Marysvale Canyon or Sevier Canyon /sɛˈvɪər/ is a canyon in Piute and Sevier counties in southwest Utah which runs eight miles (13 km) north from just north of Marysvale north to the town of Sevier. It is a steep walled canyon formed by the flow of the meandering Sevier River. The narrow canyon lies between Sargent Mountain on the northeast corner of the Tushar Mountains to the west and the margin of the small Antelope Range of Sevier County to the east. The canyon ends to the north at the intersection of the Sevier River with Clear Creek Canyon which forms the north margin of the Tushars.
