Seeley-Swan High School is an American public high school located in Seeley Lake, Montana, United States.

It is a part of the Missoula County Public Schools, and the only school in the district that does not lie within the city boundaries of Missoula.

This rise and fall of students gives the school the chance to jump back and forth from a class C to a class B school.

Seeley-Swan High School gets its name because the Swan Valley residents commute to Seeley for high school.

It is located between the Swan Range and Mission Mountains.
