Harriet Thayer Durgin (1843–1912) was a pioneering 19th-century American artist from the U.S. state of Massachusetts, who specialized in water colors and sketches of landscapes and still-lifes focused on botanical motifs. After studying in Paris, where she received special notice in the Salon of 1886, she shared a studio in Copley Square, Boston, with her sister, the muralist, Lyle Durgin. Durgin is remembered as one of the foremost American artists of the floral-painting genre during the late 19th and early 20th centuries.
