A '''dunnart''' (from Noongar ''donat''<ref>{{Cite journal |last=Abbott |first=Ian |date=2001 |title=Aboriginal names of mammal species in south-west Western Australia |url=https://library.dbca.wa.gov.au/static/Journals/080273/080273-03.019.pdf |journal=CALMScience |volume=3 |issue=4 |pages=450–451}}</ref>) is a narrow-footed marsupial the size of a European mouse, of the genus '''''Sminthopsis'''''. Dunnarts have a largely insectivorous diet.

The genus name ''Sminthopsis'' was published by Oldfield Thomas in 1887, the author noting that the name ''Podabrus'' that had previously been used to describe the species was preoccupied as a genus of beetles.<ref name="Divljan2015">{{cite journal |last1=Divljan |first1=Anja |last2=Ingleby |first2=Sandy |last3=Parnaby |first3=Harry |s2cid=30027103 |title=Taxonomic status of ''Podabrus albocaudatus'' Krefft, 1872 and declaration of ''Sminthopsis granulipes'' Troughton, 1932 (Marsupialia: Dasyuridae) as a protected name for the White-tailed Dunnart from Western Australia |journal=Zootaxa |date=6 January 2015 |volume=3904 |issue=2 |pages=283–292 |doi=10.11646/zootaxa.3904.2.7 |pmid=25660785 |language=en |issn=1175-5334|doi-access=free }}</ref> The type species is ''Phascogale crassicaudata'', published by John Gould in 1844.
