The Italian Grand Prix () is the fifth oldest national Grand Prix (after the French Grand Prix, the American Grand Prize, the Spanish Grand Prix and the Russian Grand Prix), having been held since 1921. In 2013 it became the most held Grand Prix (the 2019 edition was the 89th). It is one of the two Grands Prix (along with the British) which has run as an event of the Formula One World Championship Grands Prix every season, continuously since the championship was introduced in 1950. Every Formula One Italian Grand Prix in the World Championship era has been held at Monza except in 1980, when it was held at Imola.
