Volcanoes of the Northern Cordilleran Volcanic Province are a part of the Pacific Ring of Fire. The largest and most persistent volcanoes are the Mount Edziza volcanic complex and Level Mountain in northwestern British Columbia which have had volcanic activity for millions of years. In the past 7.5 million years, the Mount Edziza volcanic complex has had five phases of volcanic activity while Level Mountain north of Edziza has had three phases of volcanic activity in the past 14.9 million years. The Mount Edziza volcanic complex has been made into a provincial park since 1972 to protect its volcanic landscape. The 102 Northern Cordilleran volcanoes in the list below are grouped into their political regions in north-south order.
