This is a list of Uranus' 27 moons. They are listed by how long they take to orbit (go around once) Uranus. They are all named after characters created by William Shakespeare and Alexander Pope.

Notes: * Negative orbital periods indicate a retrograde orbit around Uranus (opposite to the planet's rotation).
