Mary's Mount is a historic home at Harwood, Anne Arundel County, Maryland, United States.

The earliest portion of Mary's Mount was built in 1771 for Col. Richard Harwood as a 1+1⁄2-story gambrel roof structure.

Jacob Wheeler Bird enlarged the house to its present two-story height in the early 19th century.

The enlargements included two northern additions, each section of which is lower than its neighbor to the south, creating a "telescope" effect.
