This is a list of the mammal species recorded in Gibraltar. There are twenty-four mammal species in Gibraltar, of which one is critically endangered, one is endangered, three are vulnerable, and one is near threatened.[1]
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:
| Extinct | No reasonable doubt that the last individual has died. | ||
| Extinct in the wild | Known only to survive in captivity or as a naturalized populations well outside its previous range. | ||
| Critically endangered | The species is in imminent risk of extinction in the wild. | ||
| Endangered | The species is facing an extremely high risk of extinction in the wild. | ||
| Vulnerable | The species is facing a high risk of extinction in the wild. | ||
| 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. | ||
| Least concern | There are no current identifiable risks to the species. | ||
| Data deficient | There is inadequate information to make an assessment of the risks to this species. |
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.
