Mary Fairchild MacMonnies Low (1858–1946), born in New Haven, Connecticut[1][2] was an American painter who specialized in landscapes, genre paintings, and portraits.

Mary Fairchild MacMonnies Low studied at the St. Louis School of Fine Arts (where she won a three years' scholarship), and in Paris at the Académie Julian and under Carolus Duran.

In April 1892, Low (then MacMonnies) was approached by Sarah Tyson Hallowell, agent for Bertha Palmer, the prime mover behind the Woman's Building at the World's Columbian Exposition, Chicago, 1893, to paint one of the two mural tympana planned for the building's interior.

The topic of Low's mural was Primitive Women and it was by all accounts at the time deemed to be the more successful of the two.

She also won a gold medal at Dresden in 1902, at Marseilles in 1905, and the Julia Shaw prize of the Society of American Artists in 1902.
