Titania is the largest moon of Uranus. Titania was discovered on January 11, 1787 by William Herschel. All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Names for the first four discovered moons of Uranus, Oberon, Titania, Ariel and Umbriel, were given by John Herschel, the son of William. Titania was named after Titania, the Queen of the Faeries in A Midsummer Night's Dream.

Titania is composed of roughly 50% water ice, 30% silicate rock, and 20% methane-related organic compounds. A major surface feature is a huge canyon that dwarfs the scale of the Grand Canyon on Earth and is in the same class as the Valles Marineris on Mars or the Ithaca Chasma[?] on Saturn's moon Tethys.
