Rosalind (roz'-ə-lənd, IPA: [ˈrɒzələnd]) is an inner satellite of Uranus. It was named after the daughter of the banished Duke in William Shakespeare's play As You Like It. Other than its size and orbit, virtually nothing is known about it. It is also designated Uranus XIII.[2]
It was discovered from the images taken by Voyager 2 on 1986-01-13, and was given the temporary designation S/1986 U 4.[3]
