Origin:Irish
Meaning:Black; Little dark one
Kieran is a boy’s name and the Anglicized spelling of the Irish title Ciarán (pronounced keer-awn). Deriving from the Irish element ciar, Kieran means “black" or "little dark one," so it's a fitting choice for a tiny tot with dark hair or a mischievous streak that's evident from the very start! American actor Kieran Culkin is one well-known bearer of this title, so it has traveled a long way from its Irish beginnings. Kieran's ending sound can be pronounced in many different ways, but there are two main options, as The Bump community member, nittanyllama, explains, "I would pronounce it Keer-un or Keer-en."
