The Goya Award for Best Original Song (Spanish: Premio Goya a la mejor canción original) is one of the Goya Awards, Spain's principal national film awards.

The award was first presented at the fifteenth edition in 2001 with the first winner being the song "Fugitivas", written by Manuel Malou, Natboccara and JJ Chaleco for Miguel Hermoso's film of the same name.

Spanish singer Leiva is the only person who has won the award more than once with two wins: in 2017 for "La llamada" from the musical Holy Camp!

Directors David Trueba, Rodrigo Cortés, Emilio Aragón, Paula Ortiz, Pablo Berger, Paco León and Paul Urkijo, all have been nominated as writers of co-writers for songs from their films, with Berger winning the award in 2012 for the song "No te puedo encontrar" from his film Blancanieves.

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.
