The Schoolhouse at Truxton Canyon Training School, which has also been known as the Truxton Canyon Indian School and as the Valentine Indian School, is a historic schoolhouse that was built in 1903. It was built using Colonial Revival architecture as a work of the Office of Indian Affairs, and was expanded, compatibly with the Colonial Revival style, in 1929. It was listed on the National Register of Historic Places in 2003. The school operated from 1903 until 1937. At the time of its NRHP nomination it was owned by the Hualapi Indian nation, which had plans to renovate the building.
