Oberon (also spelled Auberon) is a king of the fairies in medieval and Renaissance literature. He is best known as a character in William Shakespeare's play A Midsummer Night's Dream. In this play, he is married to Titania, the Queen of the Fairies. His servant is Puck. Puck plays tricks.
In the play, Oberon and Titania are arguing. Titania falls asleep. Oberon tells Puck to put a potion in her eyes. This potion will make her love the first thing she sees when she wakes. She sees a man with a donkey head. Oberon and Titania make up. All ends happily.
