Mário Raul de Morais Andrade (October 9, 1893 – February 25, 1945) was a Brazilian poet, novelist, musicologist, art historian and critic, and photographer. He wrote one of the first and most influential collections of modern Brazilian poetry, Paulicéia Desvairada (Hallucinated City), published in 1922.

He has had considerable influence on modern Brazilian literature, and as a scholar and essayist—he was a pioneer of the field of ethnomusicology—his influence has reached far beyond Brazil. Andrade was a central figure in the avant-garde movement of São Paulo for twenty years. Trained as a musician and best known as a poet and novelist, Andrade was personally involved in virtually every discipline that was connected with São Paulo modernism.
