North Carolina Highway 209 is a primary state highway in the state of North Carolina. The highway runs north–south from Lake Junaluska to Hot Springs.

NC 209 is a 36.6-mile (58.9 km) two-lane mountain highway that begins at a busy intersection with US 19/US 23/US 74/US 23 Bus in Lake Junaluska. Going north, it crosses over I-40 and through some valley farmlands. The road bends east at Max Patch Road and begins some curvy climbing on and around Hebo Mountain, entering Madison County at Betsy Gap (3,895 ft (1,187 m), highest point on route). Entering the Spring Creek Valley, it passes through the communities of Luck and Trust, before reaching Spring Creek; from there the remaining 10 miles (16 km) becomes an aggressively winding road, and is not recommended for commercial trucks. Once past all the twist and turns, travelers arrive in Hot Springs, where the highway ends at US 25/US 70.

Appalachian Medley is an 45-mile (72 km) byway from near Lake Junaluska to Walnut; it is known for several recreational areas, the Appalachian Trail, and its scenic mountain drive. NC 209 forms the main part of the scenic byway, connecting with US 25/US 70, in Hot Springs, where it continues the rest of the route.

Established in 1921 as an original state route, it went from NC 10, in Lake Junaluska to NC 20, in Hot Springs. In 1954, NC 209 was extended a .5-mile (0.80 km) south to its current southern terminus.
