Italian football champions

The first Italian Football Championship was a single day knock-out competition won by Genoa CFC. Numerous expansions and re-formats of what are recognised as official Italian Football Championship included re-brands to Prima Categoria from 1909–10 season, to Prima Divisione from 1921–22 season, and to Divisione Nazionale from 1926–27 season. Since the re-brand to Serie A from 1929, Serie A has been used as the Italian Football Championship for all but one season competitive Italian Football has been played. A regional based competition branded Divisione Nazionale was resurrected for the first season of football immediately after World War II.
