The 1948-49 Serie A was the forty-seventh edition of the Italian Football Championship. It was the sixteenth Italian Football Championship branded Serie A, since Serie A was launched in 1929. This was the twenty-third season from which the Italian Football Champions adorned their team jerseys in the subsequent season with a Scudetto.
At the request of rival teams Torino were declared champions on 6 May 1949, two days after the Superga air disaster killed their entire first team squad. At the time of the declaration, Torino led the runner-up Internazionale by four points with four matches remaining. Torino's remaining four matches were played by their reserve team, finishing the league five points ahead of the runner up. Torino were thus champions for the sixth time in their history. This was their sixth scudetto since the scudetto started being awarded in 1924 and their fourth win contested as Serie A. This was their last of five consecutive Italian Football Championship wins, punctuated by a two-year break due to World War II.
Novara for Northern Italy, Padova for Central Italy and Palermo for Southern Italy had been promoted from Serie B.
Following the restoration of ordinary Serie B championship, the FIGC decided to come back to two relegations only from Serie A.
