The University of al-Qarawiyyin, also written Al-Karaouine or Al Quaraouiyine, is a university located in Fez, Morocco. It was founded as a mosque by Fatima al-Fihri in 857–859 and subsequently became one of the leading spiritual and educational centers of the Islamic Golden Age. It was incorporated into Morocco's modern state university system in 1963 and officially renamed "University of Al Quaraouiyine" two years later. The mosque building itself is also a significant complex of historical Moroccan and Islamic architecture that features elements from many different periods of Moroccan history.
