Fishtown is a neighborhood in Philadelphia, Pennsylvania, United States. Located immediately northeast of Center City, 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 Linerapid transit subway/elevated of the SEPTA system. Fishtown is known as a working class Irish Catholic neighborhood.
The name comes from the fact that a number of 18th and early 19th centuries German and German-American families bought up the fishing rights on both sides of the Delaware River from Trenton Falls down to Cape May, New Jersey. Also, in the early 18th century, an English colonist was fabled to have caught the largest shad in the world in the Delaware River.
