Miranda, ook bekend as Uranus V, is die kleinste en binneste van Uranus se vyf ronde mane. Dit is op 16 Februarie 1948 deur Gerard Kuiper ontdek en genoem na Miranda in William Shakespeare se toneelstuk The Tempest.[5] Nes die ander groot mane van Uranus wentel Miranda naby aan die planeet se ewenaarvlak. Omdat Uranus op sy sy om die Son wentel, is Miranda se wentelbaan loodreg met die sonnebaan.
