The 1964 Formula One season was the 18th season of FIA Formula One motor racing. It included the 1964 World Championship of Drivers, won by John Surtees; and the 1964 International Cup for F1 Manufacturers, won by Ferrari – both of which were contested concurrently over a series which commenced on 10 May and ended on 25 October after ten races.

The World Championship of Drivers, fiercely contested by Jim Clark, John Surtees and Graham Hill, was decided at the Mexican Grand Prix when Hill was delayed after a collision with Lorenzo Bandini's Ferrari. Clark was forced to stop with an oil leak on the last lap, and Ferrari signalled Bandini to let Surtees through into the second place which gave him the championship by one point from Hill. A Ferrari 158 car officially entered by the American privateer team NART sealed the win of the championship with Surtees, as the works team competed the last two races (the United States Grand Prix and Mexican Grand Prix) in cars painted white and blue. This was done as a protest concerning arguments between Ferrari and the Italian motorsport body ACI regarding the homologation of a new mid-engined Ferrari Le Mans race car. Ferrari won the International Cup for F1 Manufacturers. Honda made a low-key debut in Grand Prix racing with the American driver Ronnie Bucknum, and Maurice Trintignant retired at the age of 46 after one of the longest world championship careers. He was the last active driver to have competed in the first World Championship season in 1950.

Dutchman Carel Godin de Beaufort died during practice for the German Grand Prix at the Nürburgring, driving a privately entered Porsche 718.
