Orange County is located in the Los Angeles metropolitan area in Southern 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 U.S., and more populous than 21 U.S. states. Although mostly suburban, it is the second most densely populated county in the state, behind San Francisco County.^[8] The county’s three most populous cities are Anaheim, Santa Ana, and Irvine, each of which has a population exceeding 300,000. Santa Ana is also the county seat. Six cities in Orange County are on the Pacific coast, including Seal Beach, Huntington Beach, Newport Beach, Laguna Beach, Dana Point, and San Clemente.

Orange County is included in the Los Angeles–Long Beach–Anaheim Metropolitan Statistical Area. The county has 34 incorporated cities. Older cities like Santa Ana, Anaheim, Orange, and Fullerton have traditional downtowns dating back to the 19th century, while newer commercial development or “edge cities” stretch along I-5 between Disneyland and Santa Ana and between South Coast Plaza and the Irvine Business Complex, and cluster at Irvine Spectrum. Although single-family homes make up the dominant landscape for most of the county, Northern and Central Orange County is relatively more urbanized and dense as compared to those areas beyond Irvine, which are less dense, though still contiguous and primarily suburban rather than exurban.

The county is a tourist center, with attractions like Disneyland, Knott’s Berry Farm, Mission San Juan Capistrano, Modjeska House, Segerstrom Center for the Arts, Yost Theater, Bowers Museum, Balboa Island, Angel Stadium, Downtown Santa Ana, Crystal Cove State Park, the Honda Center, and several popular beaches along its more than 40 miles (64 km) of coastline.

Members of the Tongva, Juaneño, and Luiseño Native American groups long inhabited the area. After the 1769 expedition of Gaspar de Portolà, a Spanish expedition led by Junipero Serra named the area Valle de Santa Ana (Valley of Saint Anne). On November 1, 1776, Mission San Juan Capistrano became the area’s first permanent European settlement. Among those who came with Portolá were José Manuel Nieto and José Antonio Yorba. Both these men were given land grants—Rancho Los Nietos and Rancho Santiago de Santa Ana, respectively. The Nieto heirs were granted land in 1834. The Nieto ranches were known as Rancho Los Alamitos, Rancho Las Bolsas, and Rancho Los Coyotes. Yorba heirs Bernardo Yorba and Teodosio Yorba were also granted Rancho Cañón de Santa Ana (Santa Ana Canyon Ranch) and Rancho Lomas de Santiago, respectively. Other ranchos in Orange County were granted by the Mexican government during the Mexican period in Alta California.
