Osvaldo Bagnoli (born 3 July 1935 in Milan) is a former Italian football coach.
During his long and illustrious career, he is best remembered for being the coach which led the underdogs Verona to its first (and so far the only) Serie A title in the 1984–85 season.
He has also coached a number of other Serie A teams, including Genoa and Inter.
In the 1990–91 season, Bagnoli took Genoa to fourth in the standings in his first year in charge. It was the team's best finishing position for more than 50 years.
