Applecross Senior High School is a public co-educational high school, located in Ardross, a southern suburb of Perth, Western Australia.

Founded in 1958, Applecross Senior High School has traditionally been one of the leading public high schools in Western Australia and consistently ranks academically within the top ten secondary schools in the state. Applecross has produced two Rhodes Scholars.

Applecross runs dedicated art, tennis and chess programs, and has traditionally been dominant in these areas. It also runs Academic Extension classes, for those students talented in the areas of English, Maths, Science, Society and Environment, French and Japanese.

Like many Western Australian high schools, Applecross is a partially selective high school with out-of-area students accepted on a number of criteria.

The school was opened in 1958 to service the rapidly growing south-of-the-river suburbs of the city of Perth. As of 2021, 1731 students from Years 7 to 12 attended the school.

In 2009 the Government of Western Australia allocated A$56 million for the re-development of the school. A competitive tender process was completed in April 2010. The original school 'H' block, science block, swimming pool, and the 1970s gymnasium was retained. All other existing buildings were removed. A new south wing on the site of the existing tennis courts was designed to house a new administration area, library, resource centre, science, home economics and health and physical education wings. A new design, and technology centre was constructed to the east of the swimming pool and a new visual arts centre was located on the site of existing basketball courts. The gymnasium was converted into a performing arts centre, while the original 'H' block was refurbished for use by business/information technology, careers and vocational education, English, languages, mathematics, society and environment and student services.

The school crest is a combination of a black swan holding a book, signifying proximity to the Swan River, with a hand holding a scimitar, emerging from a five-pointed crown ("issuant from an eastern crown or, a dexter hand holding a scimitar, in fess all proper"), the crest of the Chief of the Matheson clan. Sir Alexander Matheson Bt of Lochalsh, a property developer who in 1897 initiated the subdivision of the suburb of Applecross, became Chief of the Clan in 1920 on the death of his brother, the 2nd Baronet.

The Year-12 cohort at Applecross perform consistently well in the WACE school rankings, and the school ranks well when compared to other schools in Western Australia.
