The saturnine antshrike (Thamnomanes saturninus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds".

[2] The saturnine antshrike was described by the Austrian ornithologist August von Pelzeln in 1868 and given the binomial name Thamnophilus saturninus.

[3] During the twentieth century several authors placed it in genus Dysithamnus and treated it and what is now the dusky-throated antshrike (T. ardesiacus) as conspecific.

Their throat and upper breast are black and the rest of their underparts darkish gray with usually some white edges on the belly feathers.

It is found south of the Amazon and Marañón rivers in northeastern Peru and into southwestern Amazonian Brazil's Acre state.

The saturnine antshrike's song is an "accelerated, ascending series of notes, at first grating, then gradually changing to sharp and piercing".

[1] It is considered fairly common across its range, which includes some large protected areas and "remains little developed and relatively inaccessible".
