Costa Mesa is a city in Orange County, California. Since its incorporation in 1953, the city has grown from a semi-rural farming community of 16,840 to a primarily suburban and edge city with an economy based on retail, commerce, and light manufacturing. The population was 109,960 at the 2010 United States Census.
Members of the Gabrieleño/Tongva and Juaneño/Luiseño nations long inhabited the area. After the 1769 expedition of Gaspar de Portolà, a Spanish expedition led by Junípero Serra named the area Vallejo de Santa Ana (Valley of Saint Anne). On November 1, 1776, Mission San Juan Capistrano became the area’s first permanent European settlement in Alta California, New Spain.
