Maryland City is a census-designated place (CDP) in Anne Arundel County, Maryland, United States. The population was 16,093 at the 2010 census. It is located east of Laurel, just over the border with Prince George's County. When the ZIP Code was created in 1963, United States Postal Service designated a large swath of land in western Anne Arundel County with 20724 "Laurel" despite none of 20724 being located in the City of Laurel, which is entirely in Prince George's County. Maryland City mostly consists of an older, compact housing development and is adjacent to Fort Meade army base. A large newer development on the north side of Maryland Route 198 is known as Russett and is included within the Maryland City CDP.
