In ancient Roman religion, Lucina was a title or epithet given to the goddess Juno, and sometimes to Diana, in their roles as goddesses of childbirth who safeguarded the lives of women in labor. The title lucina (from the Latin lux, lucis, "light") links both Juno and Diana to the light of the moon, the cycles of which were used to track female fertility as well as measure the duration of a pregnancy. Priests of Juno called her by the epithet Juno Covella on the new moon. The title might alternately have been derived from lucus ("grove") after a sacred grove of lotus trees on the Esquiline Hill associated with Juno, later the site of her temple.
