Drexel Development Historic District is a national historic district located in the University City neighborhood of Philadelphia, Pennsylvania. It encompasses 96 contributing rowhouses dated to the mid- to late-19th century. A number of the rowhouses were designed by architect Samuel Sloan. The architectural firm G. W. & W. D. Hewitt designed rowhouses for developer Anthony Joseph Drexel on the block bounded by Pine, new 39th, Baltimore, and 40th Streets. They are representative of a number of popular architectural styles including Second Empire, Italianate, and High Victorian.
It was added to the National Register of Historic Places in 1982.
