This is a list of the mammal species recorded in Puerto Rico. These are the mammal species in Puerto Rico, of which one is critically endangered, none are endangered, two are vulnerable, and none are near threatened. Two of the species listed for Puerto Rico are considered to be extinct.

The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:

Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories:

Order: Sirenia (manatees and dugongs)

Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered.

Order: Rodentia (rodents)

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

Order: Primates

The order Primates includes the lemurs, monkeys, and apes, with the latter category including humans.

Order: Chiroptera (bats)

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

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.

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.

Order: Artiodactyla (even-toed ungulates)

The even-toed ungulates are ungulates – hoofed animals – which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly.
