Abū'l-Najm Badr ibn ʿAbdallāh al-Jamālī al-Mustanṣirī, better known as Badr al-Jamali (Arabic: بدر الجمالى‎‎) was a vizier and prominent statesman for the Fatimid Caliphate under Caliph al-Mustansir. His appointment to the vizierate in 1073 restored the fortunes of the Fatimid state, which had faced collapse in the previous decades, but also began a period where the vizierate was dominated by military strongmen who held power through their military strength, rather than through the Caliph's appointment. An Armenian, Badr al-Jamali initiated a wave of Armenian migration into Egypt, and was the first of a series of viziers of Armenian origin, who played a major role in the fortunes of the Fatimid Caliphate over the subsequent century.
