In Greek mythology, Iolë was the daughter of Eurytus, king of the city Oechalia. According to the brief epitome in the Bibliotheca, Eurytus had a beautiful young daughter named Iole who was eligible for marriage. Iole was claimed by Heracles for a bride, but Eurytus refused her hand in marriage. Iole was indirectly the cause of Heracles's death because of his wife's jealousy of her.
