Arlington County is a county in Virginia. It has so many buildings that it looks like a city. It is one of the smallest counties in the United States by area. It is across the Potomac River from Washington, D.C., and parts of it were once part of Washington. In 2020, 238,643 people lived there.[1] It is where many U.S. government offices are, such as The Pentagon. It is also the location of Arlington National Cemetery, which was built at the former plantation of Robert E. Lee, and the Ronald Reagan National Airport. ANC is where John F. Kennedy and many American soldiers are buried. Several battles of the American Civil War were fought in and around Arlington.
The District of Columbia was made with land contributed by Virginia and Maryland. In 1846, Congress agreed to give the land south of the Potomac back to Virginia. Most of the returned land became Arlington.

The District of Columbia itself, and Virginia's incorporated cities, are county equivalents. Virginia's incorporated cities are listed under their surrounding county. The incorporated cities bordering more than one county (Alexandria, Falls Church and Fredericksburg) are listed under the county they were part of before incorporation as a city. Some unincorporated areas and census-designated places like Silver Spring and Bethesda in Maryland, Reston in Virginia, as well as the County of Arlington in Virginia are also treated as city-like entities (or principal cities) even though they have not been legally incorporated as such. |
