Stagg Hall, is a historic home located at Port Tobacco, Charles County, Maryland, United States. It is a two-story frame house built about 1766 adjacent to Port Tobacco's former town square. It was built by Thomas Howe Ridgate, a prosperous Port Tobacco merchant. Stagg Hall was listed on the National Register of Historic Places in 1988. In 1903, Mary Lucilla Barbour purchased Stagg Hall from the William W. Padgett estate. After her death, her son, William Edgar Barbour, acquired the property from his father and siblings in 1934. In 1950, the heirs of William Edgar Barbour conveyed their interest in Stagg Hall to Robert Taylor Barbour and his wife, Phyllis, thus making them the owners of the property. Stagg Hall was acquired by the Charles County Government in 2013 for the price of $525,000.
