Belinda (pronounced /bɨˈlɪndə/ bə-LIN-də) 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.[7] It is named after the heroine of Alexander Pope's The Rape of the Lock. It is also designated Uranus XIV.[8]

Belinda belongs to the Portia Group of satellites, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Rosalind and Perdita.[6] These satellites have similar orbits and photometric properties.[6] Other than its orbit,[1] radius of 45 km[2] and geometric albedo of 0.08[6] virtually nothing is known about it.

The 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.[2] Its surface is grey in color.[2]
