Franklin Glacier Volcano is an eroded caldera complex in the Franklin Glacier area on the southwest flank of the Waddington Massif of the Pacific Ranges of the Coast Mountains in British Columbia, Canada. It last erupted during the Pliocene and could have future activity. It erupted lavas ranging in composition from augite-olivine basalt, through hypersthene andesite, hornblende andesite, and hornblende-biotite andesite, to biotite rhyodacite.

The volcano may be one of the northernmost members of the Cascade Volcanic Arc along with the Silverthrone Caldera, but scientific study has been very limited due to its extremely remote location. Its relationship to volcanism caused by the Cascadia subduction zone (ie. the Cascade Volcanic Arc) has not been firmly established. However, the Pemberton Volcanic Belt is usually merged with the Garibaldi Volcanic Belt and so it is usually part of the arc.

Franklin Glacier Volcano lies within the Coast Plutonic Complex which is the single largest contiguous granite outcropping in the world, extending approximately 1,800 kilometers on the coast of British Columbia, southwestern Yukon and southeastern Alaska.
