Alī ibn Īl-Arslān (Persian: علی بن ایل ارسلان), was a powerful and influential Turkic statesman who served the early Ghaznavid Sultans.
During the reign of Sultan Mahmud, Ali served as the sipahsalar (commander-in-chief) of the Ghaznavid army.
Along with the Ghaznavid vizier Hasanak Mikali, Ali supported Mohammad and expected that he would held absolute power over the Ghaznavid state, while Mohammad would stay as a figurehead.
Mohammad shortly left Ghazni to face his brother who had reached Herat.
When Mohammad arrived to Zamindawar, Ali, in order to officially declare his support to Mas'ud, sent Il-direk to the latter.
