The 1955-56 Serie A was the fifty-fourth edition of the Italian Football Championship. It was the twenty-third Italian Football Championship branded Serie A, since Serie A was launched in 1929. This was the thirtieth season from which the Italian Football Champions adorned their team jerseys in the subsequent season with a Scudetto. Fiorentina were champions for the first time in their history. This was thus their second scudetto since the scudetto started being awarded in 1924, and their first win contested as Serie A.
