Patricia DuBose Duncan was an American artist who lived in Topsham, Maine. She is best known for her work to gain support for designating some of the last remaining tall grass prairie land in the American Midwest, as the Tallgrass Prairie National Preserve. This land was publicized in a Smithsonian Traveling Exhibition (S.I.T.E.S.) in 1976-86 as a Bicentennial Exhibition. The exhibit has been digitally preserved by Kansas State University's Marianna Kistler Beach Museum of Art.
