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 Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over 700 miles (1,100 km).
Medicine Lake Volcano — a shield volcano in northern California which is the largest volcano by volume in the Cascades. Mount Shasta (northern California) — second highest peak in the Cascades. Can be seen in the Sacramento Valley as far as 140 mi (230 km) away, as it is a dominating feature of the region. Lassen Peak (south of Mount Shasta ...

The High Cascades are the most recent volcanic arc in the Pacific Northwest, which forms the Cascade Volcanoes. These volcanoes, including the Three Sisters, were fed by magma chambers resulting from the subduction of the Juan de Fuca tectonic plate under the western edge of the North American tectonic plate.

The northern segment consists of one large volcanic complex, the Mount Meager massif, and a group of basaltic and andesitic volcanoes known as the Bridge River Cones. Mount Meager is composed of at least four overlapping stratovolcanoes that become progressively younger from south to north.
