Germantown is an urbanized census-designated place in Montgomery County, Maryland. With a population of 86,395 as of the 2010 United States Census, Germantown is the third most populous place in Maryland, after the city of Baltimore, and the census-designated place of Columbia, Maryland. If Germantown were to incorporate as a city, it would become the second largest incorporated city in Maryland, after Baltimore. Germantown is located approximately 25 miles (40 km) outside of the U.S. capital of Washington, D.C., and is an important part of the Washington, D.C. Metropolitan Area.
The original plan for Germantown divided the area into a downtown and six town villages, namely Gunners Lake Village, Kingsview Village, Churchill Village, Middlebrook Village, Clopper's Mill Village, and Neelsville Village. The Churchill Town Sector at the corner of Maryland Route 118 and Middlebrook Road most closely resembles the downtown, or center, of Germantown, due to the location of the Upcounty Regional Services Center, the Germantown Public Library, the Black Rock Arts Center, the Regal Germantown Stadium 14, and a pedestrian shopping that features an array of restaurants. Three exits to Interstate 270 are less than one mile away, the Maryland Area Regional Commuter train is within walking distance, and the Germantown Transit Center that provides Ride On shuttle service to the Shady Grove station of the Washington Metro's Red Line.
Germantown has the assigned ZIP codes of 20874 and 20876 for delivery and 20875 for post office boxes. It is the most populous Germantown in Maryland and is the only "Germantown, Maryland" recognized by the United States Postal Service, even though there is one in Anne Arundel County, one in Baltimore County, and one in Worcester County.
