The 1908 Italian Football Championship was the 11th edition of the Italian Football Championship and the fifth 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 first 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 that included non-Italians. The number of entrants in what was now the main contest went down from six the previous year to four. Two Piedmont teams played off to decide who played in the 3 club round robin final stage. Pro Vercelli won the Italian football championship for the 1st time.

Two championships were competed for that year:

Only Pro Vercelli's title is officially recognized by the Italian Football Federation. The Federal Championship won by Juventus was later annulled by FIGC, due to the boycott made by the "spurious international teams" (the clubs composed mostly of foreign players).

Andrea Doria was the only registered team.

US Milanese was the only registered team.
