Musée des Arts Décoratifs (Museum of Decorative Arts), a museum of the decorative arts and design, located in the Palais du Louvre's western wing, known as the Pavillon de Marsan, at 107 rue de Rivoli, in the 1st arrondissement of Paris, France. It is one of three museum locations of Les Arts Décoratifs.
The museum also hosts exhibitions of fashion, advertising and graphic art from its collections from the formerly separate but now defunct Musée de la Publicité and Musée de la mode et du textile.
The museum collection was founded in 1905 by members of the Union des Arts Décoratifs. The architect was Gaston Redon. It houses and displays furniture, interior design, altar pieces, religious paintings, objets d'arts, tapestries, wallpaper, ceramics and glassware, plus toys from the Middle Ages to the present day.
The collection is primarily composed of French furniture, tableware, carpets such as those from Aubusson, porcelain such as that by the Manufacture nationale de Sèvres, and a large number of glass pieces by René Lalique, Émile Gallé and many others. It includes numerous works in the Art Nouveau and Art Déco styles and modern examples by designers like Eileen Gray and Charlotte Perriand. However, the museum's deep holdings range back to 13th-century Europe.
