The Sultanate of Darfur was a pre-colonial state in present-day Sudan. It existed from 1603 to 24 October 1874, when it fell to the Sudanese warlord Rabih az-Zubayr, and again from 1898 to 1916, when it was occupied by the British and the Egyptians and was integrated into Anglo-Egyptian Sudan. At its peak in the late 18th and early 19th century it stretched all the way from Darfur in the west to Kordofan and the western banks of the White Nile in the east, giving it the size of present-day Nigeria.

Sultan is a position with several historical meanings. Originally, it was an Arabic abstract noun meaning "strength", "authority", "rulership", derived from the verbal noun سلطة sulṭah, meaning "authority" or "power". Later, it came to be used as the title of certain rulers who claimed almost full sovereignty without claiming the overall caliphate, or to refer to a powerful governor of a province within the caliphate. The adjectival form of the word is "sultanic", and the state and territories ruled by a sultan, as well as his office, are referred to as a sultanate.
