1969 Formula One season

The 1969 Formula One season included the 20th FIA Formula One World Championship season, which commenced on 1 March 1969, and ended on 19 October after eleven races.

Matra withdrew their works team from the 1969 championship and focused on their partnership with Ken Tyrrell. Stewart won the 1969 title easily with the new Matra MS80, which corrected most of the weaknesses of the MS10. Stewart's title was the first won by a French chassis, and the only one won by a chassis built in France. It was a spectacular achievement from a constructor that had only entered Formula One the previous year. It would also be the only time a constructor won in Formula One without fielding a works team.

Jacky Ickx had a strong second half to the season for Brabham, winning in Germany and Canada, after Jack Brabham was sidelined by a testing accident. Ickx finished second in the Drivers' Championship, with 37 points to Jackie Stewart's 63.

The season was the first to see the use of add-on aerodynamic devices. After several incidents in which wings, struts, or the suspension (to which they were attached) collapsed, wings were banned from Monaco 1969. They were reintroduced later in the season but were to be restricted in size and height, and attached directly to the chassis in a fixed position.

1969 also saw a brief resurgence of interest in four wheel drive following a number of wet races the previous year. Four such cars were entered for the British Grand Prix, and Johnny Servoz-Gavin became the one and only driver to score a point with a 4WD, finishing sixth with the Matra MS84 at the Canadian Grand Prix. At the same race, Al Pease made history by being the only driver disqualified from a World Championship event for being too slow. Wide tyres and downforce quickly proved to be superior means of increasing grip, and the technology was largely abandoned, although Lotus continued to experiment with the idea for a few more years. Bruce McLaren described the handling of his M9 as being like trying to sign an autograph while someone was jogging his elbow; Cosworth discovered that their car handled better the more drive went to the rear wheels.
