The River Teign is a 31 mile long river in Devon.
The Teign rises on Dartmoor. There are two separate sources, the longer North Teign, which rises at Teign Head and flows northeast where it is crossed by a clapper bridge near Teigncombe. The second is the South Teign, which rises near Grey Wethers before flowing through the Fernworthy Forest and a reservoir of the same name. The rivers combine at Leigh Bridge near Chagford to form the Teign, which leaves the moor on its eastern side, flowing beneath Castle Drogo in a steep-sided valley.
It then flows southwards at the east edge of the moor. The river lends its name to several places on its course to the English Channel, including Teigncombe, Drewsteignton, Teigngrace, Kingsteignton , Bishopsteignton, Teignharvey, Canonteign and the second largest settlement along its course, Teignmouth. The river becomes tidal at Newton Abbot and reaches the English Channel at Teignmouth. Its estuary is a large ria.
