The Carpentarian grasswren (Amytornis dorotheae) is a species of bird in the family Maluridae. It is endemic to Australia.
Its natural habitat is subtropical or tropical dry shrubland. It is threatened by habitat loss. The habitat of this species is almost exclusively on top of sandstone escarpments in the Northern Territory. In this very difficult to access terrain it is found to be not so rare. This habitat is not endangered by human encroachment other than by fires because of the extreme inaccessibility.
