Abu'l Ghazi Sultan Alqas Mirza (Persian: ابوالقاسم غازی سلطان القاس میرزا), better known as Alqas Mirza (القاس میرزا; 15 March 1516 – 9 April 1550), was a Safavid prince and the second surviving son of king (shah) Ismail I (r. 1501–1524). In early 1546, with Ottoman help, he staged a revolt against his brother Tahmasp I (r. 1524–1576), who was king at the time.
