Perth Hills is a term used primarily for marketing purposes to identify the part of the Darling Scarp and hinterland east of the scarp that lies within the Shire of Mundaring, City of Swan, and the City of Kalamunda and as part of the constituent bodies belonging to the Eastern Metropolitan Regional Council of Perth, Western Australia. In earlier usage of the term "The Hills" by people living in Perth, the identification of specific locations along the Darling Scarp (also called the Darling Range) found some places more commonly referred to than others.
