An elder or progenitor race, in science fiction, fantasy, or horror fiction, is an ancient race that not only preceded but helped shape the races that followed, often playing a significant role in the basis of the story. Humanity may have been descended from them, or they may be a different fictional race, such as elves, dwarves, or aliens.^[1] While in some cases, whether they currently exist is unclear, in other instances, members of an elder race still inhabit the world, either openly or in secret. In order to hide their existence, they may make use of a wainscot society, inhabit a parallel universe, only visiting the current one occasionally, or disguise themselves as a fool, deity, magician or trickster.^[1] One such example is in Lord of Light (1967), where highly advanced humans take on the identities of Hindu deities and act as gods to the less advanced colonists.^[2]

Elder races are typically either technologically or spiritually powerful, as well as wise. While sometimes benevolent, assisting younger races, they can also often be amoral, as in H.P. Lovecraft's Cthulhu Mythos, where the Elder Gods are indifferent to humanity's "petty" concerns. They are usually presented as having drifted apart from humanity in the present of the story, sometimes as lost empires whose inhabitants either left their former home for a new one, or were destroyed by a catastrophe and only live on in legend, such as Atlantis. They may appear both as enemies, or as allies against a greater threat.^[2]
