# List of mammals of the Solomon Islands archipelago

This is a list of the mammal species recorded in the Solomon Islands archipelago. The geographical area covered by this article refers to the archipelago of the Solomon Islands, which includes Bougainville Island, a province of Papua New Guinea, as well as the group of islands that make up the nation state of Solomon Islands. Within this area there are sixty-three mammal species of which four are critically endangered, one is endangered, and fifteen are vulnerable.
Three of the species listed for the Solomon Islands are considered to be extinct.
The marine mammals of the order Cetacea that have been identified in the Pacific is described in the literature review by Miller (2006) and by the Secretariat of the Pacific Regional Environment Programme (SPREP). A revision of the list of cetaceans reported in the ocean surrounding the Solomon Islands was carried by Miller (2009).
The following tags are used to highlight each species' conservation status as assessed by 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 naturalised 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. |
