Emilio Pucci, Marchese di Barsento (Italian pronunciation: [eˈmiːljo ˈputtʃi]; 20 November 1914 – 29 November 1992) was an Italian aristocrat, fashion designer and politician. He and his eponymous company Pucci designed geometric prints in many colors.

Pucci was born in Naples in 1914 to the Pucci family, and he lived and worked in the Pucci Palace in Florence for much of his life.

At the age of 17 Pucci traveled to Lake Placid, New York, as part of the Italian team at the 1932 Winter Olympics, where he did not compete. After two years at the University of Milan, he studied agriculture at the University of Georgia in Athens, Georgia, United States. In 1935, he was given a full scholarship to Reed College in Oregon in return for developing a college ski team. He earned an MA in social science from Reed College in 1937, and was awarded his doctorate (laurea) in political science from the University of Florence in 1941.

In 1938, Pucci joined the Italian Air Force, and served as an SM.79 torpedo bomber pilot during World War II, rising to the rank of captain and receiving decorations for valour. During the war he became a confidant of Benito Mussolini's eldest daughter, Edda, and played a key role in a plan to save the life of her husband, Mussolini's former Foreign Minister, Count Galeazzo Ciano, who was on trial for his part in the removal of Mussolini from power in 1943. The plan involved delivering some of Ciano's papers (which were highly critical of Mussolini) to the Gestapo so that they could be bartered for Ciano's life.

After Adolf Hitler vetoed the scheme, Pucci drove Edda to the Swiss border on 9 January 1944 and ensured her escape. Before departing, Edda wrote last pleas to Hitler, Mussolini, and General Wilhelm Harster, the SD commander in Italy, and Pucci delivered these letters to an intermediary. He then attempted to flee to Switzerland himself, but he was arrested and transported to San Vittore prison in Milan, where he was tortured by the Gestapo in a futile attempt to extract information. Pucci then managed to escape and reach Switzerland, where he remained until the end of the war.

The first clothes designed by Pucci were for the Reed College skiing team. His designs came to wider attention in 1947, when he was on leave in Zermatt, Switzerland. Skiwear that he had designed for a female friend was photographed by Toni Frissell, a photographer working for Harper's Bazaar. Frissell's editor asked Pucci to design skiwear for a story on European Winter Fashion, which ran in the winter 1948 issue of the Bazaar.

Pucci was the first person to design a one-piece ski suit. Although there had been some experiments with stretch fabrics in Europe before the war, Pucci's sleek designs caused a sensation, and he received several offers from American manufacturers to produce them. Instead, he left the Air Force and set up an haute couture house in the fashionable resort of Canzone del Mare on the Isle of Capri.

Initially, he used his knowledge of stretch fabrics to produce a swimwear line in 1949, but he soon moved onto other items such as brightly coloured, boldly patterned silk scarves. Stanley Marcus of Neiman Marcus encouraged him to use the designs in blouses and then a popular line of wrinkle-free printed silk dresses. In 1951 Giovanni Battista Giorgini invited journalists and buyers from around the world to a Made in Italy fashion show in Florence featuring Emilio Schuberth, Sorelle Fontana, Simonetta Colonna di Cesarò, Roberto Capucci, Alberto Fabiani, Jole Veneziani, and Pucci.
