The Church of St. Mary is a former Roman Catholic parish church under the authority of the Roman Catholic Archdiocese of New York, located at White Plains Road at 215th Street in Williamsbridge, Bronx, New York City, New York. The church served the Williamsbridge area along with a parish school on East 215th Street, and later in the 1950s was closed and relocated to Carpenter Avenue and East 224th Street to accommodate the growing student population and shift of parishioners. The parish church was closed partly due to the community's changing demographics in the 1990s, reducing the Catholic population to a point where the Archdiocese of New York could no longer support a Catholic parish in the area.
