It was the penultimate round of the 2020 FIA Formula 3 Championship, and ran in support of the 2020 Italian Grand Prix.

With Frederik Vesti's win and Oscar Piastri finishing in third in the first race, Prema Racing prematurely secured the teams' championship back-to-back with three races to spare.

Sophia Flörsch returned to drive for Campos Racing, with Andreas Estner, her replacement in Spa, returning to the Euroformula Open Championship.

The Qualifying session took place on 4 September 2020, with Théo Pourchaire setting the fastest laptime of the session.

However, him, Smolyar, Chovet, Zendeli, Caldwell, Fernández, Beckmann, Vesti and championship leader Oscar Piastri were all penalized for blocking the track in Qualifying, therefore allowing Liam Lawson, who had initially set the fourth-best laptime, to inherit pole position.
