The black-mantled goshawk (Tachyspiza melanochlamys) is a species of bird of prey in the family Accipitridae.

The black-mantled goshawk was figured in John Gould's The Birds of New Guinea and the Adjacent Papuan Islands, where it was placed in the genus Astur.

[2] The black-mantled goshawk was formally described in 1876 by the Italian zoologist Tommaso Salvadori based on a specimen collected in the Arfak Mountains of western New Guinea.

In 2024 a comprehensive molecular phylogenetic study of the Accipitridae confirmed earlier work that had shown that the genus was polyphyletic.

[9] This species has been treated as polytypic; however, the more recent contention is that it is monotypic, following Bruce Beehler and Thane Pratt.
