North Potomac

North Potomac is a census-designated place and an unincorporated area in Montgomery County, Maryland, United States.

North Potomac was created in 1988 from the peripheral fringes of Gaithersburg and Rockville, and lies parallel to the Potomac River. North Potomac shares ZIP codes with Gaithersburg and Rockville. The United States Postal Service defines North Potomac to encompass only zip code 20878.

Having only been established in the late 1980s, North Potomac still maintains a burgeoning neighborhood feel and remains largely residential. Located 20 miles northwest of Washington, D.C. and flanked by Gaithersburg to the north, Rockville to the east and Potomac to the south, this neighborhood houses mainly families seeking quiet suburban life outside of the city.
