Anshei Glen Wild Synagogue is a small Orthodox synagogue built in the 1920s for a congregation established the previous decade. It is located on Glen Wild Road, Sullivan County Route 58, in the unincorporated community of Glen Wild, New York, United States. It was founded by a local family and has never had its own rabbi. The synagogue is preserved virtually intact from the time of its construction and was listed on the National Register of Historic Places in 1999.
