Susan Hannah Macdowell Eakins (September 21, 1851 – December 27, 1938) was an American painter and photographer. Her works were first shown at the Pennsylvania Academy of Fine Arts, where she was a student. She won the Mary Smith Prize there in 1879 and the Charles Toppan prize in 1882. One of her teachers was the artist Thomas Eakins, who later became her husband. She made portrait and still life paintings. She was also known for her photography. After her husband died in 1916, Eakins became a prolific painter. Her works were exhibited in group exhibitions in her lifetime, though her first solo exhibition was held after she died.
