Suttungr /ˈsʊtʊŋər/, or Saturn XXIII, is a natural satelliteofSaturn. It was discovered by Brett J. Gladman, et al. in 2000, and given the temporary designation S/2000 S 12. It was named for SuttungrinNorse mythology, a Jötunn or giant who once owned the meadofpoetry.

Suttungr is about 7 kilometres in diameter, and orbits Saturn at an average distance of 19,667 Mm in 1029.703 days. It may have formed from debris knocked off Phoebe. The Suttung orbit is retrograde, at an inclination of 174° to the ecliptic (151° to Saturn's equator) and with an eccentricity of 0.131. Its rotation period is 7.67±0.02 hours, and like Albiorix its light curve exhibits two minima at certain angles, and three minima at others.[3] Having a similar gray color and orbit as Thrymr, the two moons may be members of the same dynamical family.[4]

Its name was announced in its oblique form SuttunginIAU Circular 8177 Archived 2008-07-09 at the Wayback Machine. However, the IAU Working Group on Planetary System Nomenclature later decided to add the nominative suffix -r to the base form Suttung.
