Greenbriar is a census-designated place in Fairfax County, Virginia, United States. The population as of the 2010 census was 8,166. The community between Fairfax City and Chantilly dates from the late 1960s, when it was developed by Levitt & Sons. The community is famous for having only one road within its territory that does not start with an "M" or "P", which is Acorn Hill (added in 1994 with the addition of five mansions to the community). A popular (but not proven) belief is that the roads were named after the architect's two children. One drawback for residents of the community is that with nearly identical sounding named roads (for example, Mayport and Maylock) in such close proximity to each other and house numbers being the same, the US Postal Service along with UPS and FedEx sometimes deliver items to the wrong house.
