Loma Bosa (also known as simply Loma) was one of the 77 woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Dawro Zone, Loma Bosa was bordered on the south by the Gamo Gofa Zone, on the west by Isara Tocha, on the northwest by Mareka Gena, on the north by the Kembata Tembaro Zone, and on the east by the Wolayita Zone; the Omo River defined Loma Bose's boundary on the northeast, east and south.
