In Greek mythology, Oizys (Ancient Greek: Ὀϊζύς, "misery"), or Oezys (Οἰζύς), is the personification of pain or distress. In Hesiod's Theogony she is one of the fatherless offspring of Nyx (Night). Roman authors name her Latin counterpart Miseria among the children of Nox and Erebus. She has no distinct mythology of her own beyond that genealogical notice.

I.Child of Night
Hesiod's Theogony lists Oizys among the brood Nyx produces without a father — alongside Moros, Ker, Thanatos, Hypnos, the Oneiroi, Momus, and other dark abstractions. She personifies pain and distress rather than starring in an independent saga.
Cicero and Hyginus record Miseria (Misery) as offspring of Nox and Erebus, the Roman pairing that answers Hesiod's Nyx-born Oizys.
II.Reception
Because she lacks cult myth beyond the Theogony catalogue, later literature treats Oizys as a genealogical and allegorical figure — misery personified — rather than as an actor in epic narrative.
