The Cedar River originates near Seastrand Ridge in the Willapa Hills, about a mile east of the Pacific Ocean near Heather and Grayland Beach State Park, just south of Grayland. It flows east, then south, for about 8 mi (13 km) until emptying into the northern end of Willapa Bay near Tokeland, just east of Dexter by the Sea.[2]

The river's lowermost course runs through part of the North Willapa Bay Wildlife Area Unit,[5] part of the Johns River Wildlife Area.[6]

The mouth of the Cedar River merges with Willapa Bay in a tidally-influenced estuary. There is a 275 acre protected unit called the Cedar River Estuary, managed by Forterra. This area is a tidal ecosystem with salt marshes, tidelands, and coniferous forests. It also includes Oyster Island, Bone Creek, and Norris Slough.[7]
