Royal York Collegiate Institute (Royal York CI, RYCI, or Royal York) is a former public high school that existed from 1953 to 1982 under the Etobicoke Board of Education (now known as the Toronto District School Board) in The Queensway – Humber Bay neighbourhood of the Etobicoke district in Toronto, Ontario, Canada.

It was the first academic high school built in Etobicoke after World War II.

It had an active sports program and many championship wins over the years.

[1] With declining enrollment, Royal York Collegiate Institute, along with New Toronto Secondary School (later Lakeshore Collegiate Institute), Kingsmill Secondary School (later Bishop Allen Academy), and Alderwood Collegiate Institute underwent a review in 1980 as many Catholic immigrants who arrived in the area transferred their children to the separate school system when full separate school funding commenced.

As a consequence, Royal York Collegiate closed in June 1982.
