Westlake Village is an incorporated city located on the western edge of Los Angeles County, California, United States. The city, located in the region known as the Conejo Valley, encompasses half of the area surrounding Westlake Lake, and small neighborhoods primarily south of U.S. Route 101 and east of La Venta Drive. The population was 8,368 at the 2000 census. It is also the headquarters of the Dole Food Company. Westlake Village is known for its affluence and secluded character, and is considered one of the wealthiest communities in the Greater Los Angeles Area.

Westlake Village is a planned community built around an artificial lake straddling the Los Angeles-Ventura county line; it is a master-planned suburb of lakeside condos and suburban homes. Like neighboring Agoura Hills and Thousand Oaks, its mix of safe streets, good schools, picturesque hillsides, hiking, and equestrian trails attract residents seeking serenity.

The original community was divided by the Los Angeles and Ventura County boundary and known simply as "Westlake". The area located in Ventura County, or roughly two-thirds of the community, was annexed by the City of Thousand Oaks in two portions, in 1968 and 1972. In 1981, the remaining third eventually incorporated as the City of Westlake Village.

About 3,000 years ago, Chumash Indians moved into the region and lived by hunting rabbits and other game, and gathering grains and acorns. On-going excavations, archaeological sites, and polychrome rock paintings in the area provide a glimpse into the social and economic complexity of the ancient Chumash world. In 1770, Captain Gaspar de Portola led a party of Spanish explorers and missionaries, traveling north on the route that became known as El Camino Real. The party camped near a Chumash village, believed to be the site of present-day Westlake Village. Father Juan Crespi, chaplain and diarist of the expedition, wrote: “We are on a plain of considerable extent and much beauty, forested on all parts by live oaks and oak trees, with much pasturage and water.”

When the Spanish finally did settle the area, they were given huge land grants, the largest of which was Rancho Simi, given to the Pico family. When Mexico won independence from Spain in 1821, California became Mexican territory, and a few more land grants were given. When California was admitted to the union in 1850, most of the land that later became Ventura County was divided among only 19 families. The picturesque future Westlake Village site among rising knolls, arroyos, barrancas and ancient oaks was recognized as the central part of two Mexican land grants: Rancho El Conejo and Rancho Las Virgenes. In 1881, the Russell brothers purchased a large portion of the land for cattle ranching and in 1925 sold it to William Randolph Hearst. In 1943, the ranch was again sold to Fred Albertson. The Russell family leased back part of the land to continue its successful cattle ranch operation while the Albertson Company used the vast area as a movie ranch. Many movies and television shows were filmed here, including “Robin Hood,” “King Rat,” “Laredo,” and various episodes of “Tarzan,” “Buck Rogers,” “Gunsmoke,” and “Bonanza.”

In 1963, the American-Hawaiian Steamship Company bought the 12,000 acre (49 km²) ranch for $32 million and, in partnership with Prudential Insurance Company, commissioned the preparation of a master plan for a “city in the country.” Prominent architects, engineers, and land planners participated in designing the new community, a prominent example of planned 1960's-style suburbanism.

The original tract was divided by the Los Angeles/Ventura county line. In 1968 and 1972, the Ventura County side, two portions of Westlake Village consisting of 8,544 acres (35 km2), were annexed into the city of Thousand Oaks. In 1981, the Los Angeles County portion (3,456 acres or roughly 1/3) of the Westlake Village master community was incorporated as the City of Westlake Village. Today, a population of 8,893 resides within this city.
