Euphrosyne (/juːˈfrɒzɪni/; Εὐφροσύνη), in ancient Greek religion, was one of the Charites, known in English as the "Three Graces". She was usually called Euthymia (Εὐθυμία) or Eutychia (Εὐτυχία).

According to Greek myth, Euphrosyne and the two other Charites were daughters of Zeus and the Oceanid Eurynome. The Greek poet Pindar states that these goddesses were created to fill the world with pleasant moments and good will. Usually the Graces attended the goddess of beauty Aphrodite and her companion Eros and loved dancing around in a circle to Apollo's divine music, together with the Nymphs and the Muses. Euphrosyne is usually depicted with her sisters.

Euphrosyne is a Goddess of Good Cheer, Joy and Mirth, and the incarnation of grace and beauty. The other two Charites are Thalia (Festivity or Blooming) and Aglaea (Beauty or Splendor). Her half-brother is Hephaistos, or Hephaestus, the god of metalworking and volcanoes. Her name is the female version of a Greek word euphrosynos, which means "merriment".

In Roman myths the Graces where known as the "Gratiae".
