The Canyonside School is a schoolhouse located south of Jerome, Idaho, USA. The lava rock building was constructed by the stonemason H.T. Pugh in 1920; it was one of four stone rural schools built by him. The school replaced several wooden school buildings in the area and was considered a sign of the region's agricultural prosperity, as farming in the area was profitable enough to sustain long-term investments in its educational infrastructure. The building is now a private home.
The school was listed on the National Register of Historic Places in 1983.
