Mecca is a census-designated place (CDP) in Riverside County, California, United States. The population was 8,577 at the 2010 census, up from 5,402 at the 2000 census.
The unincorporated community is served by State Route 111, a north-south highway on the eastern shore of the Salton Sea.
Rapid growth in population, development and employment in the 2000s gave Mecca a new identity as the fastest growing area in California. A new public school complex, tens of thousands of new homes, a proposed commercial aviation airport in nearby Thermal and economic development as part of the Coachella Valley Free Enterprise Zone is positively contributing to living there.
