The A689 is a road in northern England that runs east from the A595, 3.1 miles (5.0 km) to the west of Carlisle in Cumbria, to Hartlepool in County Durham.

Crossing the River Eden and the West Coast Main Line, the road intersects with Junction 44 of the M6 at Greymoorhill.

From here, the A689 heads east, and crosses the River Irthing at Ruleholme, then it meets the A69 at a roundabout junction.

The route continues roughly south-east, and re-enters the county of Cumbria just north of the small market town of Alston.

After passing through Alston, the A689 eventually crosses the border into County Durham, where the route still heads gradually south-east through Weardale.
