The actress will be given the Britannia Award for British Artist of the Year at the ceremony on November 30 at the Beverly Hilton Hotel.
Nigel Lythgoe, the Chairman of BAFTA Los Angeles, said: 'Helena Bonham Carter is an actress of immense versatility, and her range across movies of all genres is at once remarkable and fearless.
'She unwaveringly maintains her integrity and, through her choice of roles, continually challenges both herself and her audiences' perception of her.'
