The Serie B 1933–34 was the fifth tournament of this competition played in Italy since its creation. This championship was organized with two groups and a final round to determine the promoted team.

Teams Viareggio, Perugia and Foggia had been promoted from Prima Divisione, while Bari and Pro Patria had been relegated from Serie A. Atalanta and Pistoiese had been re-elected by the Higher Directory to expand the league.

More, during the summer the FIGC decided to abolish with immediate effect the round robin as too expensive, and Catanzaro, Seregno, SPAL, Pavia, Vicenza and Derthona were invited to join.

As the fascist authorities forbade a natural North-South division, a strange West-East partition was established.
