U.S. Route 199 (US 199) is a U.S. highway in the U.S. states of California and Oregon. The highway was established in 1926 as a spur of U.S. Route 99, which has since been replaced by Interstate 5. US 199 stretches 80 miles (130 km) from U.S. Route 101 near Crescent City, California northeast to Interstate 5 in Grants Pass, Oregon. The highway is the northern portion of the . In Oregon, US 199 is officially known as Redwood Highway No. 25. The majority of the road in California is the Smith River Scenic Byway, a National Forest Scenic Byway. This route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System. The first roadway, a plank road, from Crescent City was established in May 1858, and before the US 199 designation was applied to the highway, the roadway was designated Highway 25 and Route 1.

US 199 begins at a partial interchange with US 101 northeast of Crescent City; Elk Valley Cross Road (County Route D2) connects the two routes just to the north for full access. The highway quickly enters the Jedediah Smith Redwoods State Park, climbs over a ridge, crosses the Smith River, and meets State Route 197 (which heads northwest to US 101 via the Smith River). US 199 follows the banks of the river and its Middle Fork as it takes a steady but curvy climb through the Smith River National Recreation Area in the Six Rivers National Forest, passing the settlements of Hiouchi, Gasquet and Patrick Creek. As it approaches the summit, the Middle Fork Smith River turns east, but US 199 continues northeast, following Griffin Creek to near its source (where there is a rest area), and passing under Hazel View Summit, the border between the Smith River NRA and the Rogue River-Siskiyou National Forest, in the 1963 Collier Tunnel (elevation about 2100 feet/650 m). (The old curving route over the summit still exists as Oregon Mountain Road.) Upon leaving the tunnel, US 199 descends alongside the small Broken Kettle Creek into the Elk Valley and crosses into Oregon.
