The 2017 Monza GP3 Series round was the sixth round of the 2017 GP3 Series.

It was held on 2 and 3 September 2017 at Autodromo Nazionale Monza in Monza, Italy.

The race supported the 2017 Italian Grand Prix.

Heavy rain forced the rescheduling of race 1 to the original spot of race 2, leaving no time for race 2 to take place.
