Which art movement is Georgia O'Keeffe most commonly associated with?

Georgia O'Keeffe is most commonly associated with American modernism.

Her work helped define an American form of modernist painting during the early and middle twentieth century. She used enlarged flowers, abstract shapes, New York architecture, animal bones, and Southwestern landscapes as subjects, often simplifying them into bold forms and carefully controlled color areas.

O'Keeffe did not work in only one style throughout her career. Her early charcoal abstractions were among the first purely abstract works produced by an American artist, while later paintings moved between recognizable subjects and increasingly reduced forms. This variety is why labels such as abstraction, precisionism, and regional modernism can also appear in discussions of her art.

She is sometimes incorrectly classified as a Surrealist because some paintings contain dreamlike scale or unexpected juxtapositions. However, O'Keeffe was not a formal member of the Surrealist movement. Her work is generally placed within American modernism, a broad category rather than a single technique or school.
