Formula Junior is an open wheel formula racing class first adopted in October 1958 by the CSI. The class was intended to provide an entry level class where drivers could use inexpensive mechanical components from ordinary automobiles. The idea to form the new class came from Count Giovanni "Johnny" Lurani who saw the need of a class for single-seater racing cars where younger drivers could take their first steps. It is often speculated that this class was founded as a reaction to Italy's lack of success in the 500cc Formula Three, and although Italian marques dominated the first year of the formula, they were soon overtaken by British constructors.

Giovanni “Johnny” Lurani Cernuschi, VIII Count of Calvenzano was an Italian automobile engineer, racing car driver and journalist.
