The Alert Bay Volcanic Belt is a heavily eroded Neogene volcanic belt in northern Vancouver Island, British Columbia, Canada. The belt is now north of the Nootka Fault, but may have been directly above the fault at the time it last erupted.

The Alert Bay Volcanic Belt is poorly studied, but appears to have been active in Miocene to Pliocene time. No Holocene eruptions are known, and volcanic activity in the belt has most likely ceased. FeaturesThe features within the belt include:
