Art Deco (French: Exposition Internationale des Arts Decoratifs et Industriels Modernes) was a twentieth century movement in the decorative arts, that grew to influence architecture, design, fashion and the visual arts.

The name Art Deco derived from the Exposition Internationale des Arts Decoratifs et Industriels Modernes, a World's Fair held in Paris, France in 1925, though the term was not used prior to the late 1960s. Art Deco was influenced by many different cultures, particularly pre-World War I Europe.

The movement occurred at the same time as, and as a response to, the rapid social and technological advances of the early 20th century.

Paris was at the center of the high end of Art Deco design, epitomized in furniture by Jacques-Emile Ruhlmann, the best-known of Art Deco furniture designers and perhaps the last of the traditional Parisian ebenistes, and Jean-Jacques Rateau, the firm of Sae et Mare, the screens of Eileen Gray, wrought iron of Edgar Brandt, metalwork and lacquer of Jean Dunand, the glass of Rene Lalique and Maurice Marinot, clocks and jewelry by Cartier.

The term Art Deco was coined during the Exposition of 1925 but did not receive wider usage until it was re-evaluated in the 1960s.

Its practitioners were not working as a coherent community. It is considered to be an eclectic form of decorative Modernism, being influenced by a variety of sources.

Among them were the "primitive" arts of Africa, Egypt, or Aztec Mexico, as well as machine age technology such as the radio and skyscraper. These were expressed in fractionated, crystalline, faceted form of decorative Cubism and Futurism, in Fauvims' palette.
