The Formula 3000 International Championship was a motor racing series created by the Fdration Internationale de l'Automobile (FIA) in 1985 to become the final preparatory step for drivers hoping to enter Formula One. Formula Two had become too expensive, and was dominated by works-run cars with factory engines; the hope was that Formula 3000 would offer quicker, cheaper, more open racing. The series began as an open specification, then tyres were standardized from 1986 onwards, followed by engines and chassis in 1996. The series ran annually until 2004, and was replaced in 2005 by the GP2 Series.

The series was staged as the Formula 3000 European Championship in 1985, as the Formula 3000 Intercontinental Championship in 1986 and 1987 and then as the Formula 3000 International Championship from 1988 to 2004.

Marco Campos (24 February 1976 – 15 October 1995) was a Brazilian racing driver. He died in an accident in a Formula 3000 race at the Circuit de Nevers Magny-Cours, making him the only driver to be fatally injured in the International Formula 3000 series. His death would be the last at the top level of feeder series racing until the fatal accident of Anthoine Hubert in Formula 2 in 2019.
