Abūʾl-Maymūn ʿAbd al-Majīd ibn Muḥammad ibn al-Mustanṣir, better known by his regnal name as al-Ḥāfiẓ li-Dīn Allāh (Arabic: الحافظ لدين الله, lit. 'Keeper of God's Religion'), was the eleventh Fatimid caliph, ruling over Egypt from 1132 to his death in 1149, and the 21st imam of Hafizi Isma'ilism.

Al-Hafiz first rose to power as regent after the death of his cousin, al-Amir bi-Ahkam Allah, in October 1130. Al-Amir had only left an infant son, al-Tayyib, as a possible successor, so al-Hafiz—as the oldest surviving member of the dynasty—became regent. Al-Tayyib was apparently sidelined and possibly killed by the new regime, which was in turn overthrown within a few days by the army under Kutayfat. The latter imprisoned al-Hafiz, and moved to depose the Fatimids and replace Isma'ilism with a personal regime, possibly based on Twelver Shi'ism, with himself as the Hidden Imam's all-powerful vicegerent. Kutayfat's regime was toppled when he was murdered by Fatimid loyalists in December 1131, and al-Hafiz was freed and restored as regent.

On 23 January 1132, al-Hafiz proclaimed himself as the legitimate Isma'ili imam and caliph. While necessary in view of the lack of another heir, the succession was highly irregular, as the Isma'ili imamate had previously only been passed from father to son, by explicit designation (naṣṣ). Al-Hafiz was largely accepted in the Fatimid-ruled territories, but many Isma'ili followers abroad refused to recognize him and regarded the vanished al-Tayyib as their imam, causing the Hafizi–Tayyibi schism in Musta'li Isma'ilism. Even in Egypt, his legitimacy was repeatedly challenged, and his reign was troubled by constant uprisings and power struggles. In an effort to bolster his legitimacy, al-Hafiz was particularly active in the construction and restoration of shrines dedicated to members of the wider Alid family. Al-Hafiz's reign was mostly quiet on the external front. Despite continuing hostilities with the Kingdom of Jerusalem around Ascalon, both powers were preoccupied elsewhere for the most part. The Fatimid court also maintained contact with the Burids in Syria and King Roger II of Sicily, who at this time began his expansion into the former Fatimid domains of Ifriqiya, and adopted many of the practices of the Fatimid court for his own administration.

As ruler, al-Hafiz tried to rein in his over-mighty viziers, with mixed success. He was repeatedly forced to give way to the demands of various military factions, and was ultimately unable to halt the evolution of the vizierate into a de facto sultanate independent of the caliph. Thus al-Hafiz's own son Hasan forced him to name him vizier in 1134, ousting another of the Caliph's sons from the post. Hasan's reign proved tyrannical and he was overthrown by the army in March 1135. The appointment of the Christian Bahram al-Armani to the vizierate after that caused a severe reaction among the Muslim population due to Bahram's pro-Christian policies. This led to another uprising and the appointment of the Sunni Ridwan ibn Walakhshi to the vizierate in 1137. Ridwan not only instituted anti-Christian and anti-Jewish measures, but aimed to overthrow al-Hafiz and replace the Fatimid dynasty with a Sunni regime headed by himself. With the support of the Cairo populace, al-Hafiz thwarted his ambitions and ousted Ridwan in 1139. For the next ten years, the Caliph ruled without a vizier, instead entrusting the administration to a succession of secretaries, with Ibn Masal as leading minister. This period was plagued by uprisings and natural disasters, but al-Hafiz persevered until his death in October 1149. His successors would be reduced to puppets at the hands of powerful viziers, until the end of the Fatimid Caliphate in 1171.
