The Kingdom of Gumma was one of the kingdoms in the Gibe region of Ethiopia that emerged in the 18th century. Its eastern border was formed by the bend of the Didessa River, which separated it from (proceeding downstream to upstream) Limmu-Ennarea to the northeast, and the kingdoms of Gomma and Gera to the south. Beyond its northern border were various Macha Oromo groups, and to the west Sidamo groups. Its territory corresponds approximately with the modern woredas of Gechi and Didessa.
