The American singer has been chosen along with four others - including Russian punk band Pussy Riot and the late writer Christopher Hitchens - to receive the biennial LennonOno Grant For Peace.
Gaga is expected to accept the award and a donation from Lennon's widow, Yoko Ono, in Reykjavik, Iceland, on Oct. 9 - the birthday of John Lennon and his son, Sean.
Ono said in a statement Friday that while Gaga is "one of the biggest living artists of our time" she is also an activist whose album Born This Way altered "the mental map of the world."
