The 1965 Italian Grand Prix (formally the XXXVI Gran Premio d'Italia) was a Formula One motor race held at Monza on 12 September 1965.

The race was won by Jackie Stewart who took his first Grand Prix victory, whilst driving for the BRM team.

His fuel-pump failure with a handful of laps to go, and also the preceding retirement of Ferrari driver John Surtees, ensured that Dan Gurney of the Brabham-Climax team picked up the final position on the podium.

Jim Clark duelled for the lead through the first two-thirds of the race with Graham Hill, Jackie Stewart and John Surtees (who dropped out with clutch problems), until lap 64 when his fuel pump failed.

However, on the approach to the Parabolica on the last time, Hill moved over too far and bounced across the grass, struggling to maintain grip on the mud and gravel.
