Orcinus (/ɔːrˈsaɪnəs/) is a genus of Delphinidae (dolphins), in the infraorder 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.
