List of scandentians

Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the scandentian's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".

The order Scandentia consists of two families: Tupaiidae, which contains twenty-two species within three genera, and Ptilocercidae, which contains a single species. Many of these species are further subdivided into subspecies. This does not include hybrid species or extinct prehistoric species.

The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis.^[2]
