This is a list of heritage buildings in Perth, Western Australia, a district occupied by British settlers in 1829 and originally named the Swan River Colony. The places are listed in chronological order and include significant buildings in the Perth metropolitan area. Included are examples of governmental, religious, residential, commercial and institutional buildings. Places of identified heritage significance in metropolitan and regional Western Australia are listed in the official "InHerit" database which includes the State Register of Heritage Places, local government inventories and other lists, the Australian Government's heritage list, and other non-government lists and surveys.
Western Australia’s settlements struggled in the 1800s from lack of resources, labour and investment. The gold rushes of the 1890s brought a great influx of people from interstate and overseas, and considerable development arising from the new wealth. Many ornate and substantial buildings were constructed in the metropolitan area from the 1890s to the early-mid 1900s, including the Palace Hotel, Perth, the Esplanade Hotel, Fremantle, His Majesty's Theatre, Perth and the Old Perth Technical School.
In the late 1950s, a group of individuals who were concerned for the need to ‘preserve our heritage’ came together to form the National Trust of Australia (WA) in 1959. The National Trust’s mandate was to educate the public on the importance of valuing our landscapes. At this time, there was no legislation or a statutory body in WA to formally recognise and protect heritage places. The National Trust was able to promote and bring attention to the significance of the state's heritage places including natural landscapes and buildings which were supported by heritage assessments of buildings with a classification system. In 1965, an Act of Parliament established the National Trust as a statutory body in WA and properties were able to be vested under the responsibility of the organisation.
A mining boom in the 1960s-70s led to another wave of intensive development in Perth and as a result the city lost many of its early 1900s buildings, particularly along St Georges Terrace. From this time, a greater awareness in the community of the loss of heritage places developed as demonstrated by several high profile public campaigns for the Pensioner Barracks (now the Barracks Arch), the Palace Hotel on St Georges Terrace and the Swan Brewery.
