Il Kal Grande, also spelled Il Kal Grandi (Judaeo-Spanish: The Great Synagogue), is a former Orthodox Jewish congregation and synagogue, located in Sarajevo, Bosnia and Herzegovina. The congregation worshiped in the Sephardi rite. The building has been used as a cultural center since 1993.

The large synagogue was constructed in the Moorish Revival style in 1930, by a design of the architect Rudolf Lubinski. It was the largest and most ornate synagogue in the Balkans. The building was heavily damaged by the Nazis in 1941 during World War II, and the majority of the Jewish community was murdered in the Holocaust.

After WWII, all the Jews of Sarajevo used the Sarajevo Synagogue, the synagogue of the Ashkenazi community.

The exterior of "Il Kal Grande" was restored in a simplified secular form in 1965, and the former dome was replaced with a flat roof. The building was initially used as the Đuro Đaković Workers' University Center and currently as the Bosnian Cultural Center.
