Skoll, or Saturn XLVII (provisional designation S/2006 S 8), is a retrograde irregular satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt and Jan Kleyna on 26 June 2006 from observations taken between 5 January and 30 April 2006.

Skoll is about 5 kilometres in diameter (assuming an albedo of 0.06) and orbits Saturn at an average distance of 17.6 Gm (million km) in 869 days, following a highly eccentric and moderately inclined orbit. A rotation period of 7.26±0.04 h was obtained by Cassini–Huygens in 2016, but this is in strong disagreement with 2013 data for unknown reasons; one possible explanation is variation in the rotation speed and axis due to Milankovitch wobble.
