Kearnan is Irish in Origin.

Kearnan is an Irish surname-derived given name, a respelling of Kiernan/Kernan, from Gaelic Tighearnán, diminutive of tighearna “lord,” hence “little lord” or “lordly.” The form likely arises from anglicization patterns that replaced the Gaelic Mac Tighearnáin (“son of Tighearnán”) with Kiernan/Kernan and, by extension, Kearnan. Though sometimes associated with Kieran, that name comes from Ciarán (“little dark one”) and is etymologically distinct.

In medieval Ireland, bearers of the related surname - rendered in Irish as Mág Tighearnán or Mac Tighearnáin - were chiefs in Tullyhunco, County Cavan. As a given name, Kearnan follows the modern trend of adopting surnames as first names, with modest use in Ireland, Britain, North America, and Australia since the late 20th century. Variant spellings and cognates include Kiernan, Kernan, Tiernan, Ternan, McKiernan, and McTiernan; the core personal name remains Tighearnán.
