As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3117 least concern mammalian species. 56% of all evaluated mammalian species are listed as least concern. The IUCN also lists 127 mammalian subspecies as least concern. Of the subpopulations of mammals evaluated by the IUCN, one species subpopulation has been assessed as least concern. This is a complete list of least concern mammalian species and subspecies evaluated by the IUCN. Species and subspecies which have least concern subpopulations (or stocks) are indicated. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.
