St. Philip's Episcopal Church is an historic Episcopal church located at 129 West Mound Street in Circleville, Ohio. The first Episcopal service in Circleville was held on May 26, 1817, by the Rev. Philander Chase, who in 1819 became the first bishop of the Episcopal Diocese of Ohio. The stone church building was built in 1866 in a mixed Gothic and Tudor Revival style and was consecrated in 1868. Besides its actual name, the church has been known as the "Little Church on the Mound," because it sits on the base of what was formerly one of Circleville's numerous Native American mounds that was historically known as "Mount Gilboa."
