The Al Fassiyine Synagogue or Slat Al Fassiyine (Hebrew: בית הכנסת סלאת אל פאסיין; Arabic: بيعة صلاة الفاسيين) is a synagogue located in the Mellah of Fes el-Jdid, within the historic medina of Fez, Morocco.

[3] In 1791–92, Moulay Yazid expelled the Jews from the Mellah and turned Slat al Fassiyine into a prison.

The synagogue continued being used actively through the end of the 1950s,[4] when most of the Jewish community left the country for Israel, France, and Montreal (Canada).

After Morocco gained its independence from France in 1956, the synagogue fell into disrepair and was eventually turned into a carpet-making workshop, and later a boxing gymnasium.

[5][6] The synagogue was reinaugurated in February 2013 by the Prime Minister Abdelilah Benkirane,[7][8] with the funds for the restoration coming from the German government, the Jewish community of Fez, the Foundation for Moroccan Jewish Cultural Heritage,[9] and the Moroccan government.
