Thetis Island is part of the Gulf Islands chain, off southeastern Vancouver Island. It is separated from Kuper Island, to the south, by a narrow, artificial canal called The Cut. Thetis Island was named
after HMS Thetis—commanded by Captain Kuper during most of its life on the coast.1 This famous, or infamous, ship also gave names to Thetis Anchorage, Cove, and another
Thetis Island.
