Amaia Romero Arbizu is a Spanish singer. She is the winner of the ninth series of Operación Triunfo. Her growth through the competition and her consistent performances earned her the title of "Amaia de España" by the Spanish public (a title that was similarly given to the winner of the first series, Rosa López).

She represented Spain together with fellow finalist Alfred García at the Eurovision Song Contest 2018 in Lisbon with the song Tu canción, finishing in 23rd place.
