Lava Fork is a creek in northwestern British Columbia, Canada and the Alaska Panhandle, United States. It lies west of the Unuk River and northwest of Stewart. It flows south from the Lava Lakes across the British Columbia-Alaska border into the Blue River^[1][2] in the extreme northern part of Misty Fjords National Monument.

The Volcano, a cinder cone about 5 km (3.1 mi) north of the British Columbia-Alaska border in northwestern British Columbia, is the source for lava flows that overwhelm the Canadian and American sides of the creek, hence the creek's name.
