Potomac is a census-designated place in Montgomery County, Maryland, United States, named for the nearby Potomac River. In 2013, CNNMoney.com listed Potomac as the most affluent town in all the United States based on median house income. Potomac is also the seventh most top-educated American small town according to Forbes. In addition, Bloomberg Businessweek labeled Potomac as the twenty-ninth richest zip code in all of the United States in 2011 and had the largest population of any U.S. town to have a median income of more than $240,000. It is also tied with three other zip codes for the greatest concentration of the “1 percent” in America.
Potomac’s geographical focal point is Potomac Village, a small cluster of upscale shops and businesses at the intersection of Maryland State Highway 189 and Maryland State Highway 190. Each year during mid-October, local business and community participate in Potomac Day, a celebration of the community and the year’s happenings.
