Concord is a historic home located in District Heights, Prince George's County, Maryland. It is a 1790s 2 1⁄2-story Flemish bond brick house with a five-bay south facade, and a later two-part wing which stretches to the west. The home was built for Zachariah Berry, Sr. (1749-1845), a prosperous planter who had large landholdings in Maryland, the District of Columbia, and Kentucky. A great deal of the home's features are Greek Revival-influenced, dating from an 1860s renovation. A family cemetery and a number of 20th century outbuildings are located on the property.
Concord was listed on the National Register of Historic Places in 1982.
