Lansdowne, also known as Upper Deale or Lansdowne Farm, is a historic home and farm complex located at Centreville, Queen Anne's County, Maryland, United States. It consists of a brick dwelling, and a large barn, granary, and several outbuildings. The house was built in two distinct periods. The earliest house dates to the late colonial period and is a two-story, brick house, three bays wide and two rooms deep, with a single flush chimney on each gable. It is attached to a larger, Federal-period house built in 1823. The later house is brick, two and a half stories high, and was built directly adjoining the west gable of the earlier structure. Lansdowne was listed on the National Register of Historic Places in 1984.
