Katharine Nash Rhoades (November 30, 1885 - October 26, 1965) was an American painter, poet and illustrator born in New York City.

Rhoades was a debutante in 1904, as was Malvina Hoffman,[2] with whom she traveled with Marion H. Beckett to Paris in 1908.

[6][7] She, along with Agnes Ernst Meyer and Marion Beckett were known as "the Three Graces" of the Alfred Stieglitz art circle.

[8] They were models for photographs by Stieglitz and Edward Steichen, paintings by Steichen, caricatures by Francis Picabia, drawings by Marius de Zayas, and paintings by Arthur Beecher Carles.

[1][14] The Meyers named their daughter, Katharine, the wife of Philip Graham and publisher of The Washington Post after her.

[17] She may have had a romantic relationship with Stieglitz,[18] or it may have been one-sided interest on his part,[19] before he met Georgia O'Keeffe.

[23] Rhoades died October 26, 1965, and was buried with her parents and other family members at the Hillside Burial Grounds in Sharon, Connecticut.
