Port Hope High School is a high school and former Grammar school in Port Hope, Ontario.
Founded as Port Hope Grammar School in 1853, it existed as grammar and then as a high school from 1850s to 1870s:
After provincial education reforms in 1871, the old Grammar school broke away from the linked Common school (which then renamed Public School) to become a standalone high school.
The current site was built in 1956 with additions added in 1962 and 1970.
The school's honour roll for those students whom served in World War I and World War II were transferred to Port Hope Archives in 2015.
The school shares its building with Dr. M.S. Hawkins, a middle school for Grades 7-8. The High School inhabits the West area of the building, while the Middle School claims the East.
