Dere Street or Deere Street is a modern designation of a Roman road which ran north from Eboracum (York), crossing Stanegate at Corbridge (Hadrian's Wall was crossed at the Portgate, just to the north) and continuing beyond into what is now Scotland, later at least as far as the Antonine Wall. Portions of its route are still followed by modern roads, including the A1 (south of the River Tees) and the A68 north of Corbridge.

The Roman name for the route is lost. Its English name corresponds with the post-Roman Anglo-Saxon kingdom of Deira, through which the first part of its route lies. That kingdom possibly took its name from the Yorkshire River Derwent. The term "street" derives from its Old English sense (from Latin: via strata), which referred to any paved road and had no particular association with urban thoroughfares.

Portions of the road in Scotland were later known as St Cuthbert's Way and as the Royal Way (Medieval Latin: Via Regia).

The Roman equivalent of Watling Street, the Antonine Itinerary's 2nd British route, shared Dere Street's trunk road between Eboracum and Cataractonium (Catterick) before branching off to the northwest to communicate with Luguvalium (Carlisle). Owing to this, some stretches or the entirety of Dere Street is sometimes referenced as "Watling Street". It should not, however, be confused with the traditional route between Canterbury and Wroxeter in the south nor with the Carlisle route to its west.
