Georgia Totto O'Keeffe (November 15, 1887 – March 6, 1986) was an American artist.

Born near Sun Prairie, Wisconsin, Georgia O'Keeffe has been a major figure in American art since the 1920s. She received widespread recognition for her technical contributions, as well as for challenging the boundaries of modern American artistic style. She is chiefly known for paintings of flowers, rocks, shells, animal bones and landscapes in which she synthesized abstraction and representation. Her paintings present crisply contoured forms that are replete with subtle tonal transitions of varying colors. She often transformed her subject matter into powerful abstract images. Importantly, O'Keeffe played a central role in bringing an American art style to Europe at a time when the majority of influence flowed in the opposite direction. This feat enhanced her art-historical importance given that she was one of few women to have gained entry to this level of professional influence. She found artistic inspiration, particularly in New Mexico, where she settled late in life.

O'Keeffe was born in a farmhouse near Sun Prairie, Wisconsin. Her parents, Francis Calyxtus O'Keeffe and Ida Totto O'Keeffe, were dairy farmers. Her father was of Irish descent. Ida Totto's father, George Victor Totto, for whom Georgia O'Keeffe was named, was a Hungarian count who came to America in 1848. Through her mother, O'Keeffe was descended from Edward Fuller, one of the passengers on the Mayflower and a signer of the Mayflower Compact.
