The 1909–10 Prima Categoria season was won by Internazionale.

Regulation

Following the creation of the Italy national football team, the Italian Football Federation revamped its championship. The round robin was introduced in Italy this season. Registration was free and only subject to a quality committee. The eight clubs of the last years were joined by Ausonia, a Milanese car factory‘s club which paid the enrolment tax to try the experience of a national football championship.

Championship tie-breaker

Played in Vercelli on April 24 Pro Vercelli had previously planned to join two football exhibitions on April 17 and 24, and asked FIGC to postpone the tie-breaker to May 1; however, Inter was against playing the game on May 1 due to its own planned exhibitions. FIGC granted the first postponement, but since Pro Vercelli no longer took part in the April 17 exhibition, the second postponement was withdrawn and the tie-breaker scheduled on 24 April. Pro Vercelli fielded its fourth squad (15-year-old boys) in protest; after that, FIGC imposed to the club a penalty for insubordination and unsportsmanlike conduct.
