The 1930-31 Serie A was the thirty-first edition of the Italian Football Championship and the second since 1929 re-branding to create Serie A. It was the eighth season from which the Italian Football Champions adorned their team jerseys in the subsequent season with a Scudetto. Juventus won for the first of five successive wins, and for the third time in their history. This was their second scudetto since the scudetto started being awarded in 1924 and their first win contested as Serie A.
Casale and Legnano had been promoted from Serie B.
