There are 84 mammal species (with two uncertain) recorded in Sweden according to the IUCN Red List. Two are endangered, one is vulnerable as well now extinct, and four are near threatened.

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

Even-toed ungulates 

Even-toed ungulates are members of the order Artiodactyla. The even-toed ungulates are ungulates whose weight 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 artiodactyl species, including many that are of great economic importance to humans.

Whales, dolphins and porpoises 

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.

Bats 

Bats are members of the order Chiroptera. The most distinguishing feature of bats 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.

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.

Family: Leporidae

 Mountain hare, Lepus timidus 
 European rabbit, Oryctolagus cuniculus  introduced

Rodents 

Rodents are members of the order Rodentia. 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 .
