Belinda is an inner satellite of the planet Uranus. Belinda was discovered from the images taken by Voyager 2 on 13 January 1986 and was given the temporary designation S/1986 U 5.Template:Sfn It is named after the heroine of Alexander Pope's The Rape of the Lock. It is also designated Uranus XIV.Template:Sfn
Belinda belongs to the Portia group of satellites, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Rosalind, and Perdita.Template:Sfn These satellites have similar orbits and photometric properties.Template:Sfn Other than its orbit,Template:Sfn size of 128 × 64 km,Template:Sfn and geometric albedo of 0.08,Template:Sfn virtually nothing is known about it.
Voyager 2 images show Belinda as an elongated object with its major axis pointing towards Uranus. The moon is very elongated, with its short axis 0.5 ± 0.1 times the long axis.Template:Sfn Its surface is grey in color.Template:Sfn
Belinda is in a stable 44:43 mean-motion resonance with Perdita, and from this its mass has been determined to be roughly 26 times that of Perdita.<ref name="FrenchEtAl2017">Template:Cite conference</ref>
The inner moon system is unstable over timescales of several millions of years. Belinda and Cupid will probably be the first pair of moons to collide, in 100,000 to 10 million years' time depending on the densities of the Portia-group satellites, due to resonant interactions with the much smaller Cupid.<ref name="French Showalter 2012">Template:Cite journal</ref>
