Congregation Chasam Sopher is an Orthodox Jewish synagogue located at 10 Clinton Street on the Lower East Side of Manhattan, in New York City, New York, United States.

History

The congregation was formed in 1892 by the merger of two congregations of immigrants from Poland. It occupies a historic Romanesque Revival synagogue building built in 1853 by Congregation Rodeph Sholom. The synagogue building is among the oldest synagogues still standing in the United States, the second-oldest synagogue building in New York, and the oldest still in use in the state.

Renovation of the upstairs, completed in 2006, included conservation of the Torah ark, the installation of new stained-glass windows, and stripping the interior of paint to expose the original wood. The outside was also landscaped, creating a garden for the neighborhood.

As of 2011, the rabbi was Azriel Siff.
