Arnold Friedman (February 23, 1879 – December 29, 1946) was an American Modernist painter.

He was born in Corona, Queens, worked for the Federal Art Project and studied at the Art Students League of New York under the tutelage of Robert Henri and Kenneth Hayes Miller. In 1909, he took a six-month leave of absence from his job to study art in Paris.

During this time, he was introduced to the styles of Impressionism and Cubism. He exhibited with many of the most avant-garde venues and dealers of the period, including the Society of Independent Artists.
