West Philadelphia, nicknamed West Philly, is a section of Philadelphia, Pennsylvania. Though there is no official definition of its boundaries, it is generally considered to reach from the western shore of the Schuylkill River, to City Avenue to the northwest, Cobbs Creek to the southwest, and the SEPTA Media/Elwyn Line to the south. An alternate definition includes all city land west of the Schuylkill; this would also include Southwest Philadelphia and its neighborhoods.
