Heathridge is a suburb of Perth, Western Australia, located 33 kilometres (21 mi) south of Yanchep within the City of Joondalup.

Heathridge was chosen as the suburb name because of the heath type vegetation growing on the sand ridges of the area, as well as its isolation from the Perth central business district.

The name Heathridge, chosen for the ground-cover vegetation growing on the sand ridges in the area,[2] was first proposed by the developer, Kaiser Aetna, and was accepted by the government's Nomenclature Advisory Committee on 8 November 1974.

The Metropolitan Region Planning Authority rezoned the north and east of the suburb in 1978 for urban development,[5] and land progressively became available throughout the suburb in the 1980s, particularly in the Heathridge Heights area bounded by Hodges Drive to the North, Caridean Street and Poseidon Road to the East, Mermaid Way to the South, and Marmion Avenue to the West.

Heathridge is bounded by Hodges Drive to the north, the Mitchell Freeway to the East, Ocean Reef Road to the south, and Marmion Avenue to the West.

[7] Other facilities within the suburb include the Heathridge Shopping Centre, with restaurants, grocery and liquor stores, on Caridean Street near Admiral Grove.

[8] At state parliament level, Heathridge is represented in the Western Australian Legislative Assembly by a member from Joondalup electoral district.

There are three dedicated houses of worship, belonging to the Church of Jesus Christ of Latter-day Saints, the Salvation Army, and a Pentecostal Anglican group.

From its opening in 1990 until 1995, Belridge progressively expanded its age range until becoming a full secondary school in 1995 when the first class of graduating Year Twelve students commenced their studies.
