Lava Lake is a lava dammed lake located in northwestern British Columbia, Canada. The lake lies within the Nisga'a Memorial Lava Beds Provincial Park, which includes fishing, hiking and other features.

Lava Lake increased in size and depth when lava from the Tseax Cone dammed the Tseax River in the 18th century. The flow subsequently traveled 11 km (7 mi) north to the Nass River, where it filled the flat valley floor for an additional 10 km (6 mi), making the entire lava flow approximately 22.5 km (14 mi) long. This is one of Canada's youngest lava flows.
