The 1956 Formula One season was the tenth season of FIA's Formula One motor racing. It featured the seventh World Championship of Drivers. The championship series commenced on 22 January and ended on 2 September after eight races. Juan Manuel Fangio won his third consecutive title, the fourth of his career.

Fangio joined Ferrari after Mercedes-Benz, with whom he had won the 1954 and 1955 titles, withdrew from the sport. Ferrari acquired the folded Lancia team's D50 cars and put together a strong team containing Fangio, Eugenio Castellotti, Luigi Musso and Peter Collins. Fangio won the opening race after commandeering Musso's car after his own broke down. Collins and Fangio's teammate at Mercedes, Stirling Moss – now driving for Maserati provided the biggest challenge to his title defence, each winning two races.

Going into the final race of the season, Fangio had an eight-point lead over Collins and the consistent Jean Behra, driving for Maserati. The only way he could lose the title would be to score no points, with Collins winning and setting the fastest lap. Fangio retired, and with Musso unwilling to share his car with Fangio, Collins had a great chance of winning his first title. In a remarkable act of sportsmanship, Collins instead chose to hand his car over to Fangio to allow the Argentine to finish second in the race and win his third title in a row.
