Koyraboro Senni (or Eastern Songhay, or Koroboro Senni, or Koyra Senni) is a member of the Songhay languages of Mali and is spoken by some 400,000 people along Niger River from Gourma-Rharous, east of Timbuktu, through Bourem, Gao, and Ansongo to the Mali–Niger border.
Although Koyraboro Senni is associated with settled towns, it is a cosmopolitan language which has spread east and west of Gao, to the Fulani or Fula people living at the Mali–Niger border and to the Bozo people of the Niger River. East of Timbuktu, Koyra Senni gives way relatively abruptly to the closely related Koyra Chiini.
