'''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&nbsp;U&nbsp;4'''.<ref name="IAUC 4164" /> It was named after the daughter of the banished Duke in [[William Shakespeare]]'s play ''[[As You Like It]]''. It is also designated '''Uranus&nbsp;XIII'''.<ref name="Gazetteer" />

Rosalind belongs to Portia group of satellites, which also includes [[Bianca (moon)|Bianca]], [[Cressida (moon)|Cressida]], [[Desdemona (moon)|Desdemona]], [[portia (moon)|Portia]], [[Juliet (moon)|Juliet]], [[Cupid (moon)|Cupid]], [[Belinda (moon)|Belinda]], and [[Perdita (moon)|Perdita]].<ref name="Karkoschka, Hubble 2001" /> These satellites have similar orbits and photometric properties.<ref name="Karkoschka, Hubble 2001" /> Other than its orbit,<ref name="Jacobson 1998" /> radius of 36&nbsp;km,<ref name="Karkoschka, Voyager 2001" /> and [[geometric albedo]] of 0.08,<ref name="Karkoschka, Hubble 2001" /> 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.<ref name="Karkoschka, Voyager 2001" /> Its surface is grey in color.<ref name="Karkoschka, Voyager 2001" />

Rosalind is very close to a 3:5 [[orbital resonance]] with [[Cordelia (moon)|Cordelia]].<ref name="Murray Thompson 1990" />
