The 1985 International Formula 3000 Championship was the inaugural season of the Formula 3000 category. The International Formula 3000 Championship replaced Formula Two as the official feeder series to Formula One. It was scheduled over 12 rounds and contested over 11 rounds. 14 different teams tried their luck with 33 different drivers and 7 different chassis. The series was won by the German Christian Danner driving for BS Automotive.
Danner had the dubious honour of being the first in a long line of Formula 3000 champions who would fail to make an impact on Formula One, despite the championship being seen as the highest level FIA single seater championship behind Grand Prix racing. Only future champions Jean Alesi, Olivier Panis and Juan Pablo Montoya would actually go on to win a Formula One Grand Prix.
