Orange County is a county in the U.S. state of California. As of the 2010 census, the population was 3,010,232 making it the third-most populous county in California, the sixth-most populous in the United States, and more populous than twenty-one U.S. states. Its county seat is Santa Ana. It is the second most densely populated county in the state, second only to San Francisco County. The county's four largest cities, Anaheim, Santa Ana, Irvine, and Huntington Beach each have populations exceeding 200,000. Several of Orange County's cities are on the Pacific coast, including Huntington Beach, Newport Beach, Laguna Beach, and San Clemente.

Orange County is included in the Los Angeles-Long Beach-Anaheim, CA Metropolitan Statistical Area. Thirty-four incorporated cities are located in the county; the newest is Aliso Viejo, which was incorporated in 2001. Anaheim was the first city, incorporated in 1870, when the region was still part of neighboring Los Angeles County. Whereas most population centers in the United States tend to be identified by a major city, there is no defined urban center in Orange County. It is mostly suburban except for some traditionally urban areas at the centers of the older cities of Anaheim, Fullerton, Huntington Beach, Orange, and Santa Ana. There are several edge city-style developments such as Irvine Business Center, Newport Center, and South Coast Metro.
