The Deccan sultanates were five late-medieval Indian kingdoms—on the Deccan Plateau between the Krishna River and the Vindhya Range—that were created from the disintegration of the Bahamani Sultanate and ruled by Muslim dynasties: namely Ahmadnagar, Berar, Bidar, Bijapur, and Golconda. The sultanates had become independent during the break-up of the Bahmani Sultanate. The five sultanates owed their existence to the declaration of independence of Ahmadnagar in 1490, followed by Bijapur and Berar in the same year. Golconda became independent in 1518, and Bidar in 1528.

The large Deccan Plateau in southern India is located between the Western Ghats and the Eastern Ghats, and is loosely defined as the peninsular region between these ranges that is south of the Narmada River. To the north, it is bounded by the Satpura and Vindhya Ranges.
