A quail-thrush is a bird of the genus Cinclosoma, which contains eight species. Quail-thrushes are in a different family from either quails or thrushes, but bear some superficial resemblance to them. The genus is found in Australia and New Guinea in a variety of habitats ranging from rainforest to deserts.
The genus Cinclosoma was introduced in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield to accommodate a single species, Turdus punctatus Latham 1801, which becomes the type species by monotypy This is a junior synonym of Turdus punctatus Shaw, 1794, the spotted quail-thrush. The genus name combines the Modern Latin cinclus meaning "thrush" with the Ancient Greek úùóúûÿÃÂ/kinklos, an unidentified tail-wagging waterside bird.
The genus is closely related to the jewel-babblers of New Guinea. A molecular study published in 2015 by Gaynor Dolman and Leo Joseph resulted in the splitting of the chestnut-backed quail-thrush into the chestnut quail-thrush of eastern Australia and the copperback quail-thrush in the west.
The genus contains eight species:
