Semien Omo (English: North Omo) was a Zone in the Ethiopian Southern Nations, Nationalities, and Peoples' Region (SNNPR). It was named after the Omo River, which flows in the western area of the former zone. In 2000 it was split into three zones: Dawro, Gamo Gofa, and Wolayita; and Basketo and Konta became special woredas.
