Langley, Virginia

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), as the community is home to the CIA headquarters, the George Bush Center for Intelligence. 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.

The community was essentially absorbed into McLean many years ago, although there is still a Langley High School. In addition to its roles as a bedroom community for Washington, D.C., and as home to the CIA's headquarters, the area is the site of the Federal Highway Administration's Turner-Fairbank Highway Research Center and formerly the Claude Moore Colonial Farm of the National Park Service, now permanently closed.
