Polydeuces (pol'-ee-dew'-seez, IPA /ˈpɑliˈdjuːsiz/, Greek Πολυδεύκης) is a natural satellite of Saturn that was discovered in images taken on October 21, 2004 by the Cassini imaging team and given the temporary designation S/2004 S 5. It is co-orbital with Dione and is located in the trailing Lagrangian point (L₅). Its diameter is estimated to be about 3.5 km. It is also designated as Saturn XXXIV.

Of the known Lagrangian co-orbitals in the Saturn system, Polydeuces wanders the most from the Lagrangian point, straying up to 32 degrees from L₅.

The name Polydeuces was approved by the IAU Working Group on Planetary System Nomenclature on January 21, 2005. In Greek mythology, Polydeuces is another name for Pollux, twin brother of Castor, son of Zeus and Leda.
