The 2020 Italian Grand Prix was a Formula One motor race that was held on 6 September 2020 at the Autodromo Nazionale di Monza in Monza. The race was the eighth round in the 2020 Formula One World Championship.

The race was won by Pierre Gasly of AlphaTauri-Honda, who took his first Formula One win and became the first French Formula One driver to win a race since Olivier Panis won the 1996 Monaco Grand Prix. Gasly started the race in tenth, but gained positions due to a well-timed pit-stop prior to a safety car, sent to retrieve the broken car of Kevin Magnussen. Lewis Hamilton, who led the race until this point, was given a penalty for entering the pit lane when it was closed, passing the lead to Gasly, who defended from McLaren's Carlos Sainz in the closing stages of the race. Racing Point's Lance Stroll completed the podium. It turned out to be the organisation's only Grand Prix win under the Scuderia AlphaTauri name.

This was the first race since the 2012 Hungarian Grand Prix to not have a Red Bull, Mercedes, or Ferrari driver on the podium, the first of those podiums to feature three different teams since the 2012 Canadian Grand Prix and the first to feature a red flag since the 2017 Azerbaijan Grand Prix. It was also the first race not to be won by a driver from Red Bull, Mercedes, or Ferrari since the 2013 Australian Grand Prix. Lance Stroll also scored his first podium since the 2017 Azerbaijan Grand Prix. It was the first instance of there being two standing starts since the 2001 Belgian Grand Prix, following a 2018 change in the regulations to allow for standing restarts after a red flag. This race was the last for both Claire Williams and Frank Williams, as they stepped down from their positions at Williams Racing.
