Midway City is an unincorporated community and census-designated place (CDP) that forms part of the county land controlled by Orange County, California. The only area in Orange County that incorporates its chamber of commerce and homeowners association to act in concert like a city council, the area mostly is surrounded by Westminster with Huntington Beach bordering it on the southwest. Midway City was so named because it is horizontally midway between Seal Beach, to the west, and Santa Ana, to the east. The 2010 census listed the population as 8,485.
