Tarqeq (/ˈtɑrkɛk/ TAR-kek), also known as Saturn LII (provisional designation S/2007 S 1) is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on April 13, 2007, from observations taken between January 5, 2006, and March 22, 2007.[1][2] It is named after Tarqeq, the Inuit moon god,[3] and is a member of the Inuit group of irregular satellites. It's about seven kilometres in diameter.[4] The Cassini spacecraft observed Tarqeq over 1.5 days on January 15-16, 2014.

The Tarqiup (Tarqeqian) orbit lies at an inclination of 49.90° (to the ecliptic; 49.77° to Saturn's equator), with an eccentricity of 0.1081[1] and a semi-major axis of 17.9106 Gm. Tarqeq orbits in a prograde direction with a period of 894.86 days.
