A broken heart (or heartbreak) is a common metaphor used to describe the intense emotional pain or suffering one feels after losing a loved one, whether through death, divorce, breakup, physical separation, or romantic rejection.

Heartbreak is usually associated with losing a family member or spouse, though losing a parent, child, pet, lover or close friend can all "break one's heart", and it is frequently experienced during grief and bereavement. The phrase refers to the physical pain one may feel in the chest as a result of the loss, although it also by extension includes the emotional trauma of loss even where it is not experienced as somatic pain. Although "heartbreak" ordinarily does not imply any physical defect in the heart, there is a condition known as "Takotsubo cardiomyopathy" (broken heart syndrome), where a traumatising incident triggers the brain to distribute chemicals that weaken heart tissue.

For many people having a broken heart is something that may not be recognized at first, as it takes time for an emotional or physical loss to be fully acknowledged. As Jeffrey Moussaieff Masson states:
