Thousand Oaks is the second-largest city in Ventura County, California, United States. It is in the northwestern part of Greater Los Angeles, approximately 40 miles (64 km) from Downtown Los Angeles, and is less than 15 miles (24 km) from the Los Angeles neighbourhood of Woodland Hills. It is named after the many oak trees present in the area.
The city forms the central populated core of the Conejo Valley. Thousand Oaks was incorporated in 1964, but has since expanded to the west and east. Two-thirds of master-planned community of Westlake and most of Newbury Park were annexed by the city during the late 1960s and 1970s. The Los Angeles County–Ventura County line crosses at the city's eastern border with Westlake Village.
A number of high-tech companies moved to Newbury Park in the 1960s. Today it is home to a number of high-tech and biotech companies, and has been dubbed "the next Silicon Valley" for this reason. Thousand Oaks has been named one of the wealthiest cities in the United States.
