Potomac Heights is a census-designated place (CDP) in Charles County, Maryland, United States.

[2] It has a volunteer fire department and numerous older rambler homes built for workers at the nearby U.S. Navy munitions plant in Indian Head (now known as the Indian Head Naval Surface Warfare Center).

In 1947, the residents of Potomac Heights formed a co-operative and purchased the entire community from the previous owners (the US government).

The largest co-operative, Greenbelt, located in adjoining Prince George's County, evolved from one of three planned communities (Greendale, Wisconsin, and Greenhills, Ohio) and developed as a federally supervised experiment in cooperative living under the New Deal during the Roosevelt administration.

[discuss] Hillwood Square Mutual in Falls Church, Virginia, was built to house workers at the Torpedo Factory in Alexandria.
