In September 2016, the International Union for Conservation of Nature (IUCN) listed 783 data deficient mammalian species.^[1] Of all evaluated mammalian species, 14% are listed as data deficient. The IUCN also lists 30 mammalian subspecies as data deficient.

Of the subpopulations of mammals evaluated by the IUCN, four species and/or subpopulations have been assessed as data deficient.

This is a complete list of data deficient mammalian species and subspecies evaluated by the IUCN. Species and subspecies which have data deficient subpopulations (or stocks) are indicated. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.
