Khal Adath Jeshurun, officially K'hal Adath Jeshurun,[1] abbreviated as KAJ, is an Orthodox Jewish congregation and synagogue located at 85-93 Bennett Avenue in the Washington Heights neighborhood of Manhattan in New York City, New York, United States.

Khal Adath Jeshurun bases its approach, and structure, on Hirsch's philosophy of Torah im Derech Eretz; it was re-established according to the protocol originally drawn in 1850, to which the congregation continues to adhere.

K'hal Adath Jeshurun was founded in 1939 in Washington Heights by refugees from Germany, following Kristallnacht.

[3] The current synagogue building was completed in 1952, renovating initial premises at 90 Bennett Avenue.

True to the "full-service community" as originally established in Frankfurt, the community includes a synagogue, an elementary school (located at 85 Bennett Avenue), various educational facilities, a social hall, a high school, a Beth Midrash (these are several blocks north, where Bennett Avenue meets 190th or 191st St).
