Historic Congregation B’nai Abraham, officially B’nai Abraham Chabad, is an Orthodox Jewish congregation and synagogue, located at 523-527 Lombard Street, in the Society Hill neighborhood of the Center City of Philadelphia, Pennsylvania, in the United States.

Established as a congregation in 1874 and the current synagogue building completed in 1910, worshipers can access daily, Shabbat, and holy day services in the Ashkenazi rite.

An 1881 almanac identifies the name as Beth Hamedrosh Hagadol B'nai Abraham Anshe Russe.

[3] B'nai Abraham grew in the 1880s with increased immigration of Jews from Russia and Eastern Europe and their settlement in Philadelphia in the city's Jewish quarter.

[7] In 1909, B'nai Abraham retained the services of contractor Samuel Lashner & Co. to construct a new building at a cost of $28,000.

Society Hill's Jewish population contracted in the 1960s and 1970s, and B'nai Abraham identified as a Conservative congregation by 1974.
