Suttungr/ˈsʊtʊŋər/, orSaturn XXIII, is anatural satellite ofSaturn. It was discovered byBrett J. Gladman, et al. in 2000, and given the temporary designationS/2000 S 12. It was named forSuttungr inNorse mythology, aJötunn or giant who once owned themead of poetry.

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 offPhoebe. The Suttung orbit isretrograde, at aninclination of 174° to theecliptic (151° to Saturn's equator) and with aneccentricity of 0.131. Its rotation period is7.67±0.02 hours, and likeAlbiorix itslight curve exhibits two minima at certain angles, and three minima at others.^[3] Having a similar gray color and orbit asThrymr, the two moons may be members of the same dynamical family.^[4]

Its name was announced in itsoblique formSuttung inIAU Circular 8177. However, theIAU Working Group on Planetary System Nomenclature later decided to add thenominative suffix-r to the base formSuttung.
