Sadaiya Nayanar or Sadaiyar[note 1] is a 7th century Nayanar saint in the Hindu sect of Shaivism, venerated for being father of the prominent saint Sundarar rather than for individual merit.[1] He and his wife Isaignaniyar are generally counted as sixty-second and sixty-third on the list of the sixty-three Nayanar saints.[2] Sundarar is the only Nayanar with both parents venerated.
