* Unincorporated communities are not independent municipalities or jurisdictions. They have no local government other than that by the County. All local public services are received from the County. Communities listed above are all "Census Designated Places" according to the U.S. Census Bureau. These are not incorporated cities or towns, but are identified as significantly populated communities for the purposes of the census.

† The formerly unincorporated communities of Newhall and Valencia became part of the city of Santa Clarita, incorporated in 1987.
