Belmont Manor House, formally known as Belmont Plantation, is a two-story, five-part Federal mansion in Loudoun County, Virginia, United States, built between the years of 1799–1802 by Ludwell Lee (1760–1836), son of Richard Henry Lee. The land surrounding the mansion, the Belmont property, was handed down to his first wife (also his first cousin), Flora Lee, from their grandfather, Thomas Lee.

Located in the Belmont census-designated place, the Belmont Manor House and property have been owned since 1995 by Toll Brothers, Inc. It uses the Manor House as the clubhouse in a gated golf community. The property and house are listed in the National Register of Historic Places.
