A dying god, or departure of the gods, is a motif in mythology in which one or more gods (of a pantheon) die, are destroyed, or depart permanently from their place on Earth to elsewhere.
Frequently cited examples of dying gods are Baldr in Norse mythology. A special subcategory is the death of an entire pantheon, the most notable example being Ragnarök in Norse mythology, or Cronus and the Titans from Greek mythology, with other examples from Ireland, India, Hawaii and Tahiti. Examples of the disappearing god in Hattian and Hittite mythology include Telipinu and Hannahanna.
