Trinculo (/ˈtrɪŋkjʊloʊ/ TRING-kew-loh) is a retrograde irregular satellite of Uranus. It was discovered by a group of astronomers led by Holman, et al. on 13 August 2001, and given the temporary designation S/2001 U 1.[1][7]
Confirmed as Uranus XXI, it was named after the drunken jester Trinculo in William Shakespeare's play The Tempest.
