Chinook High School is a high school (grades 9-12) in the town of Chinook, Blaine County, Montana. Its notable alumni include Mike Tilleman.
As the town of Chinook was known historically for its sugar beet production in the early-to-mid 1900s, the local sugar beet factory donated sugar beet emblazoned uniforms to the high school's boys' basketball team, which is how they became known as the "Sugar Beeters".
