The Khanate of Sibir, also historically called the Khanate of Turan,is a Uralo-Siberian Tatar Khanate located in southwestern Siberia.

Throughout its history, members of the Shaybanid and Taibugid dynasties often contest the rule over the Khanate; each of these competing tribes represent direct patrilineal descendants of Genghis Khan through his eldest son Jochi and his fifth son Shayban (Shiban).

The Sibir Khanate itself originally forms an integral part of the Mongol Empire, and later of the White Horde and the Golden Horde.The Sibir Khanate has an ethnically diverse population of Khanty, Mansi, Nenets, Selkup and Siberian Tatar people.

The Sibir Khanate is the northernmost Muslim state in recorded history.Defeat of the Khanate by the forces of Yermak Timofeyevich in 1582 marks the beginning of the Russian conquest of Siberia.
