Abd al-Aziz ibn al-Walid (Arabic: عبد العزيز بن الوليد; died 728/9) was a member of the Umayyad dynasty and a military leader in the wars against the Byzantine Empire.
He was a son of the Caliph al-Walid I (reigned 705–715). He led in his first campaign against the Byzantines in Asia Minor in 709, when he captured a fortress, although his uncle Maslamah ibn Abd al-Malik led the main raid of the year afterwards. In 710 he led the main Umayyad attack, although under the auspices of Maslamah as commander-in-chief for the Byzantine front, and in 713 he led an attack against the frontier fortress of Gazelon.
In 714/5, his father the Caliph attempted to reverse the succession arrangement, by which the throne would pass to his brother Sulayman, in favour of Abd al-Aziz, but was unable to impose his will. When Sulayman in turn died in 717, Abd al-Aziz intended to claim the throne, but upon learning that Umar II had been chosen as caliph, he presented himself before him and acknowledged his rule. Abd al-Aziz died in Anno Hegirae 110 (728/729 CE).
