Mayfair is a working class neighborhood in lower Northeast Philadelphia, Pennsylvania, United States, centered on the intersection of Cottman and Frankford Avenues.

First established in 1929, Mayfair came to fruition in the years following World War II as a community that provided fresher and more spacious living in an urban environment.

[citation needed] It was constructed over farmland surrounded by the established neighborhoods of Tacony, Holmesburg and Fox Chase.

Mayfair featured several groundbreaking concepts for city dwellers: bigger rowhouses with parking garages in the back.

Development in Mayfair was a forerunner to American suburbanization, an early part of the population shift from the inner city to its outer regions.

[7] As of the 2010 census, the tracts covering most of Mayfair[8] had a population of 38,202 people, 56% White, 19% African American, 16% Hispanic, 8% Asian, 2% Two or more races, and 2% Other and mostly in owner-occupied rowhouses.
