Orcinus
Orcinus is a genus of Delphinidae (dolphins), in the clade Cetacea. It includes the largest (and only extant) delphinoid species, Orcinus orca, known as the orca or killer whale. Two extinct species are recognized, Orcinus paleorca and O. citoniensis, known from fossils. The other extinct species O. meyeri is disputed.

Orcininae is a contested subfamily of oceanic dolphins composed of 1 living and 3 extinct genera. It may be superseded by Delphinidae. Its only extant member is the orca (Orcinus orca); all other extant genera formerly classified in it have been moved out.
