Catocala is a generally Holarctic genus of moths in the Erebidae family. The moths are commonly known as underwing moths or simply underwings. These terms are sometimes used for a few related moths, but usually – especially when used in plural, not as part of a species name – they are used to refer to Catocala only.

Of the more than 250 known species, slightly less than half are found in North America – mostly in the United States – while the rest occur in Eurasia. About one-fifth (almost 30) of these species are native to Europe. A few species occur in the northern Neotropics and Indomalaya.
