Sturt Stony Desert (previously Sturt's Stony Desert) is an area in the north-east of South Australia, far south western border area of Queensland and the far west of New South Wales.

It was named by Charles Sturt in 1844, while he was trying to find the inland sea which he believed lay at the centre of Australia. The stones caused his horses to limp and wore down the hooves of the cattle and sheep which Sturt had taken on the expedition.

The larger Simpson Desert is located to the west and the Strzelecki Desert is to the south east. Between these two dunefields is the Gason Dome, upon which the Sturt Stony Desert is located. To the south west of Sturt Stony Desert is the Tirari Desert. The Birdsville Track is a route between Marree in South Australia and Birdsville in Queensland.

Landscape

Much of the desert is covered by gibber. Sturt suggested the closely compacted stones were the result of currents moving across an ancient seafloor. However the gibber plains originated from desert sandstone sheets which once covered the area. Weather has slowly broken down the sandstone with the harder fragments remaining.

Both circular and stepped gilgai have been found in the desert.

Ecology

The desert is part of the Tirari-Sturt stony desert ecoregion. The desert is home to the Kowari a native, carnivorous marsupial which lives in the sand dunes, soiled areas and occasional areas of swamp, dispersed amongst the gibber.
