List of mammals of Seychelles

This is a list of the mammal species recorded in the Seychelles. Of the mammal species in the Seychelles, two are critically endangered and two are vulnerable.

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.

Family: Dugongidae
- Genus: Dugong

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.

Family: Pteropodidae (flying foxes, Old World fruit bats)
- Subfamily: Pteropodinae
  - Genus: Pteropus
    - Aldabra flying fox, Pteropus aldabrensis CR
