River Farm was a division of George Washington's Mount Vernon, located along the Potomac River. Washington purchased part of the property from a neighbor, William Clifton. Washington changed the name of Clifton's Neck to River Farm and leased the property to tenant farmers. River Farm was one of the five farms that made up Mount Vernon: Mansion House, Dogue Run, Muddy Hole, River, and Union, plus a gristmill and distillery. Each site had its own overseers, enslaved workers, livestock, equipment, and buildings.
River Farm was passed down through two immediate generations of Washingtons and later sold with 652 acres of Washington's original land to the Snowden brothers of New Jersey. A portion of the Mount Vernon's River Farm later became home to the American Horticultural Society (AHS) headquarters.
