Émile Gallé (May 8, 1846, Nancy – September 23, 1904, Nancy) was a French artist who worked in glass, and is considered to be one of the major forces in the French Art Nouveau movement.

Gallé was the son of a faience and furniture manufacturer and studied philosophy, botany, and drawing in his youth. He later learend glassmaking at Meisenthal and came to work at his father's factory in Nancy following the Franco-Prussian War. His early work was executed using clear glass decroated with enamel, but he soon turned to an original style featuring heavy, opaque glass carved or etched with plant motifs. His career took off after his work received praise at the Paris Exhibition of 1878.

Within a decade of another successful showing at the Paris Exhibition of 1889, Gallé had reached international fame and his style, with its emphasis on naturalism and floral motifs, was at the forefront of the emerging Art Noveau movement. He continued to incorporate experimental techniques into his work, such as metallic foils and air bubbles, and also revitalized the glass industry by establishing a workshop to mass produce his, and other artist's, designs. The factory would employ 300 workers and artisans at its height, including the notable glassmaker Eugène Rosseau , and remain in operation until 1913. Gallé also branched off into furniture design, with his pieces drawing heavily from the Rococo concept of emphasizing constructive points organically and featuring inlay and carving in a floral style.

Gallé wrote a book on art entitled Écrits pour l'art 1884-89 ("Writings on Art 1884-89"), which was published posthumously in 1908.
