Latin Grammy Award for Best Singer-Songwriter Song

The Latin Grammy Award for Best Singer-Songwriter Song is an award presented annually by the Latin Academy of Recording Arts & Sciences at the Latin Grammy Awards.

The description of the category at the 2023 Latin Grammy Awards states that it is "singles or tracks from a current singer-songwriter album currently competing in the singer-songwriter album category" and that, in order to be eligible, a song "must contain at least 51% of the lyrics in Spanish, Portuguese or any native regional dialect". The song must be new and has to be composed and performed entirely by the singer-songwriter.

The category will be first awarded at the 24th Annual Latin Grammy Awards in 2023, alongside two other categories (Songwriter of the Year and Best Portuguese-Language Urban Performance) that were also introduced said year.
