Chetco Peak is a mountain in the Klamath Mountains of southwestern Oregon in the United States. It is located in the southern Kalmiopsis Wilderness in southern Curry County in the extreme southwestern corner of the state, approximately 15 miles (24 km) inland from the Pacific Ocean and 10 miles (16 km) north of the California state line. The name of the peak and that of the nearby Chetco River was derived from the name of a small tribe of Native Americans, the Chetco people, who originally lived along the lower Chetco River in Curry County.
