Colleen is a girl’s name of Irish origin that means, appropriately, “girl.” The Anglicization of the Irish given name Cailín, Colleen comes from the Old Irish word caile, meaning “woman,” “countrywoman,” or “wench.” Irish mythology enthusiasts will be drawn to caile’s close association with the Cailleach. “Old woman” in Irish, the Cailleach is a divine hag and wise woman said to have created the Celtic landscape. With the name Colleen, baby will lead a life of creativity and wisdom as she grows from a girl to an old woman.
