Saint Clement's Church is an historic Anglo-Catholic parish in Logan Square, Center City, Philadelphia. It is part of the Episcopal Diocese of Pennsylvania. The church, designed by architect John Notman, was built in 1856. It originally incorporated a spire more than 200 feet (61 m) tall; this was found to be too heavy for the foundation and was removed in 1869. In 1929, the church building, which includes the parish house and rectory, and weighs 5,000 short tons (4,500 t), was lifted onto steel rollers and moved 40 feet (12 m) west to allow for the widening of 20th Street. On November 20, 1970, Saint Clement's Church was listed on the National Register of Historic Places.
