Orcininae is a contested subfamily of oceanic dolphins composed of 1 living and 3 extinct genera.{{cite web |title=Subfamily Orcininae Wagner 1846 (dolphin) |url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=63527 |website=Fossilworks.org}}{{cite web |title=Cetaceans of the world |url=http://www.marinespecies.org/cetacea/aphia.php?p=taxdetails&id=383337}} It may be superseded by Delphinidae.{{cite WoRMS|title=Orcininae|id=383337|db=Cetacea|access-date=4 August 2018}} Its only extant member is the orca (Orcinus orca); all other extant genera formerly classified in it have been moved out.{{cite journal | vauthors = McGowen MR, Tsagkogeorga G, Álvarez-Carretero S, Dos Reis M, Struebig M, Deaville R, Jepson PD, Jarman S, Polanowski A, Morin PA, Rossiter SJ | display-authors = 6 | title = Phylogenomic Resolution of the Cetacean Tree of Life Using Target Sequence Capture | journal = Systematic Biology | volume = 69 | issue = 3 | pages = 479–501 | date = May 2020 | pmid = 31633766 | pmc = 7164366 | doi = 10.1093/sysbio/syz068 }}

Orcininae is thought to be one of the most basal members of Delphinidae, with only the Atlantic white-sided dolphin (Lagenorhynchus acutus) being more basal.{{Cite journal|last=McGowen|first=Michael R|last2=Tsagkogeorga|first2=Georgia|last3=Álvarez-Carretero|first3=Sandra|last4=dos Reis|first4=Mario|last5=Struebig|first5=Monika|last6=Deaville|first6=Robert|last7=Jepson|first7=Paul D|last8=Jarman|first8=Simon|last9=Polanowski|first9=Andrea|last10=Morin|first10=Phillip A|last11=Rossiter|first11=Stephen J|date=2019-10-21|title=Phylogenomic Resolution of the Cetacean Tree of Life Using Target Sequence Capture|url=https://doi.org/10.1093/sysbio/syz068|journal=Systematic Biology|volume=69|issue=3|pages=479–501|doi=10.1093/sysbio/syz068|issn=1063-5157|pmc=7164366|pmid=31633766}}
