Project Four Racing was a British Formula Two and Formula Three team. The team was founded in 1976 by former Brabham mechanic Ron Dennis. At the end of 1980, the team merged with the McLaren Formula One team.

The team name lived on in the designation of the McLaren F1 race cars from to the  season, all McLarens, starting with the John Barnard designed McLaren MP4/1, had carried the "MP4" name, with MP4 standing for "Marlboro Project 4" and later "McLaren Project 4". The road car McLaren MP4-12C also carried the prefix until it was dropped for the 2012 model year.

Stefan Johansson won the 1980 British Formula Three Championship driving for Project Four Racing.

BMW M1 Procar Championship
For the BMW M1 Procar Championship, all cars were built to identical standards, although their origins varied. BS Fabrications constructed five cars for the BMW factory team, while cars for other competitors were constructed by Project Four Racing or the Italian constructor Osella. The racing cars, designed to meet Group 4 technical regulations, shared only some basics from the M1 road cars.

In 1979, Procar constructor Project Four entered a car for Niki Lauda when he was not in the factory entries. Lauda won 3 races for P4, and the series, before retiring from F1 racing in late September. In 1980, Hans-Joachim Stuck won two events for P4, finishing 3rd overall.
