Government House is the official residence of the governor of Western Australia, situated in the central business district of Perth, the state capital.

The building is a two-storey mansion designed by Edmund Henderson[1] in the early Stuart or Jacobean Revival style, set on 32,000 square metres (7.9 acres) of English gardens in the centre of the Perth business district, between St George's Terrace and the Swan River.

The unique architectural character of the building is characterised by the use of stonework and bonded brickwork, incorporating square mullioned windows, decorated gables and ogival capped turrets.

According to the Western Australian Register of Heritage Places Assessment, Government House is a "unique example of a Victorian Gentleman's residence" set in landscaped gardens with mature plantings and a number of commemorative trees.

This building served successive governors until work began on the new, present-day Government House, for which the foundation stone was laid on 17 March 1859.
