Nisan Bak was a leader of the Hasidic Jewish community of the Old Yishuv in Ottoman Palestine. He was the founder of two Jewish neighborhoods in Jerusalem, Kirya Ne'emana and a Yemenite Jewish neighborhood, and builder of the Tiferet Yisrael Synagogue, also known as the Nisan Bak Shul.

Kirya Ne'emana, commonly known as Batei Nissan Bak was a historical Hasidic Jewish neighborhood established opposite Damascus Gate in the New City of Jerusalem in 1875. In the 1880s and 1890s it was joined by additional housing for Syrian, Iraqi, Persian, Georgian, and Caucasian Jews. Most of the residents fled the area during the 1929 Palestine riots and their houses were occupied by Christians and Muslims. In the 2000s a handful of Jewish families reclaimed houses in the neighborhood.
