West Perth is an inner suburb of Perth, the capital city of Western Australia.

Formerly an exclusive suburb for wealthy merchants and politicians, it is now part of the inner mixed zone, and has predominantly office blocks which have displaced residential buildings.

There is a high proportion of miners and consultants, and particularly medical specialists, compared to the Perth CBD. Streets such as Colin Street, Ord Street and Outram Street have significant office and high density residential buildings.

Most retail outlets are located on Hay Street which is the main commercial zone for the suburb, and these are focused on serving the office population.

Closer to the CBD the Harbourtown factory outlet complex located near the eastern edge of the suburb, and the City West complex. This location was home to the Perth Metropolitan Markets from 1929 to 1989, when they moved to Canning Vale.

Parliament House is located overlooking St Georges Terrace and Mitchell Freeway, and is at the centre of the Parliament precinct. Also in the precinct is Dumas House, the original Perth Observatory, the second location of Hale School, Solidarity Park, Edith Dircksey Cowan Memorial, and the Constitutional Centre of Western Australia.
