The sandhill grasswren (Amytornis oweni) is an insectivorous bird in the Australasian wren family Maluridae.

The sandhill grasswren was formally described in 1911 by the Australian born ornithologist Gregory Mathews based on a specimen collected in East Murchison of Western Australia.

He considered his specimen to represent a subspecies of the striated grasswren and coined the trinomial name Amytornis striatus oweni.

[1][2] He chose the specific epithet to honour his son-in-law Colonel Richard Owen Wynne.

It is now treated as a separate species based on differences in morphology and ecology.
