Langley is an unincorporated community in the census-designated place of McLean in Fairfax County, Virginia, United States. The name "Langley" often occurs as a metonym for the Central Intelligence Agency (CIA), whose headquarters, the George Bush Center for Intelligence, is in Langley.
The land which makes up Langley today once belonged to Thomas Lee, former Crown Governor of the Colony of Virginia from 1749 to 1750. Lee's land was named Langley in honor of Langley Hall, which formed part of the Lee home estate in Shropshire, England. In 1839 Benjamin Mackall purchased 700 acres (283 ha) of land from the Lee family, while keeping the name.
