The Canyon Mountains are a 25-mile (40 km) long mountain range located in the northeast corner of Millard County, Utah; the range is bisected north-south with a southeast border section of Juab County.

The Canyon Mountains are part of the north section of the Fishlake National Forest, but the west of the range borders the northeast of the Sevier Desert, and the adjacent Sevier River.

The range is a small Basin and Range Province section of mountains that merge into the smaller Gilson Mountains north traversed by Utah route 132.

The massif of the Pavant-Tushar Mountains are south; the river flows north along the east flanks, then north-northeast along the east flank of the Valley Mountains, then northwest along the north of Little Valley, then northwest, then due-west past the Gilson and Canyon Mountains into the Sevier Desert.

The river turns southwest to Leamington, then Delta, then due-west towards the west Sevier Desert.
