The Deir el Qamar Synagogue (Arabic: كنيس دير القمر) is a former Orthodox Jewish congregation and synagogue, located in Deir el Qamar, a village in south-central Lebanon.

[1] The synagogue served the local Jewish population, some of whom were part of the immediate entourage of Fakhr al-Din II.

However, it was eventually sold in 1893, contrary to the counsel of the sages of Jerusalem, who advised against its sale unless for the construction of a new synagogue.

Subsequently, the synagogue was closed to the public for security reasons and was entrusted to the French cultural center by Lebanon's Direction Générale des Antiquités, translated as the General Directorate of Antiquities.
