Orcininae
Scientific classification
Kingdom:	Animalia
Phylum:	Chordata
Class:	Mammalia
Order:	Artiodactyla
Infraorder:	Cetacea
Family:	Delphinidae
Subfamily:	Orcininae

Orcininae is a contested subfamily of oceanic dolphins composed of 1 living and 3 extinct genera. ^{[1] [2]} It may be superseded by Delphinidae. ^[3] Its only extant member is the orca (Orcinus orca); all other extant genera formerly classified in it have been moved out. ^[4]

The Atlantic white-sided dolphin (Leucopleurus acutus) is sister to all other members of the Delphinidae; within that clade, the Orcininae are sister to all remaining lineages. ^[5]
