The Mosque of Amir Qijmas al-Ishaqi (Arabic: مسجد قجماس الإسحاقي‎) or Abu Hurayba Mosque (Arabic: مسجد أبو حريبة‎) (sometimes written Abu Heriba) is a late Mamluk-era mosque in Cairo, Egypt. It dates from 1480-81 CE and is located in the historic al-Darb al-Ahmar district, near Bab Zuweila. It is considered by many to be one of the finest examples of late Mamluk architecture.
