Meaning and origin of Cynthia

Cynthia is a Greek name that means “woman from Mount Kynthos”.

In Greek myth, Artemis was said to have been born on Mount Kynthos on the island of Delos, and poets called her Kynthia after that birthplace. Latin writers kept the title, and because Artemis was linked with the moon, Cynthia became a poetic name for the moon itself in English verse, used by Elizabethan poets as a compliment to Queen Elizabeth I. As an everyday given name it came into its own in the twentieth century and was a favorite of the mid-century era. Today it reads as a polished classic with real mythological roots. Cindy is the traditional nickname, while Cyn and Thea offer fresher options.
