Augustus (August) Saint-Gaudens, born on March 1, 1848, in Dublin, died on August 3, 1907, in Cornish, New Hampshire, was an American sculptor.

Saint-Gaudens' father was French, his mother Irish; the family moved to North America during his childhood. He studied in Paris from 1867 to 1870 under Jouffroy and Mercié, accompanied the latter to Italy, stayed there for three years, and then worked in the United States, where he became the country's foremost representative of modern sculpture. His major works in the monumental field include the monument to David Farragut in New York, equestrian statues of Generals Logan (Chicago), Shaw (Boston), and Sherman (New York), all powerful and realistic artworks. Additionally, he created monuments to Lincoln (in Chicago) and Deacon Chapin (in Springfield). He also produced solid works in the field of the nude. Nevertheless, he achieved his very best in relief and plaque work—an exquisite example is the large bronze relief Amor caritas (Luxembourg Museum, Paris). His praise and works are discussed in a monograph by Royal Cortissoz (Boston, 1908).
