Marion Greenwood (April 6, 1909 – August 20, 1970) was an American social realist artist who became popular starting in the 1920s and became renowned in both the United States and Mexico. She is most well known for her murals, but she also practiced easel painting, printmaking, and frescoes. She traveled to Mexico, Hong Kong, Burma, and India depicting peoples of different cultures and ethnicities and paying special attention to oppressed people in underdeveloped locations, which has at times resulted in critical reception in the modern-era due to issues of ethnic and racial stereotypes.
