Saturnia is a genus of large silkmoths in the family Saturniidae, which the German biologist Franz von Paula Schrank first described in 1802. Its members are commonly named emperor moths, though this is also used for various close relatives in subfamily Saturniinae. The known species are found across the Palearctic. However, three allied species, commonly called "saturnia moths" inhabit the chaparral of California. These have been included as species of the genus Saturnia in some schemes, but recently are treated as a separate genus Calosaturnia, only in the United States.
Else, the BrazilianArsenura pandora has been previously placed in the genus Saturnia. Whether the autumn emperor moth (Perisomena caecigena), should be included in Saturnia needs to be determined; the same goes for the genus Neoris.
