Sayf ad-Din Sirghitmish ibn Abdullah an-Nasiri, better known as Sirghitmish (also spelled Sarghitmish) (died 1358) was a prominent Mamluk emir during the reign of Sultan an-Nasir Hasan. By 1357, Sirgitmish was the most powerful emir in an-Nasir Hasan’s court. That year, he had the Madrasa of Sirghitmish built in Cairo. In 1358, the sultan’s suspicions of a coup plot by Sirghitmish led to his imprisonment and subsequent death.
