Oscar Bluemner (June 21, 1867 – January 12, 1938), born as Friedrich Julius Oskar Blümner and since 1933, known as Oscar Florianus Bluemner, was a German-born American Modernist painter.

Often overlooked in his lifetime, Bluemner now is widely acknowledged as a key player in the creation of American artistic Modernism, with better-known colleagues such as Georgia O'Keeffe and John Marin.
