The Mosque of Qaytbay, also known as the Madrasa of Qaytbay, is a historic religious structure in the Qal'at al-Kabsh neighbourhood of Cairo, Egypt. Completed in 1475, it is one of multiple monuments sponsored by the Mamluk sultan al-Ashraf Qaytbay. It is not to be confused with the more famous Funerary complex of Qaytbay in the Northern Cemetery. It is described as both a madrasa and a mosque by scholars, but functions as a mosque today.
