Origin: Irish

Meaning: Ancient

Kienan is a masculine name of Irish origin, meaning “ancient.” This compelling appellation is a form of Keenan, the anglicized surname Ó Cianáin, from Cían. In Irish mythology, Cían was the physician of the Tuatha Dé Danann and the father of the warrior king Lugh. A name that sings off the tongue and perks up the ears, Kienan has a lightness to it despite its timeless essence. Not only does Kienan nod to baby’s ancestry, but it embodies Ireland’s ancient mysticism, making it an obvious choice.
