Sierra Club of/du Canada (SCC) is a Canadian, volunteer-based environmental organization. It is part of the environmental movement.

The roots of the Sierra Club of Canada go back to 1963, when environmentalists in British Columbia affiliated themselves with the Sierra Club of the United States (many of these individuals were prominent in the founding of Greenpeace). The Sierra Club of Canada became a pan-Canadian organization in 1989, and was legally incorporated as a Canadian organization in 1992.

As of 2005 it has approximately 10,000 supporters. Its main office is in Ottawa.
