Serie A is Italy's premier professional football league, officially established in the 1929–30 season, evolving from the Italian Football Championship which had been played since 1898. The Italian Football Federation (FIGC) officially recognizes these earlier championships as equal to modern Serie A titles, with winning teams proudly displaying the "scudetto" emblem on their kits. Renowned for its tactical discipline and defensive rigor, Serie A consistently ranks among the world's strongest leagues, currently holding the second position in UEFA's coefficient as of 2024–25.

It is home to iconic clubs like Juventus (Italy's most decorated), Inter Milan (who achieved a continental treble in 2009–10), and AC Milan (joint-third for most UEFA titles), forming part of the famous "seven sisters" of Italian football. These clubs have not only dominated domestically but have also achieved significant international success, attracting top global talent and producing numerous Ballon d'Or winners throughout history.
