The 1983 Italian Grand Prix was a Formula One motor race held at Monza on 11 September 1983.

The 52-lap race was won by Nelson Piquet, driving a Brabham-BMW, with René Arnoux second in a Ferrari and Eddie Cheever third in a Renault.

After completing a pit stop, Niki Lauda's McLaren-TAG stalled in front of the Brabham garage.

The Brabham crew, who were preparing for Nelson Piquet's stop, were joined by team owner and FOCA chief executive Bernie Ecclestone in giving Lauda a push start, to get him back into the race and to clear the area for Piquet.

Another incident occurred at the end of the race, when the tifosi ran onto the track to celebrate Arnoux's second place with the cars still going round.
