This is a list of the mammal species recorded in Argentina. As of February 2011, the list contains 398 mammal species from Argentina, of which 1 is extinct, 6 are critically endangered, 14 are endangered, 19 are vulnerable, and 31 are near-threatened.
The following tags are used to highlight each species' conservation status as assessed by the IUCN:
Order: Didelphimorphia (common opossums)
Didelphimorphia is the order of common opossums of the Western Hemisphere. Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene.They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail.

There are six extant species of shrew opossum. They are small shrew-like marsupials confined to the Andes.
Family: Caenolestidae
Genus: Rhyncholestes
Long-nosed caenolestid Rhyncholestes raphanurus NT
Order: Microbiotheria (monito del monte)
The monito del monte is the only extant member of its family and the only surviving member of an ancient order, Microbiotheria. It appears to be more closely related to Australian marsupials than to other Neotropic marsupials; this is a reflection of the South American origin of all Australasian marsupials.
Family: Microbiotheriidae
Genus: Dromiciops

Order: Cingulata (armadillos)
Armadillos are small mammals with a bony armored shell. There are 21 extant species in the Americas, 19 of which are only found in South America, where they originated. Their much larger relatives, the pampatheres and glyptodonts, once lived in North and South America but became extinct following the appearance of humans.

The order Pilosa is extant only in the Americas and includes the anteaters, sloths, and tamanduas. Their ancestral home is South America. Numerous ground sloths, some of which reached the size of elephants, were once present in both North and South America, as well as on the Antilles, but all went extinct following the arrival of humans.

Order: Lagomorpha (lagomorphs)
The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas). Though they can resemble rodents, and were classified as a superfamily in that order until the early 20th century, they have since been considered a separate order. They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.

Order: Perissodactyla (odd-toed ungulates)
The odd-toed ungulates are browsing and grazing mammals. They are usually large to very large, and have relatively simple stomachs and a large middle toe. South America once had a great diversity of ungulates of native origin, but these dwindled after the interchange with North America, and disappeared entirely following the arrival of humans. Sequencing of collagen from fossils of one recently extinct species each of notoungulates and litopterns has indicated that these orders comprise a sister group to the perissodactyls.
Family: Tapiridae (tapirs)
Genus: Tapirus
Lowland tapir Tapirus terrestris VU
Order: Artiodactyla (even-toed ungulates and cetaceans)
The weight of even-toed ungulates is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 noncetacean artiodactyl species, including many that are of great economic importance to humans.

Infraorder: Cetacea (whales, dolphins and porpoises)
The infraorder 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 descended; cetaceans are thus also artiodactyls.
