Williams Grand Prix Engineering Limited, currently racing in Formula One as Williams Racing, is a British Formula One team and constructor. It was founded by Sir Frank Williams (1942–2021) and Sir Patrick Head. The team was formed in 1977 after Frank Williams's earlier unsuccessful F1 operation: Frank Williams Racing Cars.

Formula One, commonly known as Formula 1 or F1, is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been one of the world's premier forms of racing since its inaugural running in 1950. The word formula in the name refers to the set of rules all participants' cars must follow. A Formula One season consists of a series of races, known as Grands Prix. Grands Prix take place in multiple countries and continents on either purpose-built circuits or closed public roads.
