In ancient Greek religion and Greek mythology, Minthe is an Underworld Naiad nymph associated with the river Cocytus. She was beloved by Hades, the King of the Underworld, and became his mistress. But she was transformed into a mint plant by either his wife Persephone or her mother Demeter. The plant was also called by some as hedyosmos, which means "sweet-smelling".

A nymph is a minor female nature deity in ancient Greek folklore. Distinct from other Greek goddesses, nymphs are generally regarded as personifications of nature, are typically tied to a specific place or landform, and are usually depicted as maidens. They were immortal like other goddesses, except for the Hamadryads, whose lives were bound to a specific tree.
