What is the collective name for the three Greek goddesses of fate?

The collective name for the three Greek goddesses of fate was the Moirai.

The Moirai were personifications of destiny, often translated into English as the Fates. Their three members were Clotho, Lachesis, and Atropos. Clotho spun the thread of life, Lachesis measured or allotted the portion assigned to each person, and Atropos cut the thread when life ended. Together, their imagery explains why spinning, measuring, and cutting became enduring symbols of fate.

Greek traditions did not present their genealogy consistently. In Hesiod’s Theogony, the Moirai are first described as daughters of Nyx, or Night. Later in the same poem, they appear as daughters of Zeus and Themis, linking fate with divine law and order. Other traditions connect them with Ananke, the power of necessity. These differences reflect evolving mythic traditions rather than a single canonical family tree.

The Moirai governed the destinies of mortals and, in many accounts, even constrained the gods. They are not the Horae, who represented seasons or orderly time; the Graces, who embodied beauty and charm; or the Erinyes, who pursued wrongdoing and vengeance. Their Roman counterparts were the Parcae.
