Pen Mar is an unincorporated community located in Washington County in the western part of the U.S. state of Maryland. The settlement lies on the Maryland–Pennsylvania state line, from which its name—derived from the contraction of “Pennsylvania‑Maryland”—originates.
Geography
Pen Mar is situated within the Appalachian Plateau region, at an elevation of approximately 1,200 feet (366 m) above sea level. The community is accessible via Maryland Route 68 (Pen Mar Road), which connects it to the nearby town of Hagerstown to the southeast and to the Pennsylvania border to the north.
Historical Overview
In the late 19th and early 20th centuries, Pen Mar became a popular resort destination known as Pen Mar Park. The park featured an amusement area, picnic facilities, and a scenic overlook of the surrounding hills, attracting visitors from the Hagerstown metropolitan area and beyond. The Maryland State Railway (later the Western Maryland Railway) operated a spur line that provided direct service to the park, contributing to its growth as a leisure spot.
The resort's popularity declined after World War II, and the railway service was discontinued. The Pennsylvania‑Maryland State Park, a small public park preserving part of the original resort grounds, remains a local historic site.
Demographics and Administration
As an unincorporated community, Pen Mar does not have a defined municipal government or its own census-designated population statistics. Residents are served by Washington County authorities and fall within the Hagerstown‑Frederick Metropolitan Statistical Area.
Education
Students residing in Pen Mar attend schools in the Washington County Public Schools system. Historically, the community was served by Pen Mar Elementary School, which operated until the mid‑20th century before consolidation into larger district schools.
Transportation

Legacy
Pen Mar’s legacy is primarily tied to its historical role as a regional resort and its position on the Maryland‑Pennsylvania border. The name continues to be used locally for geographic references, historical markers, and the remaining Pen Mar State Park.
