Art Gallery of Western Australia, Art museum in Perth Cultural Centre, Australia

The Art Gallery of Western Australia occupies a Brutalist building in the Perth Cultural Centre, designed by Charles Sierakowski of the Public Works Department and opened in 1979. Its Bauhaus-influenced exterior uses a slab and shear-head column system, an innovation in Western Australia at the time. The main building links to the old court house, known as the Centenary Galleries, and the administration sits in the former Police Quarters.

The gallery was founded in 1895 and first shared the Jubilee Building with the state museum and library; its foundation stone was laid in July 1901 by the Duke of Cornwall and York. The main building, designed by Charles Sierakowski of the Public Works Department, opened in 1979, funded in part by the 1970s nickel boom. It connects to the old court house, the Centenary Galleries.

The Lester Prize, one of Australia's richest portraiture awards, has exhibited forty finalists at the gallery each October and November since 2016, when it moved here from its 2007 founding as the Black Swan Prize. The Tom Malone Glass Art Prize, established in 2003, is awarded for contemporary glass art, with winners including Clare Belfrage (2005, 2011) and Mel Douglas (2020).

The main building, opened in 1979, connects to the old court house, the Centenary Galleries. The Administration Building occupies the former Police Quarters designed by Hillson Beasley.
