Debub Omo (or "South Omo") is a Zone in the Ethiopian Southern Nations, Nationalities and Peoples Region (SNNPR). Debub Omo is bordered on the south by Kenya, on the southwest by the Ilemi Triangle, on the west by Bench Maji, on the northwest by Keficho Shekicho, on the north by Semien Omo, on the northeast by the Dirashe and Konso Special Woredas, and on the east by the Oromia Region. The administrative center of Debub Omo is Jinka.
This zone is named for the Omo River, a river that flows south into Lake Turkana on the western side. Notable high points include Mount Smith (2560 meters) and Mount Mago (2538 meters). West of the Omo is the most sparsely populated part of Ethiopia, inhabited by nomadic and semi-nomadic ethnic groups. A 1996 report described the infrastructure of the Zone as "weak and for the most part non-existent; this is a disadvantage inherited from historical neglect of a typical marginal region." It also observed that the Debub Omo Zone "one of Ethiopian's socially most diverse zones. It contains a minimum of 12 different ethnic groups, and possibly as many as 21. Social diversity therefore compounds the existing problems of isolation, acute shortage of basic infrastructure as well as scarcity of professional and technical man-power."
Debub Omo has 462 kilometers of all-weather roads and 412 kilometers of dry-weather roads, for an average road density of 37 kilometers per 1000 square kilometers. According to the Central Statistical Agency (CSA) 1,364 tons of coffee were produced in Debub Omo in the year ending in 2005, representing 1.36% of the SNNPR's output and 0.6% of Ethiopia's total output.
Based on the 2007 Census conducted by the CSA, this Zone has a total population of 573,435, of whom 286,607 are men and 286,828 women; with an area of 21,055.92 square kilometers, Debub Omo has a population density of 27.23. While 43,203 or 7.53% are urban inhabitants, a further 25,518 or 4.45% are pastoralists. A total of 125,388 households were counted in this Zone, which results in an average of 4.57 persons to a household, and 121,309 housing units.
In the 1994 Census, Debub Omo had a population of 327,867 in 77,694 households, of whom 165,064 were men and 162,803 women; 22,084 or 6.74% of its population were urban dwellers. The six largest ethnic groups reported in this Zone were the Aari (42.94%), the Male (13.49%), the Hamer (12.89%), the Daasanach (9.77%), the Amhara (5.59%), and the Nyangatom (4.33%); all other ethnic groups made up 10.99% of the population.

The memorandum gave this zone a drought risk rating of 348.
This Zone was selected by the Ministry of Agriculture and Rural Development in 2004 as one of several areas for voluntary resettlement for farmers from overpopulated areas; no specific of the Zones woredas were identified in this program. Debub Omo became the new home for a total of 4748 heads of households and 18,992 total family members.
