Abu'l-Abbas Ismail (Persian: ابوالقاسم عباس اسماعیل; died 973 CE), was an Iranian statesman from the Mikalid family, who served the Abbasids, and later the Samanids.
He was the son of Abd-Allah Mikali, a powerful magnate of the Saffarids, and later the governor of Ahvaz under the Abbasids.
When Abu'l-Abbas became old enough, he also began serving the Abbasids and later became the patron of his tutor, the poet Ibn Duraid.
Abu'l-Abbas later moved to Nishapur, in his homeland Khorasan, then under the control of the Iranian Samanids.
In 958, he was appointed as the head of chancery by the vizier of the Samanid ruler Abd al-Malik I, Abu Ja'far 'Utbi.
