Mario Marenco (Foggia, September 9, 1933 - Rome, March 17, 2019) was an Italian comedian, humorist, actor, television author, and architect and designer. He graduated in architecture in 1957, in Naples, later obtaining research fellowships in Stockholm and Chicago. In 1960 he opened his own architecture and design atelier: Studio DEGW, based in Rome.

His activity in these areas, which he always pursued together with his artistic career, is evidenced by projects developed for well-known industries: the aluminum chandelier with references to Op art Cynthia, distributed in 1960 by Artemide, the 1970 Marenco sofa, designed for Arflex according to modular concepts, and in 1984 the Movie armchair, in the catalog for Poltrona Frau. Marenco also collaborated with the most important Italian car manufacturers in the creation of their exhibition stands.
