Kensington is a neighborhood located in the United States city of Philadelphia, Pennsylvania. It is located between the Lower Northeast section of Philadelphia and North Philadelphia. Not to be confused with the former Kensington District, now commonly referred to as Fishtown, the area modernly referred to as "Kensington" is more of a section of smaller sub-neighborhoods than a clearly defined area. As such, there are disputes among locals as to the boundaries of the area. Generally-accepted boundaries are the triangular area bounded by Erie Avenue to the north, Front Street (and sometimes Fifth Street) to the West and Trenton Avenue to the East. Within these boundaries, sub-neighborhoods include Harrowgate, Lower Kensington, West Kensington and Fishtown. Due to colloquial changes in the boundaries of the area since the Act of Consolidation, 1854, no clear definition is possible. The Greater Kensington area of the city roughly coincides with the former Kensington District, Richmond District, Aramingo Borough and Northern Liberties Township. Since incorporation into the City of Philadelphia (see Act of Consolidation, 1854), these areas have evolved over time to include portions of the modern "Kensington". The area is located just a couple of miles northeast of Center City and just to the West of the Port Richmond neighborhood.

Kensington is home to a large population of Irish Americans, Hispanic Americans, mainly Puerto Ricans and Dominicans, African Americans, and Polish Americans.

In the nineteenth century, Kensington was one of the leading centers of the textile industry, particularly in carpet manufacture. McNeil Laboratories began with the purchase of a pharmacy in the area in 1879 by the company's namesake.

Deindustrialization eventually took its hold on the neighborhood in the 1950s, leading to a significant population loss, high unemployment, economic decline, and the abandoning of homes in the neighborhood. However, some sections of the neighborhood have been revitalized in recent years, especially those near Frankford Avenue, Kensington's neighbor North of Lehigh Avenue, and Fishtown, an area of Kensington where many Shad fisheries were located, another traditionally working class neighborhood which has seen rents increase. While most of the large manufacturers have left, the area has many small shops and large renovated factories and warehouses for newer artisans to set up shop.

The U.S. Postal Service designates Kensington as ZIP codes 19125 (Kensington Station) and 19134 (Richmond Station). Adjacent neighborhoods are Northern Liberties, Fishtown, Port Richmond, Juniata, and Frankford.

Kensington is noted as the childhood home of fictional Cold Case character Lily Rush.

A small minority of the residents of Kensington refer to themselves as "Kenzos." The term can be used both derogatorily and affectionately
