The brown goshawk (Tachyspiza fasciata) is a medium-sized bird of prey in the family Accipitridae found in Australia and surrounding islands.

The brown goshawk was formally described in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield under the binomial name Astur fasciatus.

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

[8] Thirteen subspecies are recognised:[6] Its upperparts are grey with a chestnut collar; its underparts are mainly rufous, finely barred with white.

However, the lack of specimens from Norfolk Island (1 historical skin and 9 subfossil bones is all the material that has been found)[9] means that no genetic test can be conducted.

Brown goshawks often hunt near farmland or wetlands, where birds such as ducks, cockatoos and pigeons are plentiful.
