हेलेन (Helene) (/ˈhɛlɨniː/ HEL-ə-nee; यूनानी : Ἑλένη), शनि का एक प्राकृतिक उपग्रह है । यह 1980 में पियरे लैक्युस और जीन लेकाच्युक्स द्वारा पिक डू मिडी वेधशाला में भूआधारित प्रेक्षणों से खोजा गया तथा S/1980 S 6 पदनाम से नवाजा गया था ।^[3] In 1988 it was officially named after Helen of Troy, who was the granddaughter of Cronus (Saturn) in Greek mythology.^[4] The moon is also designated Saturn XII (12), a number which it received in 1982, under the designation Dione B, because it is co-orbital with Dione and located in its leading Lagrangian point (साँचा:L4). It is one of four known trojan moons.
