1945–46 Italian Football Championship
The 1945–46 Italian Football Championship officially known as 1945–46 Divisione Nazionale, was the forty-fourth edition of the Italian Football Championship. It was the twenty-first season from which the Italian Football Champions adorned their team jerseys in the subsequent season with a Scudetto. 1945-46 was the first Italian Football Championship held after the ravages of World War II. Hence the authorities resurrected a one season return to the Divisione Nazionale two region set up, instead of the nationwide Serie A brand introduced in 1929.
Torino FC were champions for the third time in their history. This was their third scudetto since the scudetto started being awarded in 1924 and their second 'non-Serie A' style win. This was their second of five consecutive Italian Football Championship wins, punctuated by a two-year break due to World War II.
