Margarett Williams Sargent (August 31, 1892 – 1978) was a noted painter in the Ashcan School and a follower of George Luks.

[2] After breaking a first engagement with Eddie Morgan, who was not accepted by her family, she trained as a sculptor in Italy, but later turned to watercolors and oils.

She was creating portraits of children and animals, but in 1917 decided to study with sculptor Gutzon Borglum.

[4]: 150  The sculptural portrait she did of Luks and entered in the Pennsylvania Academy annual show was praised by critics.

[5]: 10 Luks introduced her to John Kraushaar, a New York dealer whose Fifth Avenue gallery hosted Sargent's first solo exhibition in 1926.

[4]: 151 Her granddaughter, Honor Moore suggests she may have had an affair with her New York roommate, Marjorie Davenport.
