This is a list of public artworks in Philadelphia. The Association for Public Art estimates the city has thousands of public artworks; the Smithsonian lists more than 700. Since 1959 nearly 400 works of public art have been created as part of the city's Percent for Art program, the first such program in the U.S. This list contains only works of public art in outdoor public spaces, and not, for example, works inside museums. Most of the works mentioned are sculptures. Other kinds of art, i.e., sound installations, are marked as such next to their titles.
