McLean is an unincorporated community and census-designated place (CDP) in Fairfax County in Northern Virginia. McLean is home to many diplomats, businessmen, members of Congress, and high-ranking government officials partially due to its close proximity to Washington, D.C. and the Central Intelligence Agency. It is the location of Hickory Hill, the former home of Ethel Kennedy, the widow of Robert F. Kennedy. It is also the location of Salona, the former home of Light-Horse Harry Lee, the Revolutionary War hero. It is located between the Potomac River and the town of Vienna. McLean is known for its luxury homes and its nearby high-end shopping destinations: the Tysons Corner Center and the Tysons Galleria.
The community lies in the Piedmont upland on the west bank of the Potomac River. The river forms the community’s northern and eastern borders, and a number of its smaller tributaries flow north and northeast through the CDP. From west to east, these include Bull Neck Run, Scott Run, Dead Run, Turkey Run, and Pimmit Run.
As a suburb of Washington, D.C., McLean is a part of both the Washington Metropolitan Area and the larger Baltimore-Washington Metropolitan Area. The CDP includes the unincorporated communities of Langley, Lewinsville, and West McLean.
The two McLean zip codes – 22101 and 22102 – are among the most expensive ZIP Codes in Virginia and the United States.
