Gedeb Asasa is one of the woredas in the Oromia Region of Ethiopia. Part of the Mirab Arsi Zone, Gedeb Asasa is bordered on the south by the Dodola, on the west by Kofele, on the north west by Kore, and on the north and east by Bekoji. The administrative center of the woreda is Asasa.
Ulrich Braukämper theorizes that the name "Gedeb" comes from a Hadiya subgroup mentioned in the Royal Chronicle of Zara Yaqob, where they are referred to as the "Gab". Braukämper has argued that the Hadiya kingdom prior to the Great Oromo migration in the 16th century included in this area, presenting a number of facts supporting his argument, as opposed to other experts who argue that it extended to the east.
The altitude of this woreda ranges from 2200 to 4180 meters above sea level; Mount Kaka is the highest point in the woreda. Melka Wakena Dam, its power station and its lake of 816 hectares are located in this woreda. A survey of the land in this woreda shows that 76.9% is arable or cultivable, 17.3% pasture, 0.4% forest, and the remaining 5.4% is considered swampy, mountainous or otherwise unusable. Garadela and Temela are the two state farms in this woreda. Linseed is an important cash crop.
