Port Huron High School (PHHS) was founded in 1868, and has been in continuous operation as a secondary school in Port Huron, Michigan since then.
Port Huron High School was originally located at what is now the site of St. Clair Community College. The original building was built in 1870, then rebuilt in 1874 and 1908 after it was twice destroyed in fires. In 1957, the high school moved to its current location and building.[4]
In 2024, the U.S. News & World Report ranked Port Huron High School as between 480th and 673rd in the state.[5] PHHS athletic teams competed in the Eastern Michigan League (EML) until the 1990s; upon dissolution of the EML, PHHS joined the Macomb Area Conference (MAC). The athletic teams are known as the "Red Hawks", a reference to the school colors—red, white and black. The name was changed in Spring, 2023.[6]
