Skoll (/ˈskɒl/ SKOL; Norse [skœlː]) 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.^[2]^[4]

Skoll is about 6 kilometres in diameter (assuming an albedo of 0.04)^[3] and orbits Saturn at an average distance of 17.6 Gm (million km) in 869 days, following a highly eccentric and moderately inclined orbit.

It was named in April 2007^[5] after Sköll, a giant wolf from Norse mythology, son of Fenrisulfr and twin brother of Hati.
