1909 Italian Football Championship

The 1909 Italian Football Championship was the 12th Italian Football Championship and the sixth since re-branding to Prima Categoria. Again the contest was made up of clubs exclusively from the 3 Northern Italian regions of Liguria, Lombardy and Piedmont. In the second of two highly political consecutive seasons of Italian football, two championships of Prima Categoria were played; one exclusively with Italian players and a competition (deemed secondary the season before), that included non-Italians. However, political manoeuvring by the clubs with foreign players meant that this season, the competition with foreign players was ultimately deemed more important. Hence the 1909 Italian Football Championship is officially recognised as won by Pro Vercelli who won the competition that included non-Italian players. That is despite that the previous season they are also recognised as champions, having won the competition that year that featured only Italian players.

The number of entrants in what is now viewed as the main contest doubled from the previous year to eight.
