Gabriel Argy-Rousseau (born Joseph-Gabriel Rousseau) was a French glassmaker and one of the foremost exponents of the pâte de verre technique during the Art Deco era. He was born on March 17, 1885, in Mézières (now Charleville-Mézières, Ardennes).

After graduating from the National School of Ceramics in Sèvres, Paris, Rousseau worked as an engineer until 1914, when he patented his own proprietary recipe for glass paste. Shortly after the end of World War I, he established artistic production, and in 1921, in partnership with collector and entrepreneur Gustave-Gaston Moussier-Miton, he founded the "Les Pâtes de Verre d'Argy-Rousseau" workshop in Paris.

Argy-Rousseau crafted vases, lamps, sconces, powder boxes, and decorative panels featuring floral, zoomorphic, and mythological motifs. His palette spanned from soft pastel shades to deep, rich tones; a hallmark of his work was the seamless blending of colors paired with a velvety surface finish.
The workshop operated until 1931, when the economic hardships of the Great Depression forced its closure. After 1933, Argy-Rousseau continued to produce small series and one-of-a-kind pieces in his private studio until the end of his life.

Works by Argy-Rousseau are stored in the collections of the Musée des Arts Décoratifs in Paris, the Corning Museum of Glass in the USA, the Musée Lalique in Alsace, and numerous private collections worldwide.
