Darnestown is a United States census-designated place (CDP) and an unincorporated area in Montgomery County, Maryland. The CDP is 17.70 square miles (45.8 km²) with the Potomac River as its southern border and the Muddy Branch as much of its eastern border. Seneca Creek borders portions of its north and west sides. The Travilah, North Potomac, and Germantown census-designated places are adjacent to it, as is the city of Gaithersburg. Land area for the CDP is 16.39 square miles (42.4 km²). As of the 2020 census, the Darnestown CDP had a population of 6,723,^[2] while the village of Darnestown is considerably smaller in size and population. Downtown Washington, D.C. is about 22 miles (35 km) to the southeast.

Within the Darnestown census-designated place at the intersection of what is now Darnestown Road and Seneca Road, the small village of Darnestown has existed since about 1800. The community had a population of 200 in 1878. The name Darnestown comes from William Darne, who owned the most land in the area at the beginning of the 19th century when the community post office opened. Settlement in the area began around 1750, and the tiny community was called Mount Pleasant, and then Darnes, before the name Darnestown began being used. The community thrived in the 19th century during the golden years of the Chesapeake and Ohio Canal, as the improved transportation facilities offered area farmers access to more markets. In the 1880 census, the United States Census Bureau began using a Minor Civil Division (MCD) category for aggregating populations, and the new Darnestown district had about 1,500 people. Growth stopped late in the 19th century when a new railway bypassed the community.

In the 1960s, affluent families began buying Montgomery County farmland for new housing and equestrian purposes. Today, many Darnestown CDP residents are wealthy and live in large homes on large lots, which is reflected in their high average income and low housing density. The median household income is nearly $228,000, and 73 percent of residents aged 25 years or more have at least a bachelor's degree or higher. The community benefits from its proximity to workplaces such as the Shady Grove Hospital area and the I-270 Technology Corridor. Washington is accessible by automobile or public transportation. Beginning with the 2000 census, the Census Bureau created a Darnestown census-designated place.
