Lansdowne, Greek Revival residence in Adams County, United States.

Lansdowne is a Greek Revival plantation house built in 1852–1853 for Charlotte Hunt and George Matthews Marshall, a Princeton graduate, on a 727-acre estate. The house and 120 acres of the original property remain in the hands of the builders' descendants, who open it periodically for tours. It stands on M.L. King Jr. Road, one mile north of the Natchez city limits, and adjoined the Homewood estate.

The land was earlier the Nathaniel Ivy tract, later Robert Dunbar's home, and passed through Dunbar's descendants to Charlotte Hunt. In 1852–1853 Charlotte and her husband George Matthews Marshall, a Princeton graduate, built the Greek Revival house on 727 acres and named the estate after the Marquess of Lansdowne. After the Civil War it continued as a cotton plantation producing cotton, corn, sheep and cattle until about 1960.

The estate is named after the Marquess of Lansdowne, an English acquaintance of the Marshalls, a nod to wealthy Southern planter families' wish to imitate English aristocratic life. Susan Gruby Washington, abducted from Guinea and enslaved here, stayed on after emancipation as nurse to the Marshall children, living in two rooms above the kitchen building; she died in 1918 and is buried in the family cemetery on the grounds.

The residence is registered in the National Register of Historic Places and can be viewed from the exterior. It serves as a good reference point for anyone interested in learning about American architecture from the 19th century.

The house and 120 of the original 727 acres remain in the hands of the builders' descendants, who open the property periodically for tours. The land passed to Charlotte Hunt through Robert Dunbar, whose family held it before it was called Lansdowne.
