Concordville is an unincorporated community in Concord Township, Delaware County, Pennsylvania, United States. It is located 20 miles west-southwest of Philadelphia, at the junction of U.S. Routes 1 and 322. This intersection can be traced back to two of the earliest roads in Pennsylvania, Baltimore Pike which became U.S. 1, and Concord Pike, which connected Pennsylvania with Delaware. The first European settlement in the area occurred about 1700, after Quakers bought land from William Penn.
