Nestucca Bay National Wildlife Refuge is a U.S. National Wildlife Refuge on Oregon's coast. It is located in southern Tillamook County, on the state's northern coast. It is one of six National Wildlife Refuges comprising the Oregon Coast National Wildlife Refuge Complex and supports one tenth of the world's dusky Canada goose population. The refuge contains at least seven types of habitat, including tidal marsh, tidal mudflats, grassland, woodland, pasture, forested lagg—a transition between raised peat bog and mineral soil—and freshwater bogs, including the southernmost coastal Sphagnum bog habitat on the Pacific Coast.
