Gwaii Haanas National Park Reserve, National Marine Conservation Area, and Haida Heritage Site, usually referred to simply as Gwaii Haanas, is located in southernmost Haida Gwaii, 130 kilometres off the mainland of British Columbia, Canada. Gwaii Haanas protects an archipelago of 138 islands, the largest being Moresby Island and the southernmost being Kunghit Island. "Gwaii Haanas" means "Islands of Beauty" in X̱aayda kíl, the language of the Haida people.

Haida Gwaii, also known as the Queen Charlotte Islands, is an archipelago located between 55–125 km (34–78 mi) off the northern Pacific coast of Canada. The islands are separated from the mainland to the east by the shallow Hecate Strait. Queen Charlotte Sound lies to the south, with Vancouver Island beyond. To the north, the disputed Dixon Entrance separates Haida Gwaii from the Alexander Archipelago in the U.S. state of Alaska.
