Setebos Template:IPAc-en is one of the outermost retrograde irregular satellites of Uranus. It was discovered on 18 July 1999 by John J. Kavelaars et al. and provisionally designated S/1999 U 1.<ref name="Gladman Discovery 2000" />

Confirmed as Uranus XIX, it is named after the god Setebos worshipped by Caliban and Sycorax in William Shakespeare's play The Tempest.

The orbital parameters suggest that it may belong to the same dynamic cluster as Sycorax and Prospero, suggesting common origin.<ref name="Grav2003" /> However, this suggestion does not appear to be supported by the observed colours. The satellite appears neutral (grey) in visible light (colour indices Template:Nobr Template:NobrTemplate:Sfn similar to Prospero but different from Sycorax (which is light red).

A crater on Umbriel is also named after Setebos, but with the spelling Setibos.
