The endemic Azores noctule (Nyctalus azoreum) is, along with the greater mouse-eared bat (Myotis myotis), the only current native mammal of the Azores that is not a cetacean.

This is a list of the mammal species recorded in the Azores Islands, Portugal.[1] One of the most remote archipelagos in Europe, the Azores were completely devoid of mammals prior to their discovery in the early 15th century, except for marine mammals and two species of bats, and all present terrestrial mammals in the islands are therefore introduced.

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 populations well outside its previous range.
CR Critically endangered The species is in imminent risk of extinction in the wild.
EN Endangered The species is facing an extremely 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 meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future.
LC Least concern There are no current identifiable risks to the species.
DD Data deficient There is inadequate information to make an assessment of the risks to this species.

Subclass: Theria[edit]

Infraclass: Eutheria[edit]

Order: Rodentia (rodents)[edit]

Rodents make up the largest order of mammals, with over 40 percent of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be keep short by gnawing. Most rodents are small though the capybara can weigh up to 45 kg (100 lb).

Order: Erinaceomorpha (hedgehogs and gymnures)[edit]

The order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures. The hedgehogs are easily recognised by their spines while gymnures look more like large rats.

Order: Chiroptera (bats)[edit]

The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals in the world naturally capable of flight. Bat species account for about 20% of all mammals.

Order: Cetacea (whales)[edit]

Sperm whale and calf

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. Many species of cetaceans reproduce around the Azores.

Order: Carnivora (carnivorans)[edit]

There are over 260 species of carnivorans, the majority of which feed primarily on meat. They have a characteristic skull shape and dentition.
