Mamıq or (Mamuq) (?-1498/1499), was possibly the same person who was Khan of Siberia Khanate. After murdering Ibak Khan in 1495, Mamuq left Tyumen Ulus and shifted his capital to Qashliq better known as Sibir. He led faithful Tyumen troops and Nogais to invade Kazan in 1495/96.
With the support of coup of Qarachi Qol Muhammad he occupied Kazan in 1495 becoming Khan of Kazan (1495–1496). He struggled against local nobility, trying to centralize power. But finding the people and nobility of Kazan resistant and possible arrival of Russian reinforcements he left the place and died on his way home in 1497/98.
