Raspberry Plain is a historic property in Loudoun County, Virginia, near Leesburg. Raspberry Plain became one of the principal Mason family estates of Northern Virginia, and was rebuilt in the early 20th century. It currently operates as an event site, hosting weddings and other special events year round.

Thomas Fairfax, 6th Lord Fairfax of Cameron granted the title to the 322-acre (130 ha) Raspberry Plain property to blacksmith Joseph Dixon in 1731. In 1754, the "houses, buildings, orchard, ways and watercourses" of Raspberry Plain were purchased by Loudoun County's first sheriff, Aeneas Campbell. Under Campbell's ownership, the property became the site of Loudoun County's first jailhouse.

George Mason's younger brother Thomson Mason purchased Raspberry Plain from Campbell in 1760. In 1771, Thomson built the mansion at Raspberry Plain. After Thomson's death, his eldest son Stevens Thomson Mason, inherited the house, and later became U.S. senator from Virginia. The Georgian-style mansion at Raspberry Plain was added to throughout the 19th-century, but demolished around 1910. Senator Mason's son, Armistead Thomson Mason, of Selma, was shot and killed by his cousin, John Mason McCarty, in a duel fought at the Bladensburg dueling grounds in Bladensburg, Maryland, in February 1819. McCarty lived at nearby Strawberry Plain, the home and jail of Aeneas Campbell, which had been parceled off from the Raspberry Plain property. That mansion has long since disappeared. In 1910, copper millionaire John Guthrie Hopkins rebuilt Raspberry Plain in the Colonial Revival style. Raspberry Plain, along with several neighboring estates including nearby Mason family estates Temple Hall and Locust Hill, is a contributing property in the 25,000-acre (100 km) Catoctin Rural Historic District, which was added to the National Register of Historic Places on 31 January 1989.

Although destroyed in 1910, the 1771 mansion that is depicted in old photographs appears to be a Georgian-style brick dwelling with gambrel-roofed brick wings. It was replaced by the present large Colonial Revival brick mansion around 1910. The 2+1⁄2-story, Flemish bond brick dwelling possesses a two-story tetrastyle Roman Doric portico with a lunette in the triangular pediment. A row of four pedimented dormers extends across the slate gable roof with overhanging eaves and a wide frieze with dentils encircles the building. Windows are six-over-six double-sash types with louvered shutters and wood lintels. A large central Palladian window sheltered by the portico is the dominant feature of the house. Several tenant houses, farm buildings, gambrel-roofed barns, a bank barn, and stables are scattered around the farm.
