Annetta Johnson Saint-Gaudens (1869–1943) was an American sculptor, born in Flint, Ohio. She is best remembered for creating sculptures of "animals, children (and) fountains", but she also did the finishing carving on a "colossal marble figure", the allegorical sculpture Painting in front of the St. Louis Art Museum. She was also significant in the art world as being the wife of Louis Saint-Gaudens and the sister-in-law of Augustus Saint-Gaudens, with whom she studied and worked as an assistant.

Louis Saint-Gaudens was an American sculptor of the Beaux-Arts generation. He was the brother of renowned sculptor Augustus Saint-Gaudens; Louis later changed the spelling of his name to St. Gaudens to differentiate himself from his well-known brother.
