Parkhurst is a historic home at Harwood, Anne Arundel County, Maryland. It is a large two-story frame house with a complex floor plan, reflecting the evolution of the dwelling. The original Gothic Revival vernacular, center-passage, double-pile plan house was constructed about 1848-1850 by Richard S. Mercer. Alterations and additions were made in the early 20th century, giving the house a Neoclassical appearance. Also on the property are a timber framed mid-19th century smokehouse and an early-20th century frame tobacco barn. It was listed on the National Register of Historic Places in 2001. Tobacco barn was replaced in 2014
