The Hadiya Sultanate (r. 13th century-15th century) was an ancient kingdom located in southwestern Ethiopia, south of the Abbay River and west of Shewa. It was ruled by the Hadiya people, who spoke the Cushitic Hadiyya language. The historical Hadiya area was situated between Kambaat, Gamo and Waj, southwest of Shewa. By 1850, Hadiya is placed north-west of lakes Zway and Langano but still between these areas.
