Formula One Constructors' Association

The Formula One Constructors' Association (FOCA) is an organization of the chassis builders (constructors) who design and build the cars that race in the FIA Formula One World Championship. It was originally established by Bernie Ecclestone, Frank Williams, Colin Chapman, Teddy Mayer, Ken Tyrrell, and Max Mosley (originally a co-founder of March Engineering) to represent the interests of their privately owned teams. Ecclestone became the organisation's chief executive in 1978, with Mosley taking on the role of legal advisor.

In the early 1980s, the organization fell out with the sport's governing body – the FISA. The eventual resolution of this conflict saw Ecclestone take a more significant role in the running of the sport with the formation of FOA (Formula One Administration).

Following the disqualification of Nelson Piquet and Keke Rosberg from the 1982 Brazilian Grand Prix, numerous FOCA-aligned teams including McLaren, Williams and Brabham boycotted the San Marino Grand Prix. Four FOCA-aligned teams - Tyrrell, Osella, ATS and Toleman - broke their stated boycott and started the race anyway.
