John Anthony Baldessari (June 17, 1931 – January 2, 2020) was an American conceptual artist known for his work featuring found photography and appropriated images. He lived and worked in Santa Monica and Venice, California.

Initially a painter, Baldessari began to incorporate texts and photography into his canvases in the mid-1960s. In 1970 he began working in printmaking, film, video, installation, sculpture and photography. He created thousands of works which demonstrate—and, in many cases, combine—the narrative potential of images and the associative power of language within the boundaries of the work of art.
