About Santa Ana

Santa Ana (Spanish for 'Saint Anne') is the county seat of Orange County, California. Located in the Greater Los Angeles region of Southern California, the city's population was 310,227 at the 2020 census, making Santa Ana the second most populous city in Orange County (after Anaheim), the 13th-most populous city in California, and the 64th densest large city in the United States. Santa Ana is a major regional economic and cultural hub for the Orange Coast. Santa Ana's origins began in 1810, when the Spanish governor of California granted Rancho Santiago de Santa Ana to José Antonio Yorba. Following the Mexican War of Independence, the Yorba family rancho was enlarged, becoming one of the largest and most valuable in the region and home to a diverse Californio community.
