Robert William Gadbois (fl. c. 1940 - 1960) was an artist active in the United States and Canada during the mid-20th century. After receiving his M.F.A. from the University of Iowa in 1950, Gadbois began teaching art at the University of Winnipeg along with three other new hires from Iowa. Gadbois and his contemporaries reenergized the art program in Winnipeg and drove a new interest in modern and surrealist art.
