The Yarnall Library of Theology is a major American rare book collection affiliated with S. Clement's Church, Philadelphia. It was founded in 1911 under the terms of the wills of Ellis Hornor Yarnall (December 23, 1839 - December 18, 1907) and Emily Yarnall, and subsequently housed at the former Philadelphia Divinity School. The endowed library is now part of the collections of the University of Pennsylvania in Philadelphia.
The library's major areas of focus are theology, patristics, and the liturgy, history and theology of the Anglican Communion and the Episcopal Church in the United States of America. It includes a large number of rare books, incunabula, and illuminated manuscripts, and new material continues to be added.
