École secondaire publique Mille-Iles (Thousand Islands Public High School) is a high school located in Kingston, Ontario. It was founded in 1994, having initially started as a French program within Kingston Collegiate and Vocational Institute (KCVI) in 1977. In 1980 this became a separate module, serving students in grades 9 to OAC. The establishment of a distinct francophone public high school was first suggested in 1987, and the project came to fruition in 1994, leading to the inauguration of Mille-Iles as a distinct entity in 1995, still within the KCVI building.
