Rosalind is a closer moon to Uranus. It was found from the images taken by Voyager 2 on January 13, 1986, and was given the designation S/1986 U 4. It was named after the daughter of the banished Duke in William Shakespeare's play As You Like It. It is also designated Uranus XIII.

Rosalind belongs to Portia Group of moons, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Belinda and Perdita. These moons have similar orbits and photometric properties. Unfortunately, other than its orbit, radius of 36 km and geometric albedo of 0.08 almost nothing is known about it.

At the Voyager 2 images Rosalind appears as an almost spherical object. The ratio of axises of the Rosalind's prolate spheroid is 1.0-0.8. Its surface is grey in color.
