Lawrence Park (December 16, 1873 – September 28, 1924) was an American art historian, architect, and genealogist who authored pioneering critical and biographical studies of portrait painters Gilbert Stuart, Joseph Badger, and Joseph Blackburn, active during the colonial and early federal periods of the United States.

Aided by family wealth, Park gave up his business in 1914 to focus on his historical and curatorial work.

[2] Next, Park began researching early American portrait painters, traveling to view their works and making detailed notes and pencil sketches.

Per art historian David Meschutt, his "thoroughly researched publications, each containing a biographical sketch of the artist and a catalog of his paintings, are the definitive studies of both painters.

"[1] Park's magnum opum, a four-volume biography and descriptive catalog of renowned American portraitist Gilbert Stuart, was completed and published posthumously in 1926.
