The Circuit of Wales track replaced Silverstone as the new host of the Grand Prix last month, but the track will not be ready until the 2016 season.
Carmelo Ezpeleta, CEO of MotoGP promoter Dorna said: "The Circuit of Wales has worked very quickly to secure the best deal for British race fans and we believe Donington Park will deliver a fantastic race in 2015.
Donington Park has had a long history of holding the Grand Prix, as it held the race over a 22 year period from 1987 to 2009.
Public opinion seems to be glad that the Grand Prix is returning to the Leicestershire circuit when they heard that the race could be returning there in 2015.
“It was no surprise that Donington’s name was thrown into the ring when it became clear that a new venue for the 2015 competition was being sought – and the enormous fan enthusiasm for a possible return, as shown in several public opinion polls, really brought home to us how well-loved our circuit is by so many MotoGP fans." said Donington MD Chris Tate to Bike sports News
Silverstone was offered to keep the race for another year, but they could not agree a fair economic contract so the race had to find a new home for 2015.
The Circuit of Wales track should be ready to host the Grand Prix in 2016 with their contract set to run out in 2020.
