Bale, also known as Bali, was a historical Muslim region located in the southeastern part of modern Ethiopia. It bordered the Dawaro to the north, Hadiya in the west, and Adal in the east and its core areas were located around the Shebelle River. However, the borders of Bale during the medieval period are unclear - it is usually placed around the Wabe Shebelle river, another river that shaped its borders was the Wabe River. Overall, borders of historical Bale corresponded to the modern districts of Goba, Sinana-Dinsho, Agarfa, Gasera and Goro. In the 14th century it was located between Ifat and Solomonic tributary state of Hadiya.

Ulrich Braukämper, after discussing the evidence, states that this former dependency "occupied an area in the northeast of the province which later was named after it, between the mountain range of Urgoma and the eastern Wabi Bend."
