State Route 180A (SR 180A) is a highway in Apache County, Arizona, that runs from its junction with US 180 to SR 61 west of St Johns. It is a north–south route for the entirety of its 10-mile (16 km) length.
SR 180A follows the original alignment of US 180 before the more direct route from St Johns to its current junction with SR 180A was built. The southern terminus of the highway is located at a junction with SR 61 near the community of Concho. It heads northerly from this intersection to its northern terminus at a junction with US 180 northwest of St. Johns. SR 180A now serves as a bypass route for north–south traffic wishing to avoid St Johns. SR 180A has no junctions with any highways aside from its endpoints.
The route was established by the Arizona Department of Transportation in 1974. Since then, the route remains as defined.
The entire route is in Apache County.
