The Presbyterian Historical Society is the oldest continuous denominational historical society in the United States. Its mission is to collect, preserve and share the history of the American Presbyterian and Reformed tradition with the church and broader community. It is a department of the Office of the General Assembly of the Presbyterian Church (U.S.A.).

The Presbyterian Historical Society was organized on May 20, 1852, at the General Assembly meeting of the (Old School) Presbyterian Church in the U.S.A. in Charleston, South Carolina.
