Ciarán

Ciarán is a masculine given name of Irish origin. It derives from the Gaelic Ciarán, a diminutive of ciar meaning "dark" or "black," commonly interpreted as "little dark one" or "little dark-haired one." The name is widespread in Ireland and among the Irish diaspora, with several Anglicized spellings such as Kieran, Kiernan, and Keiran.

Etymology and saints: The name predates modern usage and is associated with early Irish Christianity. The most famous bearers are Saint Ciarán of Clonmacnoise, founder of Clonmacnoise monastery in the 6th century, and Saint Ciarán of Saighir (5th century). The Feast of Saint Ciarán of Clonmacnoise is celebrated on 9 September in the Catholic tradition.

Usage and variations: The form Kieran is especially common in English-speaking countries; other spellings include Kiernan, Keiran, and Keiran. While Ciarán remains the standard Irish spelling, the name is used across Ireland and in the global Irish diaspora.

Notable people: Beyond the saints, modern bearers include the Irish actor Ciarán Hinds (born 1953), known for work on stage and screen. The name appears across fields in Ireland and among communities of Irish heritage worldwide.
