Corvallis High School (CHS) is a four-year public secondary school in Corvallis, Oregon. Originally established in 1910, the high school sat between the downtown area of Corvallis and Oregon State University. In 1935, a new school was built on what was then considered the far northern edge of the town on approximately 25 acres. In 2005, a third structure was built on the site of the former one in what is now considered a central part of the city. Corvallis High School is one of two traditional secondary schools in the Corvallis School District, the other being Crescent Valley High School on the northern edge of the city.
