Mary Stevenson Cassatt (May 22, 1844 - June 14, 1926) was an American painter and printmaker. She lived much of her adult life in France, where she first befriended Edgar Degas and later exhibited among the Impressionists.

Cassatt (pronounced ca-SAHT) often created images of the social and private lives of women, with particular emphasis on the intimate bonds between mothers and children.

Cassatt was born in Allegheny City, Pennsylvania, which is now part of Pittsburgh. She was born into favorable circumstances: her father, Robert Simpson Cassat (later Cassatt), was a successful stockbroker and land speculator, and her mother, Katherine Kelso Johnston, came from a banking family. The ancestral name had been Cossart. Cassatt was a distant cousin of artist Robert Henri. Cassatt was one of seven children, of which two died in infancy. Her family moved eastward, first to Lancaster, Pennsylvania, then to the Philadelphia area, where she began schooling at age six.
