Kelston Boys' High School ("KBHS") is an all-boys state secondary school in Kelston, a suburb in the Waitakere region of Auckland, New Zealand. It was created in 1963 when the roll of Kelston High School became too large for the site on the corner of Archibald and Gt North Rds. The boys moved to a new site further down Archibald Road, leaving the original site to be the home of Kelston Girls High School.

Kelston is a residential suburb of West Auckland, New Zealand. Originally a ceramics manufacturing centre, the area is now mostly residential, including a number of schools. Kelston is located in, and its name has been given to, the Kelston parliamentary electorate.
