Twelve volcanoes in the arc are over 10,000 feet (3,000 m) in elevation, and the two highest, Mount Rainier and Mount Shasta, exceed 14,000 feet (4,300 m). By volume, the two largest Cascade volcanoes are the broad shields of Medicine Lake Volcano and Newberry Volcano, which are about 145 and 108 cubic miles (600 and 450 km 3) respectively.
This is a list of Cascade volcanoes, i.e. volcanoes formed as a result of subduction along the Cascadia subduction zone in the Pacific Northwest of North America. The volcanoes are listed from north to south, by province or state: British Columbia, Washington, Oregon, and California.

The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m). The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from the Cascade Volcanoes.
The Juan de Fuca tectonic plate is being subducted under the North American Plate, leading to volcanic activity in the Cascades like at West Crater. In southern Washington state, the Cascade Range, which sits south of the dacitic Garibaldi Volcanic Belt, spans 600 miles (970 km) from British Columbia in Canada to Lassen Peak in northern California in the United States.
