Abu Ishaq Ibrahim, also known as Ishaq ibn Alp-Tegin, was a Turkic officer, who was the Samanid governor of Ghazna from September 963 to November 966. He was the son and successor of Alp-Tegin.

Abu Ishaq Ibrahim briefly lost control of Ghazna after an invasion by its former ruler, Abu Bakr Lawik. However, he managed to regain it with Samanid aid. Some time later, Abu Ishaq Ibrahim died and was succeeded by a Turkic slave commander named Bilgetegin.
