Midway City is a census-designated place in the United States 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 its southwest boundary. Midway City was so named because it is horizontally midway between Seal Beach, to the west, and Santa Ana, to the east.
