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.
