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.

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.

The A689 meets the A19 near Wolviston, before turning north-east and eventually terminating close to the centre of Hartlepool.
