"The Only Heartbreaker" is a song by American singer Mitski, released on November 9, 2021[1] as the second single from her sixth studio album, Laurel Hell.

[2][3][4] Mitski said that "The Only Heartbreaker" is about "the person always messing up in the relationship, the designated Bad Guy who gets the blame.

[6] Sue Park of Pitchfork wrote that the song "veers away from subdued indie rock and into full-fledged frenzy, recalling the exuberant synth-pop of the 1980s as Mitski implicates herself in the inevitable unraveling of a toxic relationship".

[7] A music video for "The Only Heartbreaker" was released on the same day as the single, directed by Maegan Houang and Jeff Desom.

[8] According to Uproxx, the video shows Mitski dancing through a forest and reeling in despair as she realizes that she's unintentionally killing everything she comes into contact with.
