Aisan Daulat Begum (? – June, 1505, other names Ishan Daulat, Isan Daulat, Ësan Dawlat) was the Queen consort of Moghulistan as the first wife and chief consort of Yunus Khan, a descendant of Chaghatai Khan, the second son of Genghis Khan. She was the mother of Qutlugh Nigar Khanum, and hence the grandmother of the first Mughal emperor, Babur.

Aisan Daulat Begum was the daughter of the Sagharichi Tuman Begs, a subdivision of the Kunchi Mughals. Her father was a powerful tribal chief, Mir Sher Ali Haji Kunji (Qunchin) Beg. She had many brothers, of whom three, Shiram Beg, Mazid Beg, and Ali Dost Beg, took leading parts in Babur's affairs.

In 1456 Abu Sa'id Mirza, who had become the ruler of Transoxiana, sent for Yunus Khan. Abu Sa'id had become annoyed with the frequent raids that the Moghuls under Esen Buqa made into his territory. He raised Yunus to the khanship and sent him with an army to Moghulistan to oppose his brother. Yunus Khan quickly gained the support of several amirs and married Aisan Daulat Begum. Aisan Daulat Begum played an important part in contemporary politics right from her young days, when she was to be married. The Baburnama says that by marrying Aisan Daulat Begum, Yunus Khan along with Aisan Daulat were seated on a white felt. According to the Tureh or ancient Institutions of the Mughals, he was ordered and raised to khanship by the Sagharichi Tuman Begs who had attacked Moghulistan.

Born in the desert and herself used to the rigors of the wild country, Aisan Daulat Begum was certainly the one to inculcate tenacity, self-reliance, courage to face hardships and a die hard attitude in her grandson Babur, which together became the integral feature of Babur's character and later the key to his success. Aisan Daulat Begum shared the many hardships for her husband's life for thirty years. Several times she fell into the hands of the enemy, but always came back from their clutches safely.
