Mulberry Fields is a historic home located at Beauvue, St. Mary's County, Maryland, United States. It was built about 1763, and is a large 2 1/2-story, 5-bay by 2-bay, hip-roofed brick house. On the front is a two-story Doric portico, built about 1820. The house is the only remaining Georgian "mansion-type" home in an area and has a panoramic view of the Potomac River, with a mile-long allee stretching downhill to the riverbank. Mulberry Fields was listed on the National Register of Historic Places in 1973.
