Santa Clarita (/ˌsæntə kləˈriːtə/; Spanish for "Little St. Clare") is a city in northwestern Los Angeles County in the U.S. state of California. With a 2020 census population of 228,673, it is the third-most populous city in Los Angeles County, the 17th-most populous in California, and the 103rd-most populous city in the United States.[11][9] It is located about 30 miles (48 km) northwest of downtown Los Angeles, and occupies 70.75 square miles (183.2 km2)[6] of land in the Santa Clarita Valley, along the Santa Clara River. It is a classic example of a U.S. edge city,[12] satellite city,[13] or boomburb.[14] Human settlement of the Santa Clarita Valley dates back to the arrival of the Chumash people, who were displaced by the Tataviam circa 450 AD. After Spanish colonists arrived in Alta California, the Rancho San Francisco was established, covering much of the Santa Clarita Valley. Henry Mayo Newhall purchased the Rancho San Francisco in 1875 and established the towns of Saugus and Newhall. The Newhall Land and Farming Company played a major role in the city's development. In December 1987, the city of Santa Clarita was incorporated, encompassing the communities of Canyon Country, Newhall, Saugus, and Valencia.[15] The four communities retain separate identities, and residents commonly refer to one of them when asked where they are from. Santa Clarita is bounded on the west by the Golden State Freeway (I-5). The Antelope Valley Freeway (CA-14) runs northeast–southwest forming part of the city's irregular east boundary. The two freeways meet at Newhall Pass, near the city's southernmost point.
