List of mammals of Antarctica
This is a list of the mammal species recorded in Antarctica. There are 17 mammal species in Antarctica, all of which are marine mammals. Three of these species are considered to be endangered, and four are listed as data deficient. Domesticated species, such as the dogs formerly present, are not included.
The following tags are used to highlight each species' conservation status as assessed by the IUCN:
|EX||Extinct||No reasonable doubt that the last individual has died.|
|EW||Extinct in the Wild||Known only to survive in captivity or as a naturalized population well outside its historic range.|
|CR||Critically Endangered||The species is facing an extremely high risk of extinction in the wild.|
|EN||Endangered||The species is facing a very high risk of extinction in the wild.|
|VU||Vulnerable||The species is facing a high risk of extinction in the wild.|
|NT||Near Threatened||The species does not currently qualify as being at high risk of extinction but it is likely to do so in the future.|
|LC||Least Concern||The species is not currently at risk of extinction in the wild.|
|DD||Data Deficient||There is inadequate information to assess the risk of extinction for this species.|
Subclass: Theria 
Infraclass: Eutheria 
Order: Carnivora (carnivorans) 
There are over 260 species of carnivorans, the majority of which feed primarily on meat. They have a characteristic skull shape and dentition. The southern elephant seal is believed to be the largest carnivoran of all time.
- Suborder: Caniformia
- Family: Phocidae (earless seals)
Order: Cetacea (whales) 
The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater. Their closest extant relatives are the hippos, which are artiodactyls, from which cetaceans are believed to have descended (as reflected in the naming of the clade Cetartiodactyla).
- Suborder: Mysticeti
- Family: Balaenidae
- Family: Balaenopteridae
- Suborder: Odontoceti
- Superfamily: Platanistoidea
- Family: Phocoenidae
- Family: Ziphidae
- Family: Delphinidae (marine dolphins)
- Superfamily: Platanistoidea

- This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD). The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institute, or University of Michigan where no Wikipedia article was available.
