Calypso (ka-lip'-soe, Greek Καλυψώ) is a moon of Saturn. It was discovered by Pascu, Seidelmann, Baum and Currie in 1980 from ground-based observations, and was designated 1980 S 25. In 1983 it was officially named after Calypso of Greek mythology. It is also designated as Saturn XIV.
Calypso is co-orbital with the moon Tethys, and resides in Tethys' trailing Lagrangian point (L5). The moon Telesto resides in Tethys' leading Lagrangian point.
Not to be confused with asteroid 53 Kalypso.
