Origin: Irish

Meaning: Little deer

Oisin is a marvelous boy's name of Irish origin. Borrowed from the Irish word oss, it means "little deer," but its star power doesn't stop there. In Irish folklore, Oisin was a famous poet and the demigod son of the mythical hero Fionn Mac Cumhaill. Praised for his strong sense of justice, it was only in his innocent search for eternal youth that he met his eventual demise. The legendary Oisin may not be here to share his wisdom and poetic skill with your little one, but his legacy lives on in those who carry his name.
