Loch Sheldrake Synagogue, also called the Hebrew Congregation of Loch Sheldrake and officially Loch Sheldrake Adas Yisroel, is a historic Orthodox Jewish congregation and synagogue, located on NY 52, north of the junction of NY 52 and Loch Sheldrake Road in Loch Sheldrake, Sullivan County, New York, in the United States. The synagogue was built between 1922 and 1930 of buff-colored brick on a concrete foundation, three bays wide and five bays deep. It is surmounted by a steep gable roof and features a projecting, stepped-gabled entrance pavilion with a limestone parapet. The synagogue was added to the National Register of Historic Places in 1997. The synagogue is open for daily prayer services in the summer and worships according to the Ashkenazi rite. The spiritual leader of the synagogue during the summer is Rabbi Rashi Shapiro.
