The Abu Haggag Mosque is a mosque in Luxor, Egypt, located within the Ancient Egyptian Luxor Temple. The mosque was built during the reign of the Ayyubid sultan As-Salih Ayyub and was named for the Sufi scholar Yusuf Abu al-Haggag, and it sat within the court of Ramesses II, where part of the temple had been transformed into a Christian basilica in 395 and into a mosque in 640 following the Arab conquest of Egypt. The mosque underwent restoration efforts in 2009 after being exposed to a fire in 2007, and columns and lintels bearing writings from the time of Ramesses II were rediscovered during the renovations. The mosque's annual birthday celebrations for Yusuf Abu el-Haggag include processions of boats parading around the temple, bearing a resemblance to Pharaonic rituals.
