Sandy Island Marine Provincial Park, formerly Sandy Island Provincial Park and also known as Tree Island Park, is a 30 hectare provincial park in British Columbia, Canada, located off the north end of Denman Island, on the west side of the Strait of Georgia to the south of Comox.

It is accessible by boat and, at low tide, by foot across tidal flats from Longbeak Point on Denman Island.

Jáji7em ("having trees") refers to Sandy Island,[2] while Kw'uhl (unknown meaning) refers to either the Seal Islets or just Seal Island (a.k.a.

Shack Island), the largest of the islets.
