The GP2 Series has been renamed the FIA Formula 2 Championship as part of the FIA's single seater restructure.
Ratified at this week's World Motor Sport Council meeting, the move completes the new look FIA single-seater pyramid.
The FIA Formula 2 name was previously used from 1967-1984 before being revived by Jonathan Palmer's F2 series from 2009-2012.
“With FIA Formula 2, we now have everything we need to craft a clear and logical path for single seater drivers from grassroots for Formula One,” said FIA Single-Seater Commission President Stefano Domenicali.
“As they progress from karting, we have FIA Formula 4 at national level in countries all over the world, and from there the FIA Formula 3 European Championship is a fantastic proving ground before drivers take on the challenge of competing on the world stage.
The FIA Formula 2 Championship will begin at Bahrain from April 14-16.
