The term true lover's knot, also called true love knot, is used for many distinct knots. The association of knots with the symbolism of love, friendship and affection dates back to antiquity. Because of this, no single knot can be labeled the true "true love knot".

"Barbara Allen" is a traditional folk song that is popular throughout the English-speaking world and beyond. It tells of how the eponymous character denies a dying man's love, then dies of grief soon after his untimely death.
