Gianni Mazzocchi was an Italian magazine editor-proprietor, originally from Marche, with an unusual degree of energy and entrepreneurial flair; he moved north to Milan and became a leading print-media magnate. He founded more than fifteen national magazines including several, such as Il Mondo, L'Europeo, and Quattroruote, that continued to feature prominently on the nation's news stands long after his death.

Il Mondo was a weekly political, cultural and economic magazine founded by Gianni Mazzocchi and directed by Mario Pannunzio. It existed between 1949 and 2014.
