St Andrew's Cathedral School is a multi-campus independent Anglican co-educational comprehensive and specialist primary and secondary day school, located in the Sydney central business district, New South Wales, Australia. The school currently caters for approximately 1450 students from Kindergarten to Year 12.

The School is one of Sydney's oldest, founded in 1885, as a choir school for St Andrew's Cathedral, Sydney. St Andrew's is legally supervised by the Cathedral Chapter which appoints and approves members of the School Council which was formed in 1979. The council is responsible for administering the School's policies and formulating its mission and vision as well as appointing successive Heads of School. A boys' school for much of its history, St Andrew's opened its doors to senior girls (Year 10 to Year 12) in 1999. In 2008, the school became a fully co-educational school with boys and girls enrolled from Kindergarten to Year 12. In addition to providing a comprehensive education and a specialist choir school, the School operates an Indigenous primary school, called Gawura.

The School is a member of the International Choir Schools' Association, the Independent Schools Association (ISA), the Association of Heads of Independent Schools of Australia (AHISA), and the Junior School Heads Association of Australia (JSHAA).

In 2009, St Andrew's became an IB World School and commenced offering the International Baccalaureate Diploma as an alternative leaving qualification to the NSW Higher School Certificate (HSC).

The school is also known as the location of the 2023 murder of Lilie James.
