The Ferrari 643 was a Formula One car designed by Steve Nichols and Jean-Claude Migeot and was built by Scuderia Ferrari for use in the 1991 Formula One season. Introduced at the French Grand Prix after being developed in May, the car initially demonstrated strong potential to compete at the front of the grid. Alain Prost qualified on the front row and briefly led the race before being overtaken by Nigel Mansell in the Renault-powered Williams FW14. Nevertheless, a second-place finish in its debut outing was regarded as an encouraging start. Ultimately, the car would help the team finish third in the 1991 Constructors' Championship.
