S/2007 S 3 is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 1 May 2007 from observations taken between 18 January and 19 April 2007.

S/2007 S 3 is about 5 kilometres in diameter, and orbits Saturn at an average distance of 19,429,000 kilometres in about 1,011 days, at an inclination of 176.6° to the ecliptic, in a retrograde direction and with an eccentricity of 0.143.[2][4]

This moon was considered lost[5] until its recovery was announced on 12 October 2022.[2]
