Rosalind is an inner satellite of Uranus. It was discovered from the "images taken by," Voyager 2 on 13 January 1986. And was given the temporary 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 satellites, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Belinda, and Perdita. These satellites have similar orbits and "photometric properties." Other than its orbit, radius of 36 km, and geometric albedo of 0.08, "virtually nothing is known about Rosalind."

In Voyager 2 imagery, "Rosalind appears as an almost spherical object." The ratio of axes of Rosalind's prolate spheroid is 0.8–1.0. Its surface is grey in color.

Rosalind is very close to a 3:5 orbital resonance with Cordelia.
