"Hearts on Fire" is a song by Australian electronic music band Cut Copy, released in 2007 as the lead single from their second studio album, In Ghost Colours (2008). A re-edited version of the song, produced by Tim Goldsworthy, was released on 5 July 2008 and served as the album version. Pitchfork Media named "Hearts on Fire" the seventh best track of 2008.

The music video, directed by Nagi Noda and shot on location in Japan, portrays a lovelorn frontman Dan Whitford suffering from a breakup. He is constantly followed by a rainy cloud hanging over his head, which represents his sadness. After time goes by (demonstrated by the growth of his dog), he finally lets go of the pain and continues his life without the rain following him, until the very end of the video during which he runs into his ex-girlfriend, causing the rain to resume.
