Dapto High School is a government-funded co-educational comprehensive secondary day school, located in Dapto, a suburb of Wollongong in the Illawarra region of New South Wales, Australia.

Established in 1958, the school enrolled approximately 900 students in 2018, from Year 7 to Year 12, of whom six percent identified as Indigenous Australians and nine percent were from a language background other than English. The school is operated by the New South Wales Department of Education; the principal is Joel Burnett.

In 2002, Dapto was the subject of a case study for its school-to-work program, which chronicled how the school innovated a centralized reporting program via school reports, which turned around an otherwise unsuccessful program and made the program a "whole new approach" which was recommended for other schools. As a result of this program the school's careers advisor, Steve Heinecke, was awarded the title of top careers advisor in New South Wales in 2005.
