Bilbeis (Coptic Felbs; Arabic بلبيس) is a city in Egypt, in the southeastern part of the Nile Delta, the second largest city in the province of Ash Sharqiya.

History
One of the first cities captured by the Arab army during the Arab conquest of Egypt. According to some reports, the first mosque on the African continent, the Sadat Qureish Mosque, was built in Bilbeis. The city played an important role in the struggle for control of the Fatimid vizirate: first in 1164, when Asad ad-Din Shirkuh, along with his young nephew Salah ad-Din Yusuf, was besieged in the city by the combined forces of Shawar and Amori I of Jerusalem for three months; then in 1168, when the city was attacked by the army of Amori, who took the city three days later, on November 4, and massacred the city. The bloody atrocities gave rise to resentment among the Coptic Egyptians, who saw the crusaders as deliverers, but suffered no less than the Muslim population of Bilbeis. The Copts stopped supporting the crusaders and united with their non-Christian neighbors against the foreigners.

In 1798 the fortifications of the city were rebuilt by order of Napoleon.

Today, the complex of the Egyptian Air Force Academy is located in Bilbeis.
