This is a list of the mammal species recorded in the Cook Islands. There are seven mammal species in the Cook Islands, of which one is labelled as being a vulnerable species.This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD). The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institution, or University of Michigan where no Wikipedia article was available. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:
