Shirlington is an unincorporated urban area, officially called an "urban village", in the southern part of Arlington County, Virginia, United States, adjacent to the Fairlington area. The word "Shirlington" is a combination of "Shirley" (from the Shirley Highway or Interstate 395) and "Arlington".
Shirlington is billed as "Arlington’s Arts and Entertainment District" and is largely mixed-use development based on New Urbanist principles. It is mostly middle-class residential, but like most of Arlington County has been experiencing an economic renaissance and is now home to many upscale dwellings and retail and service establishments that also serve the nearby Fairlington, Parkfairfax, Nauck and Long Branch Creek areas.
Shirlington lies in the valley of Four Mile Run, a tributary of the Potomac River. The land rises toward Fairlington in the south and Nauck in the north.
The area is bounded by I-395 on the east except for a small section of the city of Alexandria that lies to the west of the interstate. The only structure in that section, the Shirlington Gateway office building, has an Arlington address and is usually considered a part of Shirlington. To the north and west, starting in the east, Shirlington is bordered by South Glebe Road, 24th Street South, South Shirlington Road, South Four Mile Run Drive, and South Walter Reed Drive. On the west and south, starting in the west, Shirlington is bounded by South Arlington Mill Drive, the Arlington County Environmental Services facility, and the west side of Park Shirlington Apartments.
