Temple Beth Israel (transliterated from Hebrew as "House of Israel"), sometimes called Charter Oak Temple, is an historic former Reform Jewish synagogue and later church building, now cultural center, located at 21 Charter Oak Avenue, in Hartford, Connecticut, in the United States.

The former Temple Beth Israel building is located south of downtown Hartford in the Sheldon-Charter Oak neighborhood.

[2] It is the only known High Victorian eclectic Romanesque work of Keller, who was one of Hartford's leading architects of the second half of the 20th century.

[2] At the time of its listing on the National Register of Historic Places in 1978, the building was owned by the Hartford Redevelopment Agency and despite attempts to put it to other uses, remained unoccupied.

Jewish groups around the state organized to preserve it, and it now houses the Charter Oak Cultural Center.
