Portland Island is an island in the Southern Gulf Islands of the South Coast of British Columbia, Canada. It is located west of Moresby Island and off the south tip of Saltspring Island, adjacent to the main BC Ferries route just offshore from the terminal at Swartz Bay at the tip of the Saanich Peninsula. Portland Island was given to Princess Margaret in 1958 to commemorate her visit to the province. Princess Margaret returned the island to British Columbia in 1967, after which point it became a Provincial Park. Today, Princess Margaret (Portland Island) is a part of Gulf Islands National Park Reserve(GINPR).
