Helene ("HELL uh nee" or "hel LEE nee") is a moon of Saturn. It was discovered by Pierre Laques and Jean Lecacheux in 1980 from ground-based observations at Pic du Midi Observatory, and was designated 1980 S 6. In 1988 it was officially named after Helene of Greek mythology.

It is co-orbital with Dione and located in its leading Lagrangian point (L₄) and hence, before it received its permanent name of "Helene" it was usually referred to as "Dione B".
