The Adams Street Shul, officially the Congregation Agudas Achim Anshei Sfard, is a Modern Orthodox Jewish synagogue located at 168 Adams Street in the village of Nonantum in Newton, Massachusetts, in the United States.

Its Romanesque Revival-style building was listed on the National Register of Historic Places on March 16, 1990.

It was Newton's only synagogue until 1937, when Temple Emanuel was completed on Ward Street.

It was built with significant contribution of labor by the congregation, which included skilled craftsmen.
