After a 50 year absence, Ferrari will return to Le Mans in the world endurance series' top category in 2023.
Toyota, Peugeot, Porsche and Audi have also committed to the new Hypercar category, which according to the FIA was created to be "equally appealing to both global automotive brands as well as specialist firms building road-going supercars".
"I believe in the concept of road relevant Hypercars competing in the WEC and at the 24 Hours of Le Mans," said FIA president and former Ferrari boss Jean Todt.
"I'm looking forward to seeing this legendary brand taking on this ambitious project."
Ferrari last won Le Mans outright in 1965.
Meanwhile, Italian media report that Ferrari's Formula 1 car for 2021 will feature two tones of red - lighter at the bottom and darker towards the top.
It is also believed that Mattia Binotto will not attend many races this season, with the Maranello team to instead be headed at the circuits by Laurent Mekies.
