Giovanni "Gio" Ponti (18 November 1891 – 16 September 1979) was an Italian architect, industrial designer, furniture designer, artist, teacher, writer and publisher.

During his career, which spanned six decades, Ponti built more than a hundred buildings in Italy and in the rest of the world. He designed a considerable number of decorative art and design objects as well as furniture. Thanks to the magazine Domus, which he founded in 1928 and directed almost all his life, and thanks to his active participation in exhibitions such as the Milan Triennal, he was also an enthusiastic advocate of an Italian-style art of living and a major player in the renewal of Italian Design after the Second World War. From 1936 to 1961, he taught at the Milan Polytechnic School and trained several generations of designers. Ponti also contributed to the creation in 1954 of one of the most important design awards: the Compasso d'Oro prize. Ponti died on 16 September 1979.

His most famous works are the Pirelli Tower, built from 1956 to 1960 in Milan in collaboration with the engineer Pire Luigi Nervi, the Villa Planchart in Caracas and the Superleggera chair, produced by Cassina in 1957
