The brush-tailed mulgara (Dasycercus blythi or Dasycercus hillieri) is a large carnivorous Australian marsupial species. Its body mass is over 100 g, with males being slightly larger than females. Their body length is 15 cm, and tail length is 9 cm. The taxonomy of the mulgaras has been confusing, but as of 2006, two species are recognized: this species and the crest-tailed mulgara.
