Gustave Moreau (April 6, 1826 – April 18, 1898) was a French Symbolist painter. He was born and died in Paris.

Moreau's main focus was the illustration of Christian and mythological figures. As a painter of literary ideas rather than visual images, his images appealed to the imagination of some Symbolist writers and artists, who saw him as the precursor to their movement.

He became professor at École des Beaux-Arts of Paris in 1891 and counted among his many students the fauvist painters Henri Matisse and Georges Rouault.

He is buried in Paris at the Cimetière de Montmartre.
