Ryah Ludins (1896–1957) was a Ukrainian-born American muralist, painter, printmaker, art teacher, and writer. She made murals for post offices and other government buildings during the Great Depression and also obtained commissions for murals from Mexican authorities and an industrial concern. Unusually versatile in her technique, she made murals in fresco, mixed media, and wood relief, as well as on canvas and dry plaster. She exhibited her paintings widely but became better known as a printmaker after prints such as "Cassis" (1928) and "Bombing" drew favorable notice from critics. She taught art in academic settings and privately, wrote and illustrated a children's book, and contributed an article to a radical left-wing art magazine. A career spanning more than three decades ended when she succumbed to a long illness in the late 1950s.
