Kennedy Lake is the largest lake on Vancouver Island, British Columbia, Canada. Located northeast of Ucluelet on the Island's central west coast, the lake is formed chiefly by the confluence of the Clayoquot and Kennedy Rivers. Outflow is via a short stretch of the Kennedy River into Tofino Inlet. The lake includes an extensive northern arm, called Clayoquot Arm. The region's natural beauty has led to portions of it being protected from the Island's active logging industry. Parks adjacent to the lake include Clayoquot Plateau Provincial Park, Clayoquot Arm Provincial Park, Kennedy Lake Provincial Park, and Kennedy River Bog Provincial Park. The lake is a popular recreation destination with boaters and fishers. It is important spawning habitat for sockeye and various species of salmon, and trout.
The lake is part of the ancestral lands of the Tla-o-qui-aht First Nations, and is named for the last governor of the Colony of Vancouver Island, Sir Arthur Kennedy.
