The Surratt House (also known as the Mary Surratt House and the Surratt House Museum) is a historic house and house museum located at 9110 Brandywine Road in Clinton (formerly Surrattsville), Prince George's County, Maryland, United States. The house is named for John and Mary Surratt, who built it in 1852. Mary Surratt was hanged in 1865 for being a co-conspirator in the Abraham Lincoln assassination. It was acquired by the Maryland-National Capital Park and Planning Commission (M-NCPPC) in 1965, restored, and opened to the public as a museum in 1976.
