Kingston Collegiate and Vocational Institute (KCVI) was a secondary school in Kingston, Ontario, Canada. Founded in 1792 by Reverend John Stuart based upon a grant for secondary education in the colony of Upper Canada, it moved to its location at 235 Frontenac Street in 1892. It is considered the oldest public secondary school in Ontario and the second oldest in Canada. The site and remaining buildings were purchased by Queen's University in 2021.
