This is a list of the mammal species recorded in Denmark, listing only species found outside captivity and fenced enclosures, or with certain records younger than 1000 A.D. The main source is the most recent atlas survey of mammals in Denmark. [1] The atlas records 88 mammal species in Denmark. Since the atlas was published in 2007, three new species have been recorded in the country: the grey wolf, [2] golden jackal [3] and Cuvier's beaked whale. [4]
The following tags are used to highlight each species' conservation status in the most current version of the Danish Red List. [3] Assessments were made following recommendations of the International Union for Conservation of Nature.
| 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. |
| RE | Regionally extinct | No reasonable doubt that the species no longer exist in the assessed region and is extirpated. |
| 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. |
| NA | Not assessed | Not assessed, either because it is an invading/naturalised species, or extremely rare visitor |
