Anhluut'ukwsim Laxmihl Angwinga'asanskwhl Nisga'a, Provincial park in Regional District of Kitimat-Stikine, Canada.

Anhluut'ukwsim Laxmihl Angwinga'asanskwhl Nisga'a, also known as Nisga'a Memorial Lava Bed Provincial Park, is a 17,893-hectare provincial park in the Coast Mountains of northwestern British Columbia, Canada, about 80 kilometres north of Terrace. Its centrepiece is a lava field roughly 10 by 3 kilometres, formed by the Tseax Cone eruption, with block lava, ʻaʻā and pāhoehoe, a cinder cone, lava tubes and tree molds. The park also contains Lava Lake, dammed by the flow, and Vetter and Beaupre falls.

Around 1700, a volcanic eruption buried several Nisga'a villages under lava and ash, killing many people and reshaping the Nass River valley. The park was established in 1992 to protect this landscape and to honor the memory of those who died.

The park's Nisga'a name, Anhluut'ukwsim Lax̱mihl Angwinga'asankswhl Nisg̱a'a, is used alongside the English name Nisga'a Memorial Lava Bed. An interpretive centre housed in a traditional Nisga'a longhouse presents the Nisga'a account of the lava alongside its geological explanation. Trails to the lava field carry signs referring to Nisga'a stories and legends, and Nisga'a oral histories name the two villages lost in the eruption, Wii Lax K'abit and Lax Ksiluux.

The park is far from major cities, so arriving by car is the most practical option, as public transport to the area is limited. The lava field terrain is rough and uneven, so sturdy footwear is strongly advised before setting out on any of the trails.

When the lava flowed into the valley, it blocked the course of the Nass River and created a lake that still exists today. That lake was not carved by glaciers or fed by rainfall alone but formed entirely by the movement of volcanic rock.
