Jedediah Island Marine Provincial Park, Marine provincial park on Jedediah Island, British Columbia, Canada

Jedediah Island Marine Provincial Park covers 603 hectares in British Columbia's Sabine Channel, between Texada and Lasqueti islands: 293 hectares of land, mainly Jedediah Island plus nearby islets, and 310 hectares of surrounding water and foreshore. The island's Coastal Douglas-fir zone holds Douglas fir, juniper, coastal fir and arbutus, with salal and Oregon grape beneath.

Coastal Salish groups, especially the Sliammon and Nanoose, used the island for hunting and fishing long before settlement; four archaeological sites, including a First Nations fish weir, remain. The Mattice family bought it in 1949, and Mary Palmer sold it after Lasqueti Island residents raised over four million dollars in under six months in 1994. The park was established on 13 July 1995, and its status and boundaries were redefined in 2008.

The island was hunting and fishing ground for Coast Salish groups, especially the Sliammon and Nanoose, before European settlement. Four registered archaeological sites lie within the park, including a First Nations fish weir, and oral history confirms the island's role in food gathering.

Reaching this place requires taking a boat from a nearby island. Visitors should bring plenty of drinking water since no water supply exists on the property.

In summer 2007 a visiting family found a human foot on a beach here, the first of a series of feet later found around the Salish Sea; it was traced to a man missing since 2004, with no foul play suspected.
