The FISA–FOCA war was a political battle contested throughout the early 1980s by two now defunct representative organizations in Formula One motor racing, the Fédération Internationale du Sport Automobile (FISA) and the Formula One Constructors Association (FOCA). The battle boiled during the late 1970s and early 1980s and came to a head when the racing teams affiliated with FOCA, an equivalent to a racing team union, boycotted the 1982 San Marino Grand Prix.
