo special woreda and Gelila, on the northeast by the Gamo Gofa Zone, and on the east by Male.
The administrative center of this woreda is Tolta; other town in Bako Gazer include Wub Hamer.
Gelila and Male woredas were separated from Bako Gazer.
Bako Gazar wereda, around the zonal capital of Jinka, is located in the intensively cultivated middle altitudes, and could be said to mark the south-western limits of the traditional Ethiopian highland ox-plough agriculture.
