Arlington County is a county in the Commonwealth of Virginia. It is coterminous with the US Census Bureau-census-designated place of Arlington, which is the second-largest principal city of the Washington metropolitan area. As a result, the county is often referred to in the region simply as "Arlington" or "Arlington, Virginia". In 2014, the county's population was estimated to be 229,302
Arlington is named for the Arlington estate associated with the Washington, Custis and Lee families. The estate, in turn, was named for the original Arlington estate in Northampton County, Virginia established sometime before 1680, which was, in turn again, named for the Baron Arlington.

Arlington County was originally named Alexandria County. It was formed from a part of Fairfax County that was ceded to the US government in 1789 but was returned to Virginia in 1846. The county name was changed in 1920 to Arlington, the name of the Custis family mansion (former home of Robert E. Lee), which is located in the county. Its area is 25 square miles, and the county seat is Arlington. The population is 189,453 according to the 2000 census. Pre-1920 records belong to Alexandria and Fairfax Counties and the District of Columbia.
As reported by the Census Bureau, the county has a total area of 26.1 square miles (67.6 km2), of which 26.0 square miles (67.3 km2) is land and 0.1 square miles (0.3 km2) (0.4%) is water. It is the smallest county by area in Virginia and among the smallest by land area in the United States. About 4.6 square miles (11.9 km2) of the county is federal property. The county is roughly in the shape of a rectangle 4 miles (6.4 km) by 6 miles (9.7 km), with the small end slanting in a northwest-southeast direction. It has no incorporated areas. Its county seat is the census-designated place (CDP) of Arlington, which is coterminous with the boundaries of the county; however, the county courthouse and most government offices are located in the Courthouse neighborhood.
