Béḃinn, or Befind, is alternately described as either the wife of Áed Alainn, a god, or Idath, a mortal man. She is mentioned in multiple sources as the mother of Connacht hero Fráech, the main character in the Táin Bó Fraích. In the Fenian Cycle of Irish tales, Béḃinn is "a beautiful giantess of aristocratic bearing" who seeks protection from the Fianna when an ugly giant pursues her. In other sources, a Béḃinn is mentioned as a daughter of Elcmar.
The epithet Bé Find ("Fair Woman") is applied to the heroine Étaín by Midir in Tochmarc Étaíne (English: The Wooing of Étaín). The text includes a poem attributed to Midir, known as "A Bé Find in ragha lium". However, this poem may be an older composition unrelated to the Étaín story that was appended at a later time.
