Congregation B'nai Abraham, Orthodox synagogue in Society Hill, Philadelphia, United States

Congregation B'nai Abraham is an Orthodox synagogue at 523-527 Lombard Street in Philadelphia's Society Hill. Its 1910 building, designed by Charles W. Bolton & Co. in Byzantine Revival style, was inspired by Manhattan's Pike Street Synagogue. The facade features a central dome and arched windows.

Founded in 1874 as the Russian shul by immigrants from Russia and Eastern Europe, the congregation bought the former Wesley Church building at 521 Lombard Street for $6,500 in 1885. Contractor Samuel Lashner & Co. built the present synagogue in 1909–1910 for $28,000, designed by architect Charles W. Bolton & Co. in Byzantine Revival style, inspired by Manhattan's Pike Street Synagogue. A lightning strike in July 1926 started a fire causing $75,000 in damage; all 23 Torah scrolls were rescued.

The congregation worships in the Ashkenazi rite, with daily, Shabbat and holy day services. Its name, B'nai Abraham, means Sons of Abraham, and the original 1882 charter called the group Chevra B'nai Avrohom Mi Russe, the Organization Sons of Abraham from Russia. The building also houses a Jewish preschool and Lubavitch of Center City.
