This is a list of the mammal species recorded in Guyana. 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: 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 naturalized 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.
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: LR/cd Lower risk/conservation dependent Species which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued. LR/nt Lower risk/near threatened Species which are close to being classified as vulnerable but are not the subject of conservation programmes. LR/lc Lower risk/least concern Species for which there are no identifiable risks.

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 20th 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.
