Butterfly (Marina song)

"Butterfly" is a song by Welsh singer and songwriter Marina from her sixth studio album, Princess of Power (2025). It was independently released as the lead single, alongside an accompanying music video on 21 February 2025. This marked her first self-released song since both of her extended plays Mermaid vs Sailor (2007) and Froot Acoustic (2015).

Her first single release in nearly four years, Marina wrote and recorded the alt-pop and chamber pop song, and co-produced the record with American songwriter CJ Baran. Music critics highlighted the lyricism for "Butterfly" representing the insect of the same name through its life cycle, personal growth of an individual, and spiritual rebirth. The music video was directed by Aerin Moreno, where it depicts Marina dancing and singing through several liminal spaces.

Marina promoted the song with a live performance at music festival Coachella 2025. Commercially, the song did not make an impact but appeared on the top 50 in the United Kingdom for downloads and sales, and the top 20 in New Zealand for its fast streams and airplay.
