Belbeis is an ancient fortress city on the eastern edge of the southern Nile delta in Egypt, the site of the Ancient city and former bishopric of Phelbes and a Latin Catholic titular see.
The city is small in size but densely populated, with over 407,300 residents. It also houses the Egyptian Air Force Academy complex, which contains the town's largest public school in Al-Zafer.
The mosque of Sadat Qureish, which is the oldest mosque in Egypt, and perhaps the entirety of Africa, is located in Belbeis.
