Emil Tissot Mazy (December 27, 1865 — June 6, 1943) was a prominent California artist born in Rosée, Namur, Belgium. Perhaps the most widely viewed and referenced paintings still in existence today by Emil T. Mazy are those found on the proscenium and ceilings of the Spreckels Theater in San Diego, California, a building recognized in the National Register of Historic Places. The murals, as described by the Spreckels Theater website, feature "...two angels sprinkling a horn-of-plenty and Neptune bringing San Diego the riches of the ocean."
