Eoin

Eoin is a masculine given name of Irish origin, the Irish form of John. It derives from the Latin Ioannes and has been used in Ireland since medieval times. In Irish orthography the name appears as Eoin or Eóin, and it is typically pronounced roughly as "Owen" or "OH-in," depending on dialect.

In everyday Irish usage, Seán is the more common Irish form of John in speech, while Eoin is frequently used in writing and formal contexts. The name has also been adopted in English-language contexts by the Irish and their descendants, though Anglicized spellings are less common than the Irish forms.

Notable bearers include Eoin Colfer, an Irish author best known for the Artemis Fowl series, and Eoin Morgan, an Irish-born cricketer who has played for England and captained the national team. The name is used by many others in Ireland and among the Irish diaspora, reflecting the country’s long-standing naming traditions.

Eoin remains a widely recognized and culturally significant Irish given name, associated with Ireland’s linguistic heritage and its enduring connection to the broader family of names derived from Ioannes, including John.
