Fishtown is a neighborhood in the River Wards section of Philadelphia, Pennsylvania. Located northeast of Center City Philadelphia, its borders are somewhat disputed today due to many factors, but are roughly defined by the triangle created by the Delaware River, Frankford Avenue, and York Street. Some newer residents expand the area to Lehigh Avenue, while some older residents shrink the area to Norris Street. It is served by the Market–Frankford Line rapid transit subway/elevated line of the SEPTA system. Fishtown is a largely working class Irish Catholic neighborhood, but it has recently seen a large influx of young urban professionals and gentrification.
