Currently, 27 moons, or satellites, have been discovered around Uranus.
The largest moon one is named Titania and its diameter is half the diameter of our moon. Other moons in our solar system are named after Greek or Roman mythological characters, but most of the moons of Uranus are named after characters from the world of William Shakespeare.

The two moons that are not named as such are Arlel and Umbriel. They are the names of characters in the book The Rape of the Lock by Alexander Pope.
