Nisga'a Memorial Lava Bed Provincial Park (Nisga'a: Anhluut'ukwsim Lax̲mihl Angwinga'asankswhl Nisg̲a'a) is a provincial park in the Nass River valley in northwestern British Columbia, Canada, about 80 kilometres north of Terrace, and near the Nisga'a Villages of Gitlakdamix and Gitwinksihlkw.

The park was established by Order in Council on April 29, 1992, expanded in 1995, included in the Nisga'a Treaty in 2000, and is the first park in the province to be jointly managed by the government and a First Nation. An interpretive centre in a traditional Nisga'a longhouse informs visitors about the Nisga'a legend that accounts for the lava as well as geological causes.

The park has waterfalls, pools, cinder cones, lava tree molds, lava tubes, spatter cones, lava-dammed lakes, caves and other features created by lava flows. The park aims to protect moose, goats, marmots, bears and many other species of wildlife.

The park covers 178.93 square kilometres in area.

It is believed to be the site of Canada's most recent volcanic eruption and lava flow, a geological disaster that killed an estimated 2,000 people.

The source of the eruption was the Tseax Cone. Large lava flows dammed the Nass River and destroyed two villages of the Nisga'a people around the year 1700. Lava beds rise as much as 12 metres above the modern road.

Nisga'a oral histories record the names of the two villages destroyed in the eruption, Wii Lax K'abit and Lax Ksiluux.
