Shah Begum (died 1508) was the Queen consort of Moghulistan as the second wife of Yunus Khan, a descendant of Chaghatai Khan, the second son of Genghis Khan. She was the mother of Mahmud Khan and Ahmad Alaq, the next Moghul Khans of Moghulistan.

Shah Begum was the fourth daughter of Shah Sultan Muhammad, king of Badakhshan. Her father's family boasted of their descent from Alexander the Great. She contended that they had swayed the scepter of Badakhshan from three thousand years.

She had five sisters, one of them was married to Sultan Masud Kabuli, who was a descendant of Amir Timur. Aother sister of hers, Sultanum Begum was married to Sultan Abu Sa'id Mirza, and bore him Abubakr Mirza. The Mirza, after the death of his father, engaged in war with Sultan Husain Mirza, and caused much disturbance in the kingdom. Her third sister was married to Ibrahim Barlas, who bore him a son, Jihangir Barlas, who at the end of Chaghatai rule became chief minister. Her fourth sister was married to Sayyid Shah Buzurg Arhangi. Her fifth sister was married to Shaikh Abdullah Barlas, who bore him three sons, Sultan Vais Barlas, Mizrab Barlas and Sultan Sanjar.

When Sultan Yunus Khan returned a second time from Khorasan, Amir Sayyid Ali had died, and Saniz Mirza had sought the assistance of Yunus Khan. Yunus Khan in those days, often went backwards and forwards to Kashghar. At that time, the Khan sent Amir Zia-ud-Din, who was one of the most eminent Sayyids of Kashghar, to Sultan Muhammad, in Badakhshan, to ask one of his most immaculate daughters in marriage. Sayyid Zia-ud-Din brought Shah Begum back with him to Kashghar, and delivered her over to the Khan. Shah Begum married Yunis Khan as his second wife in 1461.

By her Yunis Khan had two sons, the elder was Sultan Mahmud. In Samarkand he was generally called Janikeh Khan. The younger khan was Sultan Ahmad Khan, and was well known by the name of Ilcheh Khan. She also had two daughters. The elder daughter was Sultan Nigar Khanum, who had married Sultan Mahmud Mirza, successively Sultan of Hissar and of Samarkand, by whom she had an only son, Sultan Weis, or, he was generally called, Khan Mirza; she married afterwards two khans of the Kaizak Uzbeks in succession. Shah Begum's younger daughter, Daulat Sultan Khanum married Taimur Sultan, the son of Sheibani Khan.
