Strathcona Provincial Park is the oldest provincial park in British Columbia, Canada, and the largest on Vancouver Island. Founded in 1911, the park was named for Donald Alexander Smith, 1st Baron Strathcona and Mount Royal, a wealthy philanthropist and railroad pioneer. It lies within the Strathcona Regional District. The Clayoquot Sound UNESCO Biosphere Reserve, established in 2000, includes three watersheds in the western area of the park.
