This is a list of estimated global populations of Marsupials (infraclass Marsupialia) species. This list is not comprehensive, as not all Marsupials have had their numbers quantified.
Some members of Marsupialia are extinct, and thus have population sizes of zero:
Thylacine (Thylacinus cynocephalus) - last recorded wild individual captured in 1933, and died in captivity in 1936. Liverpool Plains striped bandicoot (Perameles fasciata) - went extinct in 1840s. Marl (Perameles myosuros) - last seen in 1907, extinct circa 1910. South-eastern striped bandicoot (Perameles notina) - extinct sometime in late 19th century. Nullarbor barred bandicoot (Perameles papillon) - formerly considered a subspecies of P. bougainville. Last record from 1920s, believed to have gone extinct circa 1928. Desert bandicoot (Perameles eremiana) - last confirmed record from 1943. Unconfirmed reports persisted into the late 1960s. Southern pig-footed bandicoot (Chaeropus ecaudatus) - last specimen collected in 1900, but likely persisted into the 1930s. Northern pig-footed bandicoot, or Yirratji (Chaeropus yirratji) - likely went extinct in the 1950s. Lake Mackay hare-wallaby, or Kuluwarri (Lagorchestes asomatus) - known from a single specimen taken in 1932. Likely went extinct by 1960. Eastern hare-wallaby (Lagorchestes leporides) - last recorded in 1890. Toolache wallaby (Notamacropus greyi) - last confirmed records from 1924; species persisted in captivity until 1939. Some unconfirmed reports were made as late as the 1970s, but could not be verified. Crescent nail-tailed wallaby (Onychogalea lunata) - no confirmed records since 1940s. Estimated to have gone extinct circa 1963. Desert bettong (Bettongia anhydra) - known from a single specimen collected in 1933. Likely went extinct circa 1960. Nullarbor dwarf bettong (Bettongia pusilla) - first described in 1997, but is expected to have been extant at the time of European settlement in Oceania. Desert rat-kangaroo (Caloprymnus campestris) - last confirmed record from 1935; unconfirmed reports have occurred as recently as 2013, but species has not been found despite extensive searches. Broad-faced potoroo (Potorous platyops) - last recorded in 1875. Crest-tailed mulgara (Dasycercus cristicauda) - last confirmed sighting occurred in 1867. Species has historically been taxonomically confused with Dasycercus hillieri, to which all extant populations of the species complex are now consigned.
