In folklore and literature, the Fairy Queen or Queen of the Fairies is a female ruler of the fairies, sometimes but not always paired with a king. Depending on the work, she may be named or unnamed; Titania and Mab are two frequently used names. Numerous characters, goddesses or folkloric spirits worldwide have been labeled as Fairy Queens.

Titania is a character in William Shakespeare's 1595–1596 play A Midsummer Night's Dream.
