High school is a term used in parts of the English-speaking world to describe institutions which provide all or part of secondary education, but not always the highest years of basic education, which can be called a "secondary school" or "secondary college" or other terms, depending on the nation or region (see below: Usage by country). The phrase "high school" is often incorporated into the name of the related institutions.

The term (as "high school") originated in Scotland, with the world's oldest being Edinburgh's Royal High School from 1505. The Royal High School was used as a model for the first public high school in the United States, the English High School founded in Boston, Massachusetts in 1821. The precise stage of schooling provided by a high school differs from country to country, and may vary within the same jurisdiction. In all of New Zealand and Malaysia along with parts of Australia, Bangladesh and Canada, high school is synonymous with secondary school, and encompasses the entire secondary stage of education.
