The '''Tees–Exe line''' is a northeast-southwest line that can be drawn on a map of [[Great Britain]] which roughly divides the island into lowland and upland regions.

The line links the mouth of the [[River Tees]] between [[Redcar]] and [[Hartlepool]] in the north east of England with the mouth of the [[River Exe]] in [[Devon]] in the south west. To the south and east of this line, the landscape, whilst not always flat, is mostly lower and is characterised by flat-lying or gently tilted or folded [[sedimentary rock]]s. North and west of this line are the older, generally harder rocks including [[igneous rock|igneous]] and [[metamorphic rock]]s and the [[Palaeozoic]] and [[Precambrian]] sandstones and limestones which usually stand out as upland areas.<ref>Monkhouse, F.J. 1971 ''Principles of Physical Geography'' University of London Press, London</ref> The areas to the north and west of the line also have a generally wetter climate than areas to the east and south. The varying ease of [[agriculture]] above and below this line historically has left a visible effect on the [[Demographics of the United Kingdom|population density of the UK]], with a concentration of settlements in the south-east.<ref>{{cite journal |last1=Vieno |first1=M.|last2=Heal |first2=Mathew|last3=Williams|first3=Martin|last4=Carnell |first4=Edward|last5=Nemitz |first5=Eiko|last6=Stedman |first6=J.|last7=Reis |first7=Stefan |date=Jan 2016 |title=The sensitivities of emissions reductions for the mitigation of UK PM2.5 |url=https://www.researchgate.net/publication/292189735 |journal=Atmospheric Chemistry and Physics |volume=16 |issue=1 |pages=265–276 |doi=10.5194/acp-16-265-2016 |s2cid=31358734 |access-date=6 June 2023|doi-access=free |hdl=20.500.11820/43929e73-de6d-43e3-b841-aead5d497193 |hdl-access=free }}</ref>

Other lines can be drawn, for similar purposes, between the [[Severn Estuary]] and [[the Wash]], and between the Severn and the mouth of the [[River Trent]]. The [[Cross Country Route]] follows the line by railway along most of the length.
