Al-Majidiyyeh Mosque, Ottoman mosque in downtown Beirut, Lebanon

Al-Majidiyyeh Mosque is a mosque in downtown Beirut, Lebanon, converted from a fort in 1844 and named after Sultan Abdul Majid. Its façade gained pointed arches in 1906, and after Civil War damage it was restored by 2004 with a new, taller minaret and an entrance from Khan Antoun Bey Square.

The structure originated as a medieval fortress and was converted into a mosque in 1844 under Sultan Abdul Majid's reign. This transformation reflects a shift from military to religious use during a period of urban change in Beirut.

The mosque serves as a gathering space for the Sunni community in Beirut, where residents participate in daily prayers and observe Islamic holidays together. It remains an active religious center that shapes the spiritual rhythm of the city.

The mosque stands between Khan Antoun Bey and Souk Al-Tawileh, with an entrance reinstated from Khan Antoun Bey Square during the 2000–2004 restoration. The prayer hall is reached by a stone stair from the harbour road side. Visitors should dress modestly and time a visit outside prayer sessions.

During restoration work, graves of the Al-Fakhouri and Al-Itani families, long caretakers of the mosque, were found on its eastern side. Lebanon's mufti Muhammad Rashid Qabbani ruled that the remains be gathered into a few graves on the western side, since most of the buried could no longer be identified after the damage of 1975–1990.
