The 2007 Formula One espionage controversy, also known as Spygate and Stepneygate, was a set of accusations among Formula One racing teams that confidential technical information had been passed between them. It involved the McLaren, Ferrari and Renault F1 teams.

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.
