Trinculo (pronounced /ˈtrɪŋkjʊloʊ/ TRING-kew-loh) is a retrograde irregular satellite of Uranus. It was discovered by Holman, et al. on 2001-08-13, and given the temporary designation S/2001 U 1.[3][4]
Confirmed as Uranus XXI, it was named after the drunken jester Trinculo in William Shakespeare's play The Tempest.
