The Kingdom of Gomma was one of the kingdoms in the Gibe region of Ethiopia that emerged in the 18th century.

Gomma shared its northern border with Limmu-Ennarea, its western border with Gumma, its southern border with Gera, and its eastern border with Jimma. Its capital was Agaro.

This former kingdom was mostly located in an undulating valley, with a population estimated in 1880 of about 15,000-16,000; its extent is roughly the same as the modern woreda of Gomma. Beckingham and Huntingford considered Gomma, along with Gumma, was the least economically developed of the Gibe kingdoms; however Mohammed Hassen writes that "the people of Gomma devoted themselves to farming, earning a reputation for a high degree of civilization.

Also located in the kingdom of Gomma were two hills, Sinka and Bemba (the last was also called Kella Egdu Biya, or "Gate of the Watching of the Land"), which were sacred to the pagan Oromo. They were inhabited by prophets who lived with large snakes; descendants of these snakes are offered beer and goats' blood by Oromos to allieve their illnesses.
