Wallace Island Marine Provincial Park is a provincial park in the Gulf Islands of British Columbia, Canada. The park includes almost all 72 hectares (180 acres) of Wallace Island. Land on the northern side of Princess Cove extending north towards Chivers is private. This long, thin island lies in Trincomali Channel south-west of Galiano Island, and about 2 km (1.2 mi) northeast of Saltspring Island. There are a few hiking trails, and camping is permitted in designated areas. The island was named for Captain Wallace Houston of HMS Trincomalee who served in the area in 1853.
