Goya Award for Best Original Score

The Goya Award for Best Original Score (Mejor música original) is one of the Goya Awards, Spain's principal national film awards. The category has been presented ever since the first edition of the Goya Awards. Spanish folk band Milladoiro was the first winner of the award for their work in the film Half of Heaven (1986). Composer Alberto Iglesias holds the record of most wins and nominations for this award, winning eleven times out of seventeen nominations.

For the 39th ceremony, the Academy of Cinematographic Arts and Sciences of Spain introduced a modification consisting of the requirement of a declaration signed by the producers accrediting the non-submission of AI-generated compositions. In the list below the winner of the award for each year is shown first, followed by the other nominees.
