List of mammals in Costa Rica

This is a list of the mammal species recorded in Costa Rica. There are 212 mammal species in Costa Rica, of which 1 is critically endangered, 4 are endangered, 6 are vulnerable, and 3 are near-threatened. [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 Institute, 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 IUCN:

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: Lagomorpha (lagomorphs)

-----The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas). Though they can resemble rodents, and were classified as a superfamily in that order until the early twentieth century, they have since been considered a separate order. They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.
