Queen Mab is a fairy referred to in William Shakespeare's play Romeo and Juliet, in which the character Mercutio famously describes her as "the fairies' midwife", a miniature creature who rides her chariot over the bodies of sleeping humans during the nighttime, thus helping them "give birth" to their dreams. Later depictions in other poetry and literature and various guises in drama and cinema have typically portrayed her as the Queen of the Fairies.
