The 1951–52 Serie A season was won by Juventus.

Six out of the twenty clubs came from Lombardy, a record for a single region of Italy.

FIGC decided to restore the original 18-clubs format, so a special relegation would have been necessary.

The 3 last-placed teams in Serie A were guaranteed relegation.

Lucchese was relegated and Triestina qualified for the playoff game against Brescia, Serie B's 2nd-placed team.
