Eugenia Belín Sarmiento (December 29, 1860, San Juan, Argentina - August 2, 1952, Buenos Aires, Argentina) was an Argentinean painter and author. Her works were featured in various international shows, among them the first Exposición Anual de Pintura, Dibujo y Escultura (Annual Exhibition of Painting, Drawing, and Sculpture) for artists of South America in 1893. Critical response to her works has often focused attention on her portraits of her grandfather, Domingo Faustino Sarmiento, who was president of Argentina from 1868 to 1874. Eugenia completed many other works as well, including miniatures as well as full size portraits, paintings of flowers, birds, and still lives, and sculptures.
