The Volcano, also known as Lava Fork volcano, is a small cinder cone in the Boundary Ranges of the Coast Mountains in northwestern British Columbia, Canada. It is located approximately 60 km (40 mi) northwest of the small community of Stewart near the head of Lava Fork. With a summit elevation of 1,656 m (5,433 ft) and a topographic prominence of 311 m (1,020 ft), it rises above the surrounding rugged landscape on a remote mountain ridge that represents the northern flank of a glaciated U-shaped valley.

Lava Fork volcano is associated with a small group of related volcanoes called the Iskut-Unuk River Cones. This forms part of the much larger Northern Cordilleran Volcanic Province, which extends from the Alaska–Yukon border to near the port city of Prince Rupert, British Columbia. Eruptive activity at The Volcano is relatively young compared to most other volcanoes in the Northern Cordilleran Volcanic Province. Geologic studies have shown that The Volcano and its eruptive products were emplaced in the past 400 years; this is well after the last glacial period, which ended about 10,000 years ago.

The Volcano is the southernmost of 10 volcanoes comprising the Iskut-Unuk River Cones volcanic field, as well as the most recent to erupt. Its structure is poorly formed and has been reduced by erosion from alpine glacial ice found at its elevation and latitude. It represents one of the few historically active volcanoes in the Northern Cordilleran Volcanic Province, with a base elevation estimated to be 100 m (330 ft). Like most cinder cones, The Volcano consists of a pile of loose volcanic ash, lapilli-sized tephra and volcanic bombs. These were deposited during periods of lava fountain activity. The vent area contains volcanic bombs up to 0.5 m (1.6 ft) long and small deposits of sulfur precipitated from volcanic gases.
