The Winchuck River (Tolowa: duu-sr-xuu-shi taa-ghin-li~'[6]) is a short coastal stream that runs through the Rogue River–Siskiyou National Forest to the Pacific Ocean in the U.S. states of Oregon and California.

Flowing generally west from its origin near Elk Mountain, the river enters the sea at Crissey Field State Recreation Site,[7] about 1⁄2 mile (0.80 km) north of the Oregon–California border and about 5 miles (8 km) south of Brookings.

[9] The main stem and tributaries support chinook and coho salmon, steelhead, and sea-run coastal cutthroat trout.

Fishing from boats is not allowed, but Winchuck River Road provides public access in places.

[11] Flora in the watershed's forests include Douglas-fir, bigleaf maple, and madrone, typical of the Southern Oregon Coast Range, the coastal Siskiyou Mountains, and the Redwoods Zone.
