S/2004 S 13 is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 4 May 2005 from observations taken between 12 December 2004 and 9 March 2005.

S/2004 S 13 is about 6 kilometres in diameter, and orbits Saturn at an average distance of 18,056 Mm in 905.848 days, at an inclination of 167° to the ecliptic (143° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.261.

This moon has not been seen since its discovery in 2004 and is currently considered lost.[3][4][5]
