Sachio Yamashita (1933–2009) was a Japanese-American artist primarily known as the creator of more than 100 public murals throughout the Midwest between 1968 and 1982, and later as an abstract painter and muralist in the San Francisco Bay Area. As a muralist, Yamashita identified as an "environmental" artist "who creates, or alters environments." Chicago art historian Rebecca Zorach observes that Yamashita "showed how murals could be understood not just as community-based art but as huge environmental installations, breaking free from the gallery, changing city dweller's consciousness."
