"Heartbreaker" is a song co-written and recorded by Canadian country music artist Jess Moskaluke.

She added that when writing the song with Corey Crowder and Emily Shackelton, they "tried to embody the sense of longing that comes along with falling for someone emotionally broken from a previous relationship".
