Melwood Park is a historic home located near Upper Marlboro in Prince George's County, Maryland, United States.

[1] The house is significant for its early owners, some of the most prominent men in all phases of the life of colonial Maryland; the Digges, Carroll, and Lee families.

[2] Recent dendrochronology performed on the roof rafters of Melwood Park suggest an earlier construction date.

The original Melwood Park land patent was for 1,050 acres (4.2 km2) of which half were eventually inherited by the Digges family.

These changes include; extending the dwelling on the east by 6 feet (1.8 m) and on the west by 12 feet (3.7 m), extending the loft to a full story across the south facade only, the addition of two outward flanking chimney stacks, encasing the south facing facade with brick nogging and a veneer brick, adding 16/16 common sliding sash windows of the first floor and 9/9 common sliding sash windows on the second floor.

The veneer brick and addition of solid masonry were set in an artful Flemish bond pattern with glazed headers, queen course and oyster shell lime mortar with a grapevine joint.

During this expansion it is assumed that the northward ell was not modified, however this portion of the building was removed in a subsequent renovation likely to have occurred circa 1897.
