The A68 is a major road in the United Kingdom, running from Darlington in England to the A720 in Edinburgh, the capital of Scotland.

The road passes through rural Northumberland, following the route of Dere Street for much of this stretch, which is considered highly scenic.

[8] Until September 2008, the A68 passed through Dalkeith; the opening of a bypass removed large volumes of traffic from the town centre and led to a reduction in accidents.

[17] Along with the A696, the A68 forms an alternative route between Newcastle Upon Tyne and Edinburgh to the A1 which runs along the coast via Berwick Upon Tweed, and is the more scenic of the two.

[18] The A68 follows the Roman Dere Street north of Corbridge, crossing Hadrian's Wall, and shares its route as far as the historic camps of Habitancum and Bremenium.
