Cornelius Grover Hicks (February 9, 1898 – September 13, 1930) was an American painter.
Cornelius was born in Massachusetts and was the first child of Job and Marilla Hicks to accomplish adulthood. He was a student at Pratt Institute and had showed tremendous power in the dome of art. In the 1920s, he painted two posters for the American Red Cross. He illustrated for several magazines, including Collier's Weekly.
Cornelius married Verna Bauer (1906–1995) in 1927 but had no children. He died in 1930 of Tuberculosis at the age of 32. Some of his paintings were passed upon to relations members, and a few of his works are yet owned by relatives of his.
