North Philadelphia, nicknamed North Philly, is a section of Philadelphia, Pennsylvania. It is immediately north of Center City. Though the full extent of the region is somewhat vague, "North Philadelphia" is regarded as everything north of either Vine Street or Spring Garden Street, between Northwest Philadelphia and Northeast Philadelphia. It is bordered to the north by Cheltenham Township along Cheltenham Avenue, Spring Garden Street to the south, 35th Street to the west and Adams Avenue to the east. The Philadelphia Police Department patrols five districts located within North Philadelphia: the 22nd, 25th, 26th, 35th and 39th districts. There are fifteen ZIP codes for North Philadelphia: 19120, 19121, 19122, 19123, 19125, 19126, 19130, 19132, 19133, 19134, 19137, 19138, 19140, 19141, and 19150. The city government views this sprawling chunk of Philadelphia more precisely as three smaller districts, drawn up by the Redevelopment Authority in 1964. These regions are (from north to south) Olney-Oak Lane, Upper North Philadelphia and Lower North Philadelphia. Other sections of North Philadelphia include Brewerytown, Fairhill, Fairmount, Fishtown, Francisville, Franklinville, Glenwood, Hartranft, Koreatown, Northern Liberties, Poplar (roughly bound by Girard Avenue, Broad Street, Spring Garden Street and 5th Street), Sharswood, Strawberry Mansion, and Yorktown.

The mansions of wealthy Philadelphians began to dot the landscape, and by the late 18th and early 19th century, several small town centers had developed to anchor the growing population. However, this suburban landscape was to be interrupted around the middle of the 19th century, as rapid urban expansion led to The Consolidation Act of 1854. This state law annexed all of the townships within Philadelphia County to the City of Philadelphia. With new territory now under the aegis of Philadelphia's city planners, a rising influx of European immigrants led to the end of North as a suburb of Philadelphia. North Philadelphia's decentralized towns were gradually meshed into a sprawling network of the ubiquitous Philadelphia rowhomes. Many of the newly created neighborhoods retained the name of their ancestral towns and townships, for example, Northern Liberties was formerly Northern Liberties Township.
