The grey goshawk (Tachyspiza novaehollandiae) is a strongly built, medium-sized bird of prey in the family Accipitridae that is found in eastern and northern Australia.

The grey goshawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae.

[2] Gmelin based his description on the "New Holland white eagle" that had been described in 1781 by the English ornithologist John Latham.

Latham in turn had based his short description on information provided by Johann Forster who had accompanied James Cook on his second voyage to the Pacific Ocean.

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

[8] The specific epithet novaehollandiae is Modern Latin for "New Holland", the name given to western Australia by early Dutch explorers.

They nest in tall trees on a platform of sticks and twigs with a central depression lined with green leaves.
