The Old Stone House is one of the oldest structures in Washington, D.C. The house is also the last pre-revolutionary colonial building in Washington, D.C. Built in 1765, Old Stone House is located at 3051 M Street, Northwest in the city's Georgetown neighborhood. Sentimental local folklore preserved the Old Stone House from being demolished, unlike many colonial homes in the area that were replaced by redevelopment.

The Old Stone House was constructed in three phases during the 18th century and is an example of vernacular architecture. The house was built as a one-story structure. Additions were later made, and it was used both as a residence and for business.

In the mid-20th century, at one time, it was the site of a used-car dealership. After acquisition and renovation by the National Park Service (NPS) in the 1950s, the Old Stone House was adapted as a house museum. The Old Stone House stands among the neighborhood's stores and restaurants. The building is considered part of the Rock Creek Parkway urban natural area and was listed on the National Register of Historic Places in 1973. The Old Stone House is also a contributing property to the Georgetown Historic District, a National Historic Landmark. Today, the home is 85% original to its 18th-century construction.
