The 1963 Italian Grand Prix was a Formula One motor race held at Monza on 8 September 1963. It was the seventh of ten races in 1963 Formula One season. At this race, Scottish driver Jim Clark clinched the World Championship crown with three races to go, the first time anyone had done so. Lotus-Climax also won the Constructors' Championship.
The organisers had planned to run on the full 10 km circuit but the very bumpy (and in some places ruined) nature of the banked concrete curves provoked much criticism and also caused accidents. Therefore, at the drivers' request, for the next day it was decided to revert to the 5.75 km road layout.
This race was Scuderia Ferrari's 100th start in a World Championship event as a team.
