Vincenzo Zucconelli (Italian pronunciation: [vinˈtʃɛntso ddzukkoˈnɛlli], born 3 June 1931) was a road racing cyclist from Italy who won the silver medal in the men's team road race, alongside Dino Bruni and Gianni Ghidini. Italy's fourth rider Bruno Monti also crossed the line, but did not receive a medal because just the first three counted for the final classification. He was a professional rider from 1954 to 1959.
