Harriet Hallowell (1873–1943) was an expatriate American artist who lived in France for fifty years. She was born in Boston to a Quaker family. During World War I she remained in France and volunteered at a hospital. The hospital was near the home she shared with her aunt Sarah Tyson Hallowell, located in the village of Moret-sur-Loing, which borders the Forest of Fontainebleau. Because of her war relief efforts on behalf of the French and Allied soldiers, the French government awarded her the Légion d'honneur in 1930.
