North Fair Oaks is a census-designated place and an unincorporated area located in San Mateo County, California adjacent to Redwood City, Atherton, and Menlo Park.

The larger area including North Fair Oaks and adjacent parts of Redwood City has a large Hispanic/Latino population and is known locally as Little Mexico.

The neighborhood is distinctive, as it is one out of only three communities (the others being East Palo Alto and Pescadero) in San Mateo County that also have a majority-Hispanic/Latino population.

One of the two Hetch Hetchy Aqueduct utility corridors on the San Francisco Peninsula was installed through the area at an angle diagonal to the existing street grid.

This local microclimate is centered on nearby Redwood City which claims the slogan "climate best by government test".

Essential services are provided through San Mateo County by the Board of Supervisors using input from the North Fair Oaks Community Council.

FOBA is a not-for-profit 501c3 organization that has raised funds to plant trees and install traffic-calming devices throughout the neighborhood.

Its primary activity is to maintain the neighborhood park at Edison Way and Fair Oaks Avenue.
