Black Walnut is a historic plantation house and farm located near Clover, Halifax County, Virginia. The main house was built in at least three sections beginning about 1774 to 1790. In the 1840s and 1850s, a substantial two-story frame addition was built in two stages parallel to the existing house, along with a connecting hyphen, altogether giving the house an H-shape. The interior features Greek Revival style details. During the September 1939 National Tobacco Festival, Academy Award Winner Mary Pickford visited Black Walnut as Queen of the festival.
