Clayoquot Sound is an area on the west side of Vancouver Island, off the south coast of British Columbia, Canada. The Sound has become widely publicized for controversy regarding its old-growth forests, but has also been the site of conflict over park development, aquaculture, and First Nations treaty claims. Through numerous land-use planning exercises and government policy initiatives, "Clayoquot Sound" has become defined geographically, as a 350 000 hectare collection of islands, fjords, beaches, mountains, forests, lakes, and streams.

The forests of the area are part of the little remaining coastal temperate rainforest which, at one point, lined the west coast of North America. Clayoquot Sound is also home to the Ahousaht, Tla-o-qui-aht, and the Hesquiaht nations--three central region groups of the Nuu-chah-nulth First Nations. The communities of Tofino, Ucluelet and Port Alberni also lie in and around the area, and have been extensively involved in the politics of Clayoquot Sound.
