'''FIA Formula 3''', commonly referred to simply as '''F3''', is the third tier of open-wheel racing sanctioned by the FIA. Formula 3 is designed to be a step-up from [[Formula 4]] that begins to prepare a driver for racing at higher echelons of motorsport, with the main differences being an increase in downforce and engine power, along with an increased emphasis on setting up the car and driver feedback.

The first F3 series was the short-lived [[FIA Formula 3 Eurasian Championship|Eurasian championship]], hosting its inaugural season in [[2018 FIA Formula 3 Eurasian Championship season|2018]]. Eurasian F3 would be joined in 2019 by the arrival of the [[FIA Formula 3 Americas Championship|Americas championship]] before the Eurasian series would be split into [[FIA Formula 3 European Championship|European]] and [[FIA Formula 3 Asian Championship|Asian]] championships, bringing the total number of F3 series to three.
