Mahinbanu Sultan (Persian: مهینبانو سلطان; 1519–1562) was the little daughter of Shah Ismail I of Persia (r. 1524–1576) and Tajlu Khanum.
Mahinbanu Sultan finally died in 1562 at the age of 43 in Qazvin and was buried in her father's tomb in Ardabil according to her will.
Like other family members, she believed in shia beliefs and was a person of repentance, religion and practice of Sharia affairs.
During her pilgrimage to Mashhad, she arranged the golden window and once again took the furniture and lamps with him and inspected all the Sadats and scholars and the atmosphere there.
Despite the fact that Mesopotamia had left Iran and Safavid rule, every year she sent a significant amount of money to the people of Karbala, Najaf, Jabal Amal, Sadat Medina, and the cost of furniture and fittings for the holy shrines.
