The Assaf dynasty (also called Banu Assaf) were a Sunni Muslim and ethnic Turkmen dynasty of chieftains based in the Keserwan region of Mount Lebanon in the 14th–16th centuries. They came to the area in 1306 after being assigned by the Bahri Mamluks to guard the coastal region between Beirut and Byblos and to check the power of the mostly Shia Muslim population at the time. During this period, they established their headquarters in Ghazir, which served as the Assafs' base throughout their rule.
